How Much House Can I Afford? 2026 Guide
28/36 rule: housing (PITI+HOA) ≤28% gross income; all debt ≤36%. Lender max: 43–50% DTI (not what you should spend). Gross vs take-home gap: $100K salary, 28% gross = $2,333/mo = 41.7% of $5,600 take-home. True monthly cost: add maintenance (1–2%/yr = $350–$700/mo), utilities, landscaping. House-poor threshold: housing+debt >45% take-home; cutting retirement contributions; no reserves. Rule: buy 10–25% below what the bank approves.

How Much House Can I Afford? The 28/36 Rule, What Lenders Actually Allow, and What You Should Actually Spend
"How much house can I afford?" is the question every buyer asks and almost nobody answers completely honestly. Lenders tell you the maximum you can borrow (which is not the same as what you should borrow). Online calculators give you the 28/36 rule number (which only covers principal and interest). Neither tells you what "house poor" actually feels like, or how to calculate the real monthly cost of homeownership including the expenses that don't show up on a mortgage payment.
The 28/36 Rule: What It Is and What It Misses
The Classic Guideline
Front-end ratio (28%): your total monthly housing payment — principal, interest, property taxes, homeowner's insurance, PMI, and HOA — should not exceed 28% of gross monthly income (before taxes). Back-end ratio (36%): all monthly debt payments combined — housing + car loans + student loans + credit card minimums — should not exceed 36% of gross monthly income. This is a conservative guideline from mortgage lending history. It predates the consumer debt levels most households carry today.
The Gross vs Take-Home Gap
The 28% rule uses gross income. Your mortgage payment comes out of take-home pay. On a $100,000 salary, gross monthly income = $8,333. 28% = $2,333/month in housing. But after federal taxes (~22%), state taxes (~5%), 401(k) contribution (6%), and health insurance ($400/mo), take-home may be $5,400–5,800/month. $2,333 of a $5,600 take-home = 41.7% of actual spendable income. This is why many households that qualify at 28% of gross feel financially stretched — the guideline looks comfortable on paper but tighter in practice.
What Lenders Actually Allow vs What You Should Spend
| DTI Level | Who Uses It | Risk Level | Real Implication | ||||||
|---|---|---|---|---|---|---|---|---|---|
| 28% housing / 36% total (28/36 rule) | Conservative advisors; traditional guideline | Low | Comfortable; leaves room for savings, emergencies, lifestyle | ||||||
| 31% housing / 43% total (FHA guideline) | FHA loans; most conventional lenders as baseline | Moderate | Standard; manageable for most households | ||||||
| 36% housing / 45% total | Conventional loans with strong compensating factors | Moderate-high | Getting tight; significant debt leaves little margin | ||||||
| 45–50% total debt (lender maximum) | Max most lenders allow with excellent credit/reserves | High | House poor territory; most of take-home goes to debt payments | ||||||
| Key insight: a lender who approves you at 50% DTI has done their job — they've determined you can make the payment. They have no obligation to ensure you have money left for retirement savings, car repairs, medical expenses, or a comfortable life. That assessment is yours to make. | |||||||||
The Real Monthly Cost of Homeownership: Beyond PITI
The mortgage payment (principal + interest + taxes + insurance) is not the total cost of owning a home. Budget for all of these:
| Cost Category | Monthly Estimate | Notes | |||||||
|---|---|---|---|---|---|---|---|---|---|
| Principal + Interest (P&I) | $1,900–2,900 on $350K–$500K loan at 6.5% | The loan payment | |||||||
| Property taxes | $200–$900+ depending on location | Escrowed; 1–2.5% of value annually is common | |||||||
| Homeowner's insurance | $100–$300 | More in hurricane/wildfire zones; escrowed | |||||||
| PMI (if <20% down) | $60–$250 | Eliminated when you reach 20% equity | |||||||
| HOA fees (if applicable) | $0–$1,000+ | Condos and planned communities; often significant | |||||||
| Maintenance and repairs | 1–2% of home value annually = $350–$700/mo on a $400K home | Actual spend varies; budget it before you need it | |||||||
| Utilities (if higher than renting) | $50–$300 more than apartment | Larger space; more HVAC; higher water bills | |||||||
| Lawn and landscaping | $0–$200/mo depending on property | Often underestimated, especially first year | |||||||
| TOTAL TRUE MONTHLY COST | $2,700–4,500+ on a $400K–$500K home | This is the number to run against your take-home | |||||||
| The affordability calculation that actually matters: (P&I + taxes + insurance + HOA + $500 maintenance reserve) ÷ monthly take-home pay. If this exceeds 40–45%, you are likely entering house-poor territory. | |||||||||

| $300,000 | $7,000/mo | ~$1,050,000 | ~$990,000 (with PMI) | Jumbo loan territory; most markets accessible | |||||
| Home price estimates use 28% of gross income as the monthly payment (P&I + taxes + insurance), with approximate national average tax and insurance amounts. Actual payment will vary significantly by state (NJ, IL, TX have high property taxes; FL, TX have no state income tax). Always calculate for your specific market and income situation. | |||||||||
The House-Poor Warning Signs
| Warning Sign | What It Means |
|---|---|
| Housing + debt payments exceed 45% of take-home | Minimal margin for savings, emergencies, or unexpected costs |
| You are contributing less than 10% to retirement to afford the payment | Trading long-term wealth for housing; a serious long-term cost |
| You have no maintenance reserve in the budget | First major repair (HVAC, roof, plumbing) causes financial stress |
| You stretched for a larger home than you need because "it's an investment" | The excess square footage costs money every month without adding proportional value |
| The only way you can afford it is with a 2-income household with no margin | Any income disruption (job loss, illness, new child) creates immediate housing crisis |
“The most useful thing I tell buyers about affordability is the difference between what the bank approves and what you should spend. A lender who approves you at $600,000 is not telling you that $600,000 is the right number. They're telling you that you qualify. The right number is the one where you can make the payment comfortably, fund your retirement, maintain a 3–6 month emergency fund, budget for maintenance, and still have a life. That number is often 10–25% below what the bank approves. Buy up to the comfortable number, not the approved number.”

How much house can I afford on my salary?
The 28/36 guideline: housing (PITI) should not exceed 28% of gross monthly income. On $100,000/yr: gross monthly = $8,333; 28% = $2,333/mo housing; roughly $350,000 purchase at 6.5% with 20% down. But check against take-home: if take-home is $5,600/mo, $2,333 is 41.7% of actual spendable income. Add maintenance ($500/mo) and you're at 50%. The comfortable number is often 10–25% below what the bank approves.
What is the 28/36 rule?
Front-end: total housing costs (PITI + HOA) should not exceed 28% of gross monthly income. Back-end: all monthly debt payments combined should not exceed 36% of gross income. This is a guideline, not a law. Lenders allow up to 43–50% DTI. The 28/36 rule represents a conservative, comfortable level that leaves room for savings, emergencies, and retirement contributions.
Can I afford a house if I am house poor?
Technically yes if you make the payment, but house poor is a real financial condition. Signs: housing costs exceed 40–45% of take-home; cutting retirement contributions to afford the mortgage; no maintenance reserve; one income disruption away from crisis. House poor buyers often sell within 3–5 years at a loss after transaction costs — the worst of both worlds.
How do lenders calculate how much you can borrow?
Primarily through debt-to-income ratio (DTI): all monthly debt payments ÷ gross monthly income. Most conventional lenders allow up to 43–45% DTI; FHA up to 56.9%; some lenders up to 50% with compensating factors. They also check credit score, assets, employment history, and down payment size. Lender approval is not the same as financial comfort. The approved amount is the maximum; the comfortable amount is what you should target.
