How Much House Can I Afford in 2026?

Most first-time buyers approach this question backwards.

They find a home they love, then hope the numbers work out. Sometimes they do. More often, they don’t — and the buyer ends up either overextended or heartbroken.

The smarter move is to figure out your number before you ever set foot in an open house. Not because budgeting is fun, but because knowing what you can genuinely afford puts you in control of the process instead of at the mercy of it.

There’s one distinction worth making right at the start: what a lender will approve you for and what you can comfortably afford are often two very different numbers. Lenders calculate maximum borrowing capacity. You have to calculate what actually fits your life. This guide walks through both.

How Lenders Decide What You Qualify For

When a lender evaluates your application, they’re looking at a handful of key numbers. Understanding those numbers before you apply means no surprises.

Your debt-to-income ratio (DTI) is the most important one.

This is the percentage of your gross monthly income that goes toward debt payments. To calculate it yourself, add up all your monthly debt obligations — student loans, car payments, credit cards, any existing loans — and divide that total by your gross monthly income. Most conventional lenders want your back-end DTI (which includes your future mortgage payment) at or below 43%, though some loan programs allow higher with strong compensating factors.

Your credit score shapes your interest rate — which shapes everything else.

The difference between a 6% and a 7% rate on a $400,000 mortgage is roughly $260 per month. Over 30 years, that’s more than $93,000. Most lenders use 620 as a practical floor, though Fannie Mae and Freddie Mac now evaluate your full financial picture rather than applying a strict cutoff. The higher your score, the better your rate and the more purchasing power you have.

Your down payment determines both your loan size and whether you’ll pay PMI.

Putting down less than 20% on a conventional loan triggers private mortgage insurance, which typically runs 0.3% to 1.5% of the loan amount annually. On a $400,000 loan, that’s anywhere from $100 to $500 added to your monthly payment. It’s not a dealbreaker — but it’s a real cost, and one that catches a lot of first-time buyers off guard.

Lenders also want to see stable income — typically two years of consistent employment history.

Gaps, recent job changes, or self-employment income all require additional documentation and can complicate approval. If any of those apply to you, it’s worth talking to a lender early so you know what to expect.

What Your Monthly Payment Actually Looks Like

Here’s where buyers consistently underestimate. You see the mortgage payment and assume that’s your number. It isn’t.

Your true monthly housing cost has several components beyond principal and interest, and all of them matter.

Property taxes are bigger than most people expect — and they vary wildly by location.

The national average effective property tax rate sits around 1.01%, though rates range from 0.28% in Hawaii to over 2% in New Jersey and Illinois. CountryTaxCalc On a $429,000 home at the national average, that’s roughly $360 per month baked into your escrow payment. In a high-tax state, it could easily be double that. Where you buy matters as much as what you buy.

Homeowners insurance is required by every mortgage lender, and costs have been climbing.

The national average runs about $2,543 per year for $300,000 in dwelling coverage — around $212 per month — though Florida homeowners pay an average of $7,136 annually, while Hawaii homeowners pay as little as $659.

HOA fees, if the home has them, can range from negligible to budget-busting.

About 44% of homes for sale in 2025 carried HOA fees, with a national median around $135 per month. U.S. News & World Report But that median hides a wide range. A suburban single-family HOA might charge $75 a month for landscaping and a pool. A condo in a coastal city can run $600 or more. If you’re buying in an HOA community, request the financials before you make an offer — not after.

Put it all together, and the real number looks different from the headline payment.

Take a $429,000 home with 10% down on a 30-year fixed mortgage at today’s rate of around 6.4%. Your principal and interest payment is roughly $2,420 per month. Add average property taxes ($360), homeowners insurance ($212), and PMI at around 0.8% ($238), and your true monthly cost is closer to $3,230 — before any HOA fees. That’s the number you need to stress-test against your budget.

What You Qualify for vs. What You Can Actually Afford

This is the conversation most lenders won’t have with you — because it isn’t their job.

Their job is to calculate maximum eligibility. Your job is to figure out what actually works for your life.

The standard guideline most financial planners use is the 28/36 rule: spend no more than 28% of your gross monthly income on housing costs (principal, interest, taxes, and insurance), and no more than 36% on total debt. Some lenders will approve you at a 43% DTI or higher. That doesn’t mean you should borrow to that limit.

The gap between approved and comfortable is real — and worth taking seriously.

If your lender approves you for $500,000 but your honest budget says $380,000 feels right, buy at $380,000. The monthly savings go toward retirement, your emergency fund, the repairs you’ll need when something breaks. And something always breaks.

A few questions worth sitting with before you settle on a number:

• Does your income feel stable, or could it shift in the next few years?
• Do you have three to six months of expenses in an emergency fund — separate from what you’re putting toward the down payment?
• Are there big costs on the horizon — a car replacement, a baby, a career change — that will compete with a higher mortgage payment?

Lenders don’t ask these questions. You have to ask them yourself.

The Costs Most Buyers Forget

Owning a home comes with a category of costs that renting doesn’t — and first-time buyers almost always underestimate them.

Maintenance and repairs are the biggest blind spot.

The rule of thumb is to budget 1% of your home’s value per year. On a $429,000 home, that’s roughly $4,300 annually, or about $358 per month set aside. Some years you’ll spend nothing. The year the roof goes or the HVAC dies, you’ll spend far more. Older homes and homes in harsh climates warrant budgeting higher.

Closing costs are due at closing, in addition to your down payment.

They typically run 2–5% of the loan amount — on a $429,000 purchase, expect to bring $8,500 to $21,000 to the table beyond what you’ve saved for the down payment. These aren’t optional, and they can’t usually be rolled into the loan on a purchase.

Moving costs, immediate updates, and furnishings catch almost everyone off guard.

Even if you’re being conservative, budget a few thousand dollars for the transition. The first month of homeownership is rarely cheap.

The buyers who end up house-poor aren’t usually the ones who bought too much house by a lot. They’re the ones who bought at the very top of what they qualified for, didn’t account for taxes and insurance, skipped the maintenance reserve, and then had a $6,000 HVAC emergency six months in. The math was never in their favor. They just didn’t run the real math before they bought.

How to Find Your Number

Start with your gross monthly income and multiply by 0.28. That’s the maximum you should spend on housing costs according to the conservative rule.

Then work backwards from that number. Plug in current interest rates, your expected down payment, and real local estimates for property taxes and insurance. That tells you the home price that keeps you at or below that monthly ceiling.

If that number is lower than you were hoping for, that’s useful information — not a dead end. It means you either need more time to save a larger down payment, work on your credit score to get a better rate, or look in a different price range or market.

None of those are failures. They’re decisions you’re far better off making now than after you’ve signed a purchase agreement.

The Bottom Line

There’s no universal answer to how much house you can afford, because affordability is personal in a way a lender’s formula can’t capture.

What a lender approves is a ceiling, not a recommendation.

The right number is the one where you can make the payment comfortably, maintain the home properly, keep your emergency fund intact, and still feel financially secure. Not the number that maxes out your pre-approval letter.

Figure that out before you start shopping. Everything else gets easier from there.
