The answer depends on more than just your income. Here's what lenders look at — and how to find your real number.
With mortgage rates still elevated in 2026, buying a home requires more planning than ever. Many buyers make the mistake of shopping for homes before knowing what they can truly afford — then falling in love with something out of their range, or worse, stretching too far and becoming "house poor." This guide walks you through the real math lenders use to determine how much home you can afford.

The most widely cited affordability guideline is the 28/36 rule. It states:
Example: If your gross household income is $8,000/month, the 28/36 rule suggests your housing payment should stay at or below $2,240/month, and your total debt payments below $2,880/month.
At a 7% mortgage rate with 20% down, a $2,240 monthly payment corresponds to roughly a $280,000–$300,000 purchase price (before taxes and insurance).
In practice, most lenders use your debt-to-income ratio (DTI) to determine how much they'll lend you. Your DTI is simply your total monthly debt payments divided by your gross monthly income.
Most conventional lenders want your DTI at or below 43%, though some lenders go up to 50% in certain situations. FHA loans often allow up to 57% in some cases.
Lenders want stable, documentable income. W-2 employees typically need 2 years of employment history. Self-employed buyers need 2 years of tax returns showing consistent income. Side income may count if it's been consistent for 2+ years.
Your credit score directly affects the interest rate you qualify for — and that affects your monthly payment and total cost dramatically.
On a $300,000 loan, the difference between a 620 credit score and a 760 score can be over $100/month in payment — and $36,000+ over the life of the loan.
A larger down payment reduces your loan amount and eliminates PMI (private mortgage insurance) if you hit 20%. PMI typically costs 0.5%–1.5% of the loan amount annually — on a $300,000 loan, that's $1,500–$4,500/year added to your costs.
Most lenders want to see that you'll have 2–6 months of mortgage payments in savings after closing. This proves you can weather financial disruptions without defaulting.
Lenders prefer at least 2 years with the same employer or in the same field. Recent job changes aren't necessarily disqualifying — especially if you moved to a higher-paying role in the same industry.
One of the biggest surprises for first-time buyers is how much homeownership costs beyond the mortgage payment. Many people budget only for PITI (principal, interest, taxes, insurance) and get blindsided by ongoing costs they never considered. Here are the most commonly missed expenses:
Budget 1%–2% of your home's value per year for maintenance and repairs. On a $350,000 home, that's $3,500–$7,000 annually — roughly $300–$580 per month. This money funds things like roof repairs, HVAC servicing, plumbing issues, appliance replacements, and ongoing upkeep. Older homes (30+ years) often land closer to the 2% end. Brand-new construction may be lower in early years but can spike after warranty periods expire.
Closing costs typically run 2%–5% of the purchase price. On a $350,000 home, that's $7,000–$17,500 paid upfront at closing, in addition to your down payment. These include lender origination fees, title insurance, appraisal, attorney fees (in some states), prepaid interest, and escrow setup for taxes and insurance. Many first-time buyers are surprised to learn they need significantly more cash than just their down payment.
If your home is in a community with a homeowners association, monthly HOA fees can range from $100/month for a basic neighborhood to $800+/month in luxury condo buildings. HOAs also have the power to levy special assessments — one-time charges for major community expenses like roof replacement or pool renovation. Before buying, review the HOA's financials to ensure it's adequately funded and not on the verge of a major assessment.
Owned homes are often larger than rented apartments, which means higher utility bills. If you're moving from a 900-square-foot apartment to a 2,200-square-foot house, expect utility costs to roughly double. Ask the seller for the last 12 months of utility bills — most will provide them, and it gives you a realistic picture of ongoing costs.
Lawn care, snow removal, gutter cleaning, exterior painting, driveway sealing — these are real, recurring costs that apartment dwellers never face. Even a modest landscaping budget of $100–$200/month adds $1,200–$2,400 to your annual homeownership cost.
Your credit score doesn't just affect whether you qualify — it dramatically affects your interest rate, and therefore how much house you can realistically afford within a given monthly payment budget.
| Credit Score Range | Estimated Rate (30yr Fixed, 2026) | Monthly Payment (on $300k loan) | Total Interest Paid |
|---|---|---|---|
| 760–850 | 6.5% | $1,896 | $382,560 |
| 720–759 | 6.75% | $1,945 | $400,200 |
| 680–719 | 7.25% | $2,047 | $436,920 |
| 640–679 | 7.75% | $2,152 | $474,720 |
| 600–639 | 8.5% | $2,307 | $530,520 |
The difference between a 760+ score and a 640–679 score is over $250/month — and nearly $100,000 over the life of the loan. If your score is below 720, spending 6–12 months improving it before applying for a mortgage could save you tens of thousands of dollars. Focus on paying down revolving credit card balances and resolving any collection accounts or late payments.
Mortgage points (also called discount points) let you pay upfront cash at closing to "buy down" your interest rate. One point equals 1% of your loan amount and typically reduces your rate by 0.25% — though the exact reduction varies by lender and market conditions.
Paying points makes sense only if you keep the loan long enough to recoup the upfront cost through monthly savings. The calculation:
If you plan to stay in the home 10+ years, paying points is likely worth it. If you might sell or refinance within 3–4 years, skip the points and keep the cash. In a refinance environment, many buyers also skip points knowing they may refinance when rates drop.
These terms get used interchangeably, but they're meaningfully different — and sellers care about the distinction.
Pre-qualification is an informal estimate from a lender based on unverified information you provide. You tell them your income, debts, and assets; they give you a rough ballpark of what you might qualify for. No credit pull, no document verification. It takes 10–15 minutes and means very little to a serious seller.
Pre-approval involves a real credit check and document verification — tax returns, pay stubs, bank statements. The lender actually underwriters your basic financial profile and issues a conditional commitment letter. This is what sellers and their agents actually want to see with an offer. In competitive markets, making an offer without pre-approval often gets you ignored.
Some lenders now offer "verified approval" or "credit approval" — a full underwrite before you even find a property, with only the property appraisal remaining. This is the strongest signal of creditworthiness you can show a seller and can make your offer nearly as strong as a cash offer in some situations. If you're in a competitive market, ask your lender if they offer this option.
The 2022–2024 rate environment fundamentally changed home affordability. Rates went from the 3% range in 2021 to 7%+ by 2023–2024, and while they've moderated somewhat in 2026, they remain significantly higher than the pandemic-era lows that many buyers got accustomed to.
A $400,000 home with 20% down ($320,000 loan):
That's an extra $674/month compared to the 2021 low — or $8,088/year. For many buyers, this means qualifying for a significantly smaller loan than they might have expected based on older mental models. To afford the same monthly payment at 6.5% as at 3%, buyers would need to purchase a home nearly 30% cheaper.
Many buyers in 2025–2026 are using this philosophy: buy the home you want now at current prices, accepting today's rate, with a plan to refinance when and if rates drop. The risk: rates may not drop substantially. The logic: if you wait for rates to drop, so does everyone else, and competition and prices surge. Whether this strategy makes sense depends on your specific market, timeline, and financial cushion.
The "renting is throwing money away" argument is far too simplistic. The real rent vs. buy analysis depends on several factors:
⚠️ Being "house poor" is real. Just because a lender approves you for a certain amount doesn't mean you should borrow that much. Many buyers use 100% of their approved limit and then struggle to afford vacations, emergencies, or retirement savings. Consider staying 10–15% below your maximum approval.

Try the Free Mortgage Calculator →The traditional guideline is no more than 28% of your gross monthly income on housing costs (PITI — principal, interest, taxes, insurance). In practice, many financial advisors suggest keeping it below 25% of take-home (after-tax) pay to leave room for other financial goals like retirement savings, emergency fund, and life expenses. These are guidelines, not laws — someone with no other debt and high savings can sustainably spend more; someone with student loans and car payments may need to spend less.
Yes. Conventional loans allow as little as 3% down for first-time buyers, FHA loans allow 3.5% down with a credit score of 580+, and VA loans (for veterans) allow 0% down. The trade-off: less than 20% down on a conventional loan requires PMI (private mortgage insurance), adding $100–$400+/month to your payment. FHA loans include their own mortgage insurance premium regardless of down payment amount. Many buyers prioritize getting into a home faster and accept PMI, planning to remove it once they hit 20% equity.
The minimum varies by loan type: conventional loans typically require 620+; FHA loans accept as low as 500 (with 10% down) or 580 (with 3.5% down); VA and USDA loans have no official minimum but most lenders require 620+. However, the minimum to qualify is very different from the score you need for good rates. Aim for 720+ to access competitive rates. A few months of focused credit improvement (paying down card balances, fixing errors) can make a meaningful difference.
Your target savings should cover: down payment (3–20% of purchase price), closing costs (2–5% of purchase price), moving expenses ($1,000–$5,000+), immediate repairs/updates, and a post-closing emergency fund of 3–6 months of housing costs. On a $350,000 home with 10% down, plan for $35,000 down + $8,750–$17,500 closing costs + $5,000+ emergency reserve = roughly $50,000–$60,000 total before you're comfortable closing.
Nobody can reliably predict when rates will drop, or by how much. If you plan to stay 5+ years, can comfortably afford today's payment, and have found a home that meets your needs, buying now and refinancing later if rates drop is a reasonable strategy. If the current payment would be a stretch, or you're not sure you'll stay long-term, waiting and continuing to save makes sense. Avoid buying at the absolute limit of what you can afford based on hope that rates will improve soon.
The monthly payment is what you live with every month, so it's the more immediately relevant number. But the purchase price matters for long-term wealth — your equity builds based on the purchase price, not the payment. A lower interest rate on a more expensive home can produce the same monthly payment as a higher rate on a cheaper home, but the more expensive home gives you more asset appreciation potential (and also more downside risk if prices fall). Look at both numbers together.
How much house you can afford depends on your income, credit score, existing debt, down payment, and the full cost of ownership — not just the purchase price. The 28/36 rule is a good starting point, but your lender's DTI requirements will set the actual ceiling. And remember: being approved for a loan amount doesn't mean you should spend that much. The most financially successful homeowners typically buy below their maximum — and use the breathing room to build wealth in other ways.
