How Much House Can I Afford? (2026 Complete Guide)
A lender telling you what you qualify for is very different from what you can comfortably afford. Our 2026 Home Affordability Calculator uses the Consumer Financial Protection Bureau (CFPB) Debt-to-Income guidelines to determine your true maximum budget - without making you "house poor." Enter your gross income, monthly debts, and down payment to see your conservative and maximum home price in seconds.
The 28/43 Rule: How Lenders Measure Affordability
Most mortgage lenders and the CFPB use two Debt-to-Income (DTI) ratios to evaluate how much house you can afford. Understanding both is essential before you start shopping:
- Front-End DTI (the "28% Rule"): Your total monthly housing costs - principal, interest, property taxes, homeowners insurance, HOA fees, and PMI - should not exceed 28% of your gross monthly income (before taxes). This is the classic housing ratio used by conventional lenders.
- Back-End DTI (the "43% Rule"): Your housing payment plus all other monthly debt obligations (car loans, student loans, credit card minimums, alimony, child support) should not exceed 43% of gross income. Per the CFPB, 43% is generally the maximum back-end DTI allowed for a Qualified Mortgage.
Conservative vs. Aggressive Budget: Using the maximum 43% back-end DTI means nearly half of your pre-tax income goes immediately to debt and housing - before groceries, childcare, retirement, or emergencies. Our calculator shows both scenarios: a conservative budget (closer to 28% front-end) and an aggressive budget (up to 43% back-end) so you can decide where you are comfortable.
Home Affordability Example: $100,000 Income
Here is how the math works using a $100,000 annual salary ($8,333/month gross) at a 7% 30-year fixed rate with a 10% down payment and $500/month in existing debts:
| Budget Type | Max Monthly Housing | Max Home Price (est.) |
|---|
| Conservative (28% front-end) | $2,333/mo | ~$285,000 |
| Moderate (36% back-end) | $2,500/mo | ~$310,000 |
| Aggressive (43% back-end) | $3,083/mo | ~$385,000 |
Note that the aggressive scenario assumes your existing $500/month in debts leaves $3,083/month available for housing (43% × $8,333 − $500). This table is illustrative - use our calculator for your exact numbers based on your local property taxes and insurance rates.
Key Factors That Shift Your Maximum Home Price
Even small changes to any of these inputs can dramatically move your affordable price range up or down:
- Interest Rate: Every 1% increase in the mortgage rate reduces how much you can borrow by roughly 10%. At 6%, a $2,333/month P&I payment supports a ~$390,000 loan. At 7.5%, the same payment only supports ~$330,000.
- Existing Monthly Debts: Eliminating a $400/month car loan instantly frees up that cash for housing - which translates to roughly $50,000-$60,000 more in purchasing power at 7%.
- Down Payment Amount: A larger down payment shrinks the loan, reduces or eliminates PMI (if 20%+), and can push you into a better rate tier. Going from 5% down to 20% down on a $350,000 home saves ~$150/month in PMI and lowers the loan amount by $52,500.
- Property Tax Rate: Property taxes vary enormously by location. New Jersey averages over 2% of home value annually, while Hawaii averages under 0.3%. On a $400,000 home, that's the difference between $667/month and $100/month in taxes - a $567/month swing that directly affects how much loan you can carry.
- HOA Fees: Condos and planned communities often charge $200-$600/month in HOA dues. These are included in your front-end DTI calculation, which directly reduces the loan amount you can support.
2026 Loan Limits: FHA, Conforming, and Jumbo
The loan category you fall into depends on your calculated home price and local limits set annually by the Federal Housing Finance Agency (FHFA) and HUD (for FHA limits):
- FHA Loan (2026 floor: $541,287): Best for first-time buyers with credit scores of 580+ and as little as 3.5% down. FHA loans carry mandatory mortgage insurance premium (MIP) for the life of the loan if your down payment is under 10%.
- Conforming Conventional (2026 baseline: $832,750): The standard loan backed by Fannie Mae and Freddie Mac. Requires a minimum 620 credit score; best rates at 740+. PMI is cancellable once you reach 20% equity, unlike FHA MIP.
- High-Cost Conforming (up to $1,249,125): Parts of California, New York, Hawaii, and Alaska qualify for higher conforming limits. Check the FHFA county-level lookup tool for your specific area.
- Jumbo Loan (above conforming limit): If your calculated max home price pushes the loan above the conforming ceiling, you enter jumbo territory. Jumbo loans require excellent credit (typically 720+), 10-20% down, and significant cash reserves - often 12 months of payments.
How Your Credit Score Affects Affordability
Your credit score does not just determine whether you qualify for a loan - it directly controls the interest rate you receive, which controls how much house you can afford. Here is how FICO tiers map to typical conventional mortgage rates and monthly payments on a $350,000 loan:
| Credit Score Range | Typical Rate | Monthly P&I ($350K) |
|---|
| 760-850 (Exceptional) | ~6.50% | ~$2,213 |
| 700-759 (Good) | ~6.85% | ~$2,296 |
| 660-699 (Fair) | ~7.25% | ~$2,388 |
| 620-659 (Minimum conventional) | ~7.75% | ~$2,506 |
A 760+ score versus a 620-659 score on a $350,000 loan saves ~$293/month - over $105,000 over the life of a 30-year mortgage. You can check your credit score for free at AnnualCreditReport.com (federally mandated, no credit card required).
First-Time Buyer Programs That Improve Affordability
If standard affordability limits feel out of reach, these programs can meaningfully change the math:
- FHA Loan (3.5% down, 580+ score): The most widely used first-time buyer program. Allows gift funds for the entire down payment. The trade-off is mandatory MIP for the life of the loan.
- Fannie Mae HomeReady / Freddie Mac Home Possible (3% down): Conventional loans with reduced PMI for low-to-moderate income buyers. Income limits apply (typically 80% of Area Median Income). See our Government Loan Comparison Calculator to compare.
- VA Loan (0% down, no PMI): For eligible veterans, active-duty service members, and surviving spouses. No down payment required and no monthly PMI - the most powerful affordability tool for those who qualify.
- USDA Rural Development Loan (0% down): For buyers in eligible rural and suburban areas. No down payment, competitive rates, and an annual guarantee fee that is much lower than FHA MIP. Check eligibility at USDA Rural Development.
- State and Local Down Payment Assistance (DPA): Most states offer grants or forgivable second mortgages for first-time buyers. The HUD local homebuying programs directory lists programs by state.
Next Steps After Calculating Affordability
- Get a mortgage pre-approval. Once you know your target price range, a lender pre-approval confirms what a real institution will actually lend you, locks in a rate for 60-90 days, and strengthens your offer in competitive markets.
- Calculate your full monthly payment. Run your specific home price, down payment, and ZIP code through our Full PITI Mortgage Calculator to get the exact all-in monthly cost including taxes, insurance, and PMI.
- Build your down payment plan. Our Down Payment Savings Planner shows exactly how many months it will take to reach 3%, 10%, or 20% down given your current monthly savings rate.
- Estimate closing costs. Closing costs typically add 2%-5% on top of your down payment. Use our Closing Costs Calculator to budget every fee by state before you make an offer.
- Compare loan types. See whether FHA, VA, USDA, or a conventional loan gives you the lowest total cost for your credit profile using the Government Loan Comparison Calculator.
