How much house can I afford on a $100,000 salary?

Using the 28/36 rule, a $100,000 salary ($8,333/mo gross) gives you a max housing payment of $2,333 (28%). At a 6.5% rate with 10% down and typical taxes/insurance, that works out to a home price around $310,000–$350,000. That number shrinks if you have car loans, student debt, or credit card payments. Your actual comfortable number is probably closer to $280,000–$320,000 once you factor in maintenance, utilities, and not wanting to be house poor.

Is 2026 a good time to buy a house with rates at 6.5%?

It depends on your timeline. Rates at 6.5% are high compared to the 3% era but below the 8% peak of late 2023. If you plan to stay in the home 7+ years, buying today locks in your payment while rents keep rising. The flip side: inventory is still tight at 4.4 months supply (a seller's market), and existing home sales are up just 0.2% month over month. If you can find a home under $400,000 in a good school district with a 10–15% down payment, 2026 is workable. If you are stretching to the max approval amount at 6.5%, wait and save more.

How much should I put down on a house in 2026?

Put down 20% if you have the cash — it eliminates PMI (saving 0.5% to 1.5% of the loan value annually) and makes your offer more competitive in a bidding war. For first-time buyers, 5–10% is realistic. FHA loans allow 3.5% down but come with higher insurance premiums. With the median home at $417,700, a 10% down payment is $41,770; at 20% it is $83,540. The right number balances your monthly payment comfort with your savings goals.

What's the 28/36 rule and does it still apply?

The 28/36 rule says spend no more than 28% of gross monthly income on housing costs (PITI) and no more than 36% on total debt. It still applies as a lender guideline for conventional loans, but many buyers in high-cost markets push past it. A safer personal rule in 2026 is 25% for housing given higher property taxes, insurance, and maintenance costs compared to a decade ago. If your debt-to-income ratio exceeds 36%, lenders will raise your rate or deny the loan.

How Much House Can You Afford? 2026 Home Buying Guide

March 12, 2026 · By Alex Chen

Spring home buying season is here, and the question every buyer is asking: how much house can I actually afford in 2026? Your pre-approval letter from the bank might say $500,000-plus, but that number is designed to maximize their interest income, not protect your financial future. This guide walks you through the real numbers using current market data so you can shop with confidence.

The 2026 Housing Market: Where We Stand

Before we talk about your personal budget, here is the landscape as of June 2026:

30-year fixed mortgage rate: ~6.48–6.53% (Freddie Mac Primary Mortgage Market Survey)
15-year fixed rate: ~5.87–5.96%
Median existing home price: $417,700 (National Association of Realtors, April 2026) — the 34th consecutive month of year-over-year price increases
Existing home sales: 4.02 million SAAR, up 0.2% month over month
Inventory: 1.47 million units, 4.4 months supply. For context, a balanced market is 5–6 months. We are still in a seller's market.
Homeownership rate: 65.3%
Purchase demand: 20% above a year ago per Freddie Mac (April 2026)

NAR Chief Economist Lawrence Yun noted that "home sales are being boosted by rates decreasing from recent highs and income growth outpacing price gains." That is cautiously optimistic for buyers — but inventory remains tight, which means bidding wars are still common in desirable school districts and metro areas.

The 28/36 Rule — and When to Break It

Lenders use the 28/36 rule to qualify you for a mortgage. Your monthly housing costs (principal, interest, taxes, insurance — PITI) should stay under 28% of your gross monthly income. Your total debt payments (housing plus car loans, student loans, credit cards) should stay under 36%.

Here is what that looks like on a $100,000 salary ($8,333/month gross):

Max housing payment (28%): $2,333/month
Max total debt (36%): $3,000/month
With $500/month in existing debts, you have $2,500 left for housing

At a 6.5% rate with 10% down and typical taxes and insurance, that $2,333 payment gets you roughly a $310,000–$350,000 home. Notice how far that is from what a lender might pre-approve you for? That is the gap between approved and comfortable.

My take: In 2026 with property taxes up and insurance rates climbing in many states, I would target 25% of gross income for housing rather than 28%. You need room for maintenance (budget 1–2% of home value annually), rising utility costs, and frankly, a life that is not 100% mortgage payments.

Down Payment: How Much in 2026?

The standard advice is 20% down to avoid private mortgage insurance (PMI). With the median home at $417,700, that means $83,540. That is a lot of cash — and most first-time buyers do not have it.

Here are your realistic options in 2026:

3% down (conventional first-time buyer programs): $12,531 on the median home. You will pay PMI (0.5–1.5% of the loan annually) until you reach 20% equity.
5–10% down: $20,885–$41,770. A sweet spot for many buyers. At 10% down with good credit, your PMI will be on the lower end of that range.
20% down: $83,540. No PMI, stronger offer, instant equity. Worth it if you can swing it.

On PMI: A 1% PMI rate on a $375,930 loan (10% down on median home) adds $3,759 per year — $313 per month. That is real money. But it is temporary. Once you hit 20% equity, it drops off. (Data source: Bankrate, Freddie Mac)

The Hidden Costs Most First-Time Buyers Miss

The purchase price is just the entry fee. Here is what ownership actually costs per month beyond the mortgage:

Property taxes: 0.5–2.5% of home value annually depending on your county
Homeowners insurance: $900–$1,800/year, higher in wildfire, flood, or hurricane zones
Maintenance and repairs: Budget 1–2% of value annually. On a $400,000 home, that is $4,000–$8,000/year or $333–$667/month
HOA fees: $150–$500+/month in planned communities and condos
Utilities: Expect 20–40% more than your apartment — you are heating and cooling more square footage

Add it up and a $2,333 PITI payment can easily become a $3,200–$3,500 total monthly housing cost. That is 38–42% of gross income on a $100K salary. Too high in my opinion. This is why your comfortable purchase price is usually lower than what the bank approves.

Know Your Take-Home Pay First

Start with after-tax income, not gross. Your net pay after federal, state, FICA, and deductions is what actually hits your bank account each month. Use CalcInstant's salary calculator to see your real monthly income, then work backward from there.

Mortgage Payment Breakdown — What $2,333 Actually Buys

At a 6.5% rate on a $315,000 loan (30-year fixed), your principal and interest payment is $1,991. Add $350/month for taxes, $100/month for insurance — we are at $2,441. Add PMI if you put down less than 20% and you are pushing $2,700. That gets you a home around $350,000. At 6.5%, the interest alone in the first year is roughly $20,400. Rate matters.

The 15-year fixed at ~5.9% gives you a lower rate but a much higher payment. On that same $315,000 loan, your P&I jumps to about $2,640/month before taxes and insurance. The upside: you build equity fast and pay $188,000 less in total interest over the life of the loan.

Run Different Scenarios with the Mortgage Calculator

CalcInstant's mortgage calculator lets you test every variable — home price, down payment, rate, term, taxes, insurance, PMI — and see the full monthly payment instantly. Try the 30-year versus 15-year, or see what happens if rates move 0.25% in either direction.

Buying vs. Renting in 2026

Here is the honest truth: renting is not "throwing money away" when mortgage rates are 6.5% and prices are still climbing. If your rent is $1,800/month and the equivalent mortgage (with taxes, insurance, maintenance) is $3,200/month, you are better off renting and investing the $1,400/month difference in the market — assuming you invest it and do not spend it.

But if you find a home in the $300K–$350K range where the all-in monthly cost is within 20% of local rent, buying makes sense long term. Your payment stays flat (except taxes/insurance creep), and rents go up 3–5% most years. Over 7 years, that gap closes.

Why Your Pre-Approval Number Is a Trap

Lenders pre-approve you for the maximum they think you can repay. They do not care if you want to save 15% for retirement, travel, have kids, or ever take a vacation. In 2026, with rates where they are, borrowing the max pre-approval amount at 6.5% is a fast track to being house poor.

A more realistic rule: target a home no more than 2.5–3 times your annual household income. On $100K/year, that is $250,000–$300,000. On $150K, it is $375,000–$450,000. This keeps your monthly payment manageable even if one earner loses a job or rates stay elevated at renewal.

Once you have your realistic price range, use the Mortgage Calculator to compare down payment scenarios, test different rates, and find a payment you can sleep soundly on — before you step into a single open house.
