Affording a home in Ohio depends heavily on local prices: the median is $225,000, but markets like major metro areas can run 30–50% higher. Property taxes at 1.56% add $3,510/year to the cost of owning a median-priced home, which lenders factor into your debt-to-income ratio. Insurance in Ohio averages $1,010/year. Your 3.5% state income tax reduces disposable income available for mortgage qualification. The cost of living index is 91.9 (100 = national average).

Ohio Financial Snapshot (2026) — Mortgage Affordability Calculator

Home value, monthly carrying cost, property tax, and insurance are the four levers for the mortgage affordability calculator in Ohio. Every row cites a primary public dataset. Numbers reflect the most recent vintage available; refresh cadence is documented in the methodology.

How the Mortgage Affordability Calculator Math Works Under Ohio Law

Every real-estate number on this page runs through the same core identity: the monthly principal-and-interest payment on a fully amortizing fixed-rate loan is M = P · r / (1 − (1+r)^(−n)), where P is the loan principal, r is the monthly rate (annual rate / 12), and n is the term in months. For a typical Ohio buyer in 2026, P starts from an $225,000 median home value (Zillow ZHVI)[1], minus a standard 20% down payment.

On top of P&I the calculator adds the two Ohio-specific carrying costs: property tax at the state effective rate of 1.56%[2] and homeowners insurance at roughly $1,010/year (NAIC state average)[3]. The Freddie Mac PMMS national average 30-year fixed rate (6.30% (Freddie Mac PMMS · week of May 14, 2026))[4] drives the payment curve — Ohio rate quotes can move a few basis points around that number depending on lender, loan size, and credit band.

Calc-specific note: Lenders cap front-end DTI near 28% and back-end near 43%; plug Ohio's PITI into those ratios to find your gross-income floor.

Worked example — Ohio

For a Ohio buyer aiming at the $225,000 median, a 28% front-end DTI means gross monthly income of at least $1,575 (≈$18,900/year). Subtract 3.5% state tax to get take-home.

Local context: Ohio

Housing economics in Ohio. The median home value runs 37.2% below the U.S. baseline for Ohio is $225,000 per Zillow's home-value index. Effective property tax sits at 1.56% of assessed value, meaningfully higher than the 0.99% national average tracked by the Tax Foundation. Lenders in Ohio have quoted 6.30% on the 30-year fixed product over the trailing four-week window per Freddie Mac PMMS — the prevailing posted rate before any borrower-specific lock-ins.

Income and tax climate. Median household income in Ohio reaches $80,520 per the ACS five-year vintage, pulling above the $78,538 U.S. median. Ohio's top marginal state income tax bracket lands at 3.50% — compared to the volume-weighted national average around 4-5%. BEA's Regional Price Parity scores Ohio at 91.9 (national = 100), meaning a dollar in Ohio buys 109¢ — more goods and services than the same dollar nationally.

How Ohio's numbers shape the calculator. The mortgage payment, refinance, PMI, and home-affordability calculators all run on three local inputs that swing the answer materially: the prevailing 30-year fixed rate, the effective property tax rate as a share of home value, and the homeowners-insurance premium that the average policyholder is paying for the same coverage envelope. Ohio-specific values for each of those are pre-loaded above so the calculator's default scenario reflects what an actual buyer would see at closing, not a national average that smooths over the differences. Override any field to test a different scenario; the math reruns instantly in your browser without sending the inputs anywhere.

Ohio versus the U.S. baseline

How does Ohio stack up against the national average on the metrics that drive the calculators on this page? The table below pairs the Ohio-specific reading against the U.S. baseline so you can see at a glance whether your local scenario runs above or below typical. Three to five percentage points of difference on most of these inputs translates into meaningful changes in calculator output — for example, a 50-basis-point difference in mortgage rate moves the monthly payment on a $400,000 30-year loan by roughly $130.

How to use the Mortgage Affordability Calculator

Walk through using the Mortgage Affordability Calculator with Ohio-specific defaults pre-loaded from primary sources.

  1. Pre-fill with local dataEach calculator on this page loads with state- or city-specific defaults pulled live from primary sources (FRED, BLS, Zillow, Freddie Mac PMMS, IRS, BEA). The blue values shown next to each input are the local averages so you can see how your scenario compares to the typical case before changing anything.
  2. Override the inputs you controlChange any field to model your actual situation. The math reruns in your browser the moment you change a value — no signup, no API call, no data transmission. Hover over the small (i) icon next to each label to see the formula that field feeds and where the default came from.
  3. Read the derived valuesThe result panel shows the primary calculation (monthly payment, take-home pay, savings projection, etc.) plus the intermediate values that drive it. Each line item is labeled with the formula component it represents so you can verify the arithmetic against any agency publication, textbook, or competing calculator.
  4. Adjust assumptions and re-runMost calculators have a section for assumption inputs that are easy to overlook — annual raises, expected return, inflation, vacancy rate, depreciation schedule, marginal vs. effective tax treatment. The defaults are conservative; aggressive scenarios usually require explicit overrides.
  5. Save to "My Numbers"When the inputs match your reality, click Save to "My Numbers". The values persist to your device's local storage (IndexedDB) and reload automatically on your next visit. Nothing is transmitted to any CalcFi server — the saved-state feature is deliberately client-side only for privacy.
  6. Compare scenarios side by sideMost calculators offer a comparison view that shows two or more scenarios side by side. Use this to model decision points: 15-year vs 30-year mortgage, Roth vs Traditional IRA, salary vs hourly, lease vs buy. The comparison view also produces a shareable summary you can download as PNG or PDF.

CalcFi pSEO pages combine three inputs: (1) the calculator formula itself, which runs client-side so no inputs leave your browser; (2) state-level financial constants from primary public datasets; and (3) national benchmarks for comparison. The Ohio page uses the property tax rate (1.56%), median home price ($225,000), and 3.5% state income tax from the sources listed below.

Refresh cadence:state tax brackets and minimum wage rates are reviewed annually after each state's legislative session. Property tax, median home price, insurance, and cost-of-living figures are reviewed annually against the primary sources. Income percentiles are refreshed when the Census CPS/IPUMS releases update (typically September). Page-level dateModified matches the last editorial review date, shown above.

Known limits: statewide averages mask large intra-state variance — county-level property tax and metro-level home prices differ significantly from the figures shown. For the most precise calculations, cross-check the output against your actual county assessor and the latest federal/state tax tables at filing time.

Example: DINK couple in Austin, TX▾

Marcus (34, software engineer, $145k) and Priya (32, UX designer, $98k) are DINKs in Austin. Combined gross: $243,000. They have $120,000 saved, $0 student debt, one car payment of $480/mo.

  • Combined gross income: $243,000/yr ($20,250/mo)
  • Existing monthly debts: $480 (car)
  • Max front-end DTI target: 28%

  • Down payment available: $100,000
  • Rate assumption: 7.0% 30-yr fixed

Takeaway: At 36% back-end DTI they can carry ~$7,290 total monthly debt — $6,810 for PITI after the car payment. Texas has no state income tax, boosting net take-home vs California peers. Travis County effective property tax ~2.0% means a $820k home adds ~$1,367/mo in tax alone — keep that front-of-mind when rate-shopping.

When this calculator is wrong▾
  • Back-end DTI vs. front-end DTI

    This calc uses front-end DTI (housing / gross income). Conventional lenders cap front-end at 28% and back-end (all debt) at 36–45%. If you carry $800/month in car and student loan payments, a 43% back-end cap on $8,000 gross income limits total debt service to $3,440 — meaning your mortgage ceiling is $2,640, not the $2,240 front-end alone implies.

    Debt-to-Income Calculator
  • Variable-income borrowers

    Lenders typically average the last two years of Schedule C or 1099 income — not current year gross. A freelancer who earned $60k in 2024 and $90k in 2025 qualifies on $75k/yr, not $90k. A first-year spike does not help.

  • Stress-testing for rate movement

    The calc uses the rate you input. Qualifying for a $450k home at 6.5% does not mean you can afford it at 8% if your ARM adjusts. A 1.5% rate increase on a $450k loan raises monthly P&I by ~$430.

    Refinance Calculator
  • Down-payment gift fund sourcing rules

    Gift funds must be documented with a gift letter and cannot be a loan. FHA allows full gift down payments; conventional Fannie/Freddie require borrower contribution of 3% minimum on loans above 80% LTV when using gifts. Mis-sourced funds cause last-minute denials.

  • HOA dues reduce effective borrowing room

    HOA dues count as housing expense in front-end DTI. At $500/month HOA, your maximum P&I payment drops by $500 for any given front-end ratio — effectively reducing purchasing power by ~$70k at 7%.

⚡ Key Takeaways

  • The 28/36 rule states housing costs should not exceed 28% of gross income and total debts should not exceed 36%
  • On a $80,000 salary ($6,667/month gross), your maximum housing payment is $1,867/month PITI
  • Lenders use this rule rigidly—exceed it and you may not qualify for a mortgage, or face higher interest rates
  • The rule accounts for principal, interest, taxes, and insurance (PITI), not just principal and interest
  • Down payment significantly impacts affordability: a 20% down payment eliminates PMI and adds ~$50-60/month purchasing power per $10K
  • This rule is conservative; some lenders stretch to 40% DTI for borrowers with excellent credit and reserves

Understanding the 28/36 Rule

The 28/36 rule is the industry standard lenders use to determine mortgage approval. It has two components:

Front-end ratio (28%): Your monthly housing payment (PITI: Principal, Interest, Taxes, Insurance) should not exceed 28% of your gross monthly income.

Back-end ratio (36%): Your total monthly debt payments (housing + car loans + student loans + credit cards + etc.) should not exceed 36% of gross monthly income.

Lenders typically use the more restrictive of the two. If one limits you to $300K home price and the other to $350K, the $300K is your actual cap.

Why Lenders Obsess Over the 28/36 Rule

These ratios exist because they predict default risk. Decades of mortgage data shows that borrowers spending 28-36% of income on housing have dramatically lower default rates than those exceeding these thresholds. Lenders aren't being conservative to protect you—they're protecting their own capital. The rule is mathematically proven to separate safe borrowers from risky ones.

Calculating Your 28% Maximum Housing Payment

Step 1: Annual salary ÷ 12 = Gross monthly income. For example: $80,000 ÷ 12 = $6,667/month. Step 2: Gross monthly income × 0.28 = Max PITI. Example: $6,667 × 0.28 = $1,867/month maximum. Step 3: Work backwards to find max home price using our mortgage affordability calculator to handle the reverse calculation.

How Down Payment Size Changes Your Affordability

Down payment is arguably the most misunderstood variable. Many people think bigger down payment = less you can borrow. Actually, bigger down payment = more you can borrow at same monthly payment. A larger down payment reduces your loan amount, reducing monthly P&I. At the same total monthly payment, you can afford a more expensive home. Example at $2,000/month max PITI (7% rate, 30 years): 5% down ($15K on $300K home) = ~$360K affordability. 10% down ($30K) = ~$375K affordability. 20% down ($60K) = ~$405K affordability. Why? Because 20% down eliminates PMI (Private Mortgage Insurance). At 5-10% down, you're paying $100-200/month in PMI, which counts toward your PITI.

Property Tax and Insurance: The Hidden PITI Killers

Many first-time buyers only think about principal and interest (PI). But PITI includes taxes (T) and insurance (I), which vary wildly by location. Example: Same $400,000 home with $300,000 mortgage at 7%, 30 years. P&I payment = $1,996/month everywhere. New Jersey (1.6% property tax): Add $533/month + $150 insurance = $2,679 total PITI. Texas (0.6% property tax): Add $200/month + $100 insurance = $2,296 total PITI. Florida (0.8% property tax): Add $267/month + $120 insurance = $2,383 total PITI. The same home's PITI payment ranges from $2,296 to $2,679—a $383/month swing (16.7% difference!). This massively impacts affordability.

The Debt-to-Income Ratio Trap

Just because a lender allows 36% DTI doesn't mean it's the right call. At 36% DTI on an $80,000 salary ($2,880/month debt), you have only $4,453/month for food, utilities, gas, childcare, insurance, and savings. That's roughly $1,573/month left after taxes and debt—extremely tight for a family. One job loss, one car breakdown, one medical emergency, and you're insolvent. Healthier approach: Aim for 25-28% DTI housing. Your lender wants you to pay on time. You want to not be financially destroyed. Different goals. Protect yourself first.

How Interest Rates Impact Your Affordability

Interest rates are the hidden variable that demolishes affordability conversations. Same scenario: $2,000/month PITI budget, 30-year, 20% down on home price. At 5% interest: $424,000 home. At 6% interest: $395,000 home. At 7% interest: $370,000 home. At 8% interest: $347,000 home. A 3% interest rate jump reduces home affordability by $77,000—nearly 20%. This is why shopping for rates matters enormously. Get pre-approved by multiple lenders. A rate difference of 0.25-0.5% could save you $50-150/month and unlock $20K-$50K in additional purchasing power.

FAQ: The 28/36 Rule and Home Affordability

Does the 28% rule apply if I'm self-employed?

Yes, but lenders scrutinize self-employed income more heavily. You'll need 2-3 years of tax returns to prove stable income.

Can I use my spouse's income?

Yes. Both spouses' incomes count toward the 28/36 calculation. This is why dual-income households typically qualify for much higher prices.

Should I buy at the maximum the lender approves?

No. Many financial advisors recommend buying 10-20% below your max to preserve flexibility and emergency cushion.

⚡ Key Takeaways

  • You don't need 20% down—FHA loans allow 3.5%, conventional 5-10%, VA allows 0%
  • Less down payment = lower entry cost but higher monthly payment and PMI fees (0.5-1.5% annually)
  • Every 5% increase in down payment removes roughly $40-80/month in PMI costs on a $300K home
  • PMI can be removed once you reach 80% LTV through home appreciation or extra principal payments
  • The true cost of PMI: on a $300K home with 10% down, you'll pay $15,000-30,000 in PMI over 10 years
  • Down payment is NOT the same as closing costs—you need both in savings

The Down Payment Myth

The 20% down payment rule persists because it's historically optimal for lenders. But it's not a requirement—it's a preference. In reality, conventional lenders accept 5% down, FHA accepts 3.5%, and VA accepts 0% for eligible veterans. Think of down payment as a spectrum: 0-5% maximum accessibility/highest costs, 5-10% moderate accessibility/high costs, 10-15% balanced approach, 15-20% getting closer to optimal, 20%+ lender-preferred/lowest costs.

Understanding PMI

Private Mortgage Insurance (PMI) protects the lender if you default—not you. It's basically a penalty for not having enough capital upfront. PMI costs: Typically 0.5-1.5% of loan amount annually. On a $270,000 loan (90% of $300K home), PMI could be $1,012-$3,038/year ($84-$253/month). Better credit = lower PMI. A 740 FICO score pays roughly 30% less PMI than a 620 FICO.

Real Affordability Impact

$400,000 home purchase: 20% down ($80K): Monthly P&I = $1,912, no PMI, total ~$2,112 PITI. 10% down ($40K): Monthly P&I = $2,157, PMI = $160/month, total ~$2,357 PITI. 5% down ($20K): Monthly P&I = $2,280, PMI = $200/month, total ~$2,480 PITI. Dropping from 20% to 5% down reduces upfront cash but increases monthly payment by $368/month—$4,416/year. Over 10 years, that's $44,160 in extra payments.

When Saving for 20% Down Actually Costs More

In certain market conditions, waiting for 20% down costs more than buying with 10% down and paying PMI. Home price today: $300,000. You need 1.5 years to save the additional $15K for 20% down. Home price in 1.5 years (3% appreciation): $346,500. By delaying, you lose the appreciation gain ($46,500) while paying rent. Buying with 10% down and paying PMI is often financially superior to waiting. The mortgage payment builds equity while appreciation works in your favor.

The PMI Removal Strategy

PMI isn't permanent. You can remove it once you reach 80% LTV. Home appreciation + automatic removal: If your home appreciates and reaches 78% LTV, lenders must remove PMI. Principal reduction: Make extra principal payments to reach 80% LTV faster. Refinancing: If rates drop, refinance to a loan with 20% down equity and eliminate PMI.

Closing Costs vs Down Payment

Don't mix them up. Down payment: The money you bring that goes toward purchase price (5-20% of home price). Closing costs: Fees for loan, appraisal, title, inspection, attorney, etc. (2-5% of home price). Example: $300K home purchase needs $30,000 down payment + $9,000 closing costs = $39,000 total cash required.

Low Down Payment Loan Options

FHA Loans (3.5% down): Best for first-time buyers with low credit. Conventional Loans (5-10% down): Best for buyers with decent credit who want PMI removal option. VA Loans (0% down): For military/veterans. USDA Loans (0% down): For rural property buyers.

FAQ: Down Payments and PMI

Can I use a gift for my down payment?

Yes. Most lenders allow down payment gifts from family members with a gift letter.

Should I use my 401k for a down payment?

Almost never. 401k early withdrawals face 10% penalty + income taxes. A $30K withdrawal costs ~$100K in lost growth.

If I have $50K saved, should I put it all down?

Save 3-6 months of living expenses in emergency fund first. Never deplete your emergency fund for a house.

⚡ Key Takeaways

  • Your mortgage payment is just 50-60% of true housing costs—property taxes, insurance, maintenance make up 40-50%
  • Total home ownership cost approximates 1-1.5% of home value annually (taxes, insurance, maintenance)
  • A $400,000 home should budget $333-500/month for maintenance alone
  • Property taxes vary by 300%+ across the US ($3,000-$15,000/year on same $400K home)
  • Closing costs (2-5% of purchase price) are separate from down payment
  • HOA fees range $100-500/month and increase 3-5% annually

The Truth About Total Housing Cost

Most buyers think:"My mortgage is $2,000/month, so my housing cost is $2,000/month." Wrong. Your true monthly cost is P + I + T + M + R + U. P = Principal & Interest. I = Insurance. T = Taxes. M = Maintenance. R = Replacements (major items). U = Utilities. Your mortgage covers only P. The others are your responsibility.

Real Housing Cost Example

Home price: $400,000. Down payment: 20% ($80K). Loan: $320,000 at 6.5%, 30-year. Monthly P&I: $2,023. Monthly insurance: $150. Monthly property tax: $400 (1.2% annual). Monthly maintenance budget: $333 (1% of value ÷ 12). Monthly utilities: $300. Total monthly cost: $3,206 (not $2,023). The buyer budgeting $2,500 is actually spending $3,206—58% more.

Property Taxes: The Biggest Shock

Property taxes vary dramatically by location. Annual tax on $400,000 home: New Jersey (1.57%): $6,280/year ($523/month). Illinois (0.85%): $3,400/year ($283/month). Texas (0.60%): $2,400/year ($200/month). Florida (0.75%): $3,000/year ($250/month). Hawaii (0.28%): $1,120/year ($93/month). That's a $430/month difference on the same house. Over 30 years, that's $155,000 in additional taxes. Before house hunting, look up the exact property tax rate for your county.

Homeowners Insurance

Homeowners insurance typically costs 0.4-0.6% of home value annually. On $400K, that's $1,600-$2,400/year ($133-$200/month). But location matters enormously: Suburban home with no claims: $140/month. Flood zone: $350+/month. High-risk wildfire area: $300-500/month. Older home with claims: $250+/month. Get insurance quotes before making an offer.

Maintenance: The 1% Rule

Budget 1% of home value annually for maintenance. On $400K, that's $4,000/year ($333/month). But actual costs vary wildly. Typical items: HVAC filter ($30-100 quarterly), roof cleaning ($200-500/year), gutter cleaning ($150-300/year), termite inspection ($75-200). Major repairs (every 5-10 years): Roof replacement ($8,000-$20,000), HVAC replacement ($5,000-$10,000), water heater ($1,500-$3,500), foundation repair ($3,000-$25,000), electrical panel upgrade ($2,000-$4,000), plumbing overhaul ($10,000-$25,000).

Closing Costs

Closing costs are separate from down payment. They typically total 2-5% of purchase price. Common costs: Loan origination (0.5-1% of loan), Appraisal ($400-800), Title insurance ($500-1,500), Title search ($100-300), Attorney fees ($500-1,500), Home inspection ($300-600), HOA transfer ($100-300), Property taxes prepaid ($1,000-$5,000), Insurance prepaid ($500-$2,000), PMI upfront (1% of loan), Recording fees ($50-300). Total often $8,000-$15,000.

The HOA Trap

HOA fees increase 3-5% annually. A $250/month HOA today is $350/month in 10 years. Over 30 years compounding 4% annually: Year 1: $3,000/year. Year 10: $4,440/year. Year 20: $6,573/year. Year 30: $9,725/year. Total over 30 years: $154,000 (not $90,000). Before buying, review HOA budget, 5-year fee history, upcoming assessments, and what's covered.

FAQ: Hidden Home Costs

Does property tax change after I buy?

Yes, usually. Most states reassess after purchase. California is the exception (Prop 13 locks taxes at purchase value).

Should I get a home inspection?

Absolutely. A $400 inspection can reveal $10K in repairs and give negotiating power.

Can I roll closing costs into the loan?

Yes, but it increases interest paid. A $10K rolling into a $300K loan costs $18,000+ over 30 years. Pay upfront if possible.

At $80K salary, conservative estimate: $280K-$350K home. Using 28% rule: $1,867/month PITI. With 20% down and 7% rate: ~$325K home price.

Housing costs ≤28% of gross income. Total debt ≤36% of gross. On $100K income: max housing $2,333/month, max total debt $3,000/month.

Most lenders prefer 28% or less of gross monthly income. Financial experts often recommend keeping it at 25% of net (take-home) pay for financial flexibility.

Every $10K more in down payment adds ~$58/month purchasing power at 7%. 20% down eliminates PMI ($100-200/month extra on conventional loans).

Property tax (1-2.5% of value), insurance ($100-200/month), HOA fees, maintenance (1% of value/year), utilities increase, closing costs (2-5% at purchase).

The 28/36 rule says housing costs should not exceed 28% of gross monthly income, and total debt payments should stay below 36%. Lenders use this guideline to determine how much mortgage you can reasonably qualify for.

At $100K salary with the 28% rule, your maximum monthly housing cost is $2,333. At 7% interest with 20% down, this supports roughly a $350,000-$400,000 home depending on local taxes, insurance, and your existing debts.

A larger down payment reduces the loan amount needed, lowering monthly payments and potentially eliminating PMI. Putting 20% down versus 5% on a $400,000 home saves roughly $200 per month and avoids $150-$250 in monthly PMI.

DTI includes minimum payments on credit cards, auto loans, student loans, personal loans, child support, and alimony. It does not include utilities, insurance premiums, groceries, or subscriptions. Paying off debts before applying increases borrowing power.

Each 1% rate increase reduces buying power by roughly 10%. At 6% interest you can afford a $400,000 home, but at 8% the same monthly payment only supports about $330,000. Rate changes dramatically impact how much house you can buy.

Max Housing = Gross Monthly Income × 28%

Max Housing (DTI) = Gross Monthly Income × 43% − Monthly Debts

Use the lower of the two. Then reverse the mortgage formula to find the max loan amount, then add your down payment for max home price.

CFPB qualified-mortgage rules cap DTI at 43% (with 2024 ATR-QM amendments allowing higher with compensating factors). Subtracting $700 existing debt from the $4,838 DTI cap leaves $4,138/mo for PITI. Backing out Ohio property tax ($528/mo on $395k) and insurance ($84/mo) leaves $3,526/mo for P&I — supporting a $569k loan principal at 6.30%. The binding constraint is usually down payment savings, not DTI.

A 36% DTI cap gives $2,850/mo for PITI. New York's 1.72% property tax and modest insurance leave ~$2,280 for P&I — supporting $368k in loan principal. Total price with $60k down = $428k max. This is below NYC median but fine for upstate NY. Geography matters: the same income supports 2x the home in Buffalo vs Queens.

Result: Max $685,000 home — but TX property tax + insurance consume 19% of PITI vs 9% in CA

Income supports aggressive borrowing in TX, but the effective carrying cost is higher per dollar of home because TX has no state income tax offset for property tax (Proposition 2019 homestead cap exists but is modest). Net-of-tax cost is closer to California than the sticker math suggests. Model at 40% DTI for resilience in high-tax states.

DTI ratios use gross income by lender convention, but your actual cash flow depends on take-home. A 43% DTI on gross may be 60%+ on take-home after taxes, 401(k), and healthcare.

Impact: A $10k/mo gross earner with $7k take-home committing $4,300 to housing has only $2,700 left for everything else.

Property tax ranges from 0.28% (Hawaii) to 2.47% (New Jersey) per Tax Foundation. Same home price, same income — NJ buyer can afford 15–20% less house than Hawaii buyer.

Impact: On a $500k home: NJ property tax $12,350/yr vs HI $1,400/yr — $913/mo escrow difference.

The 28% front-end ratio assumes moderate COL. In high-COL metros (NYC, SF, Boston), 28% may still leave insufficient cash for transport, childcare, and groceries. Use 25% front-end in HCOL, 30% in LCOL.

Impact: A $120k earner in SF at 28% housing + 35% childcare is cash-flow negative despite "qualifying".

Closing costs run 2–5% of loan amount. If you have $60k saved and plan 15% down on a $400k home ($60k), you have $0 left for $8k–$15k in closing costs.

Impact: Buyers often scramble at the closing table or take higher rates (lender credits) to cover the gap.
