How Much House Can I Afford on a $100K Salary in 2026?

Earning $100,000 puts you in a strong position to buy a home, but the answer to "how much house" depends on several factors beyond just your salary. Let's break down the real numbers.

The Quick Answer

On a $100K salary with no other debt, you can typically afford a $350,000 to $450,000 home, depending on your down payment, interest rate, property taxes, and other debts. With current mortgage rates around 6.5-7%, the sweet spot for most $100K earners is in the $380,000-$420,000 range.

The 28/36 Rule

Lenders use two key ratios. The front-end ratio (28%): your total housing payment should not exceed 28% of gross monthly income. On $100K, that's $8,333/month gross, so maximum housing payment = $2,333/month. The back-end ratio (36%): total debt payments (housing + car + student loans + credit cards) should stay under 36% = $3,000/month.

Real Numbers at Different Down Payments

With a 20% down payment at 6.75% rate: you can afford approximately $420,000 home ($84,000 down, $2,180/month PITI). With 10% down: approximately $370,000 ($37,000 down, $2,310/month including PMI). With 5% down: approximately $340,000 ($17,000 down, $2,340/month including PMI). The key takeaway: a larger down payment dramatically increases your purchasing power by eliminating PMI and reducing the loan amount.

What Most People Forget

The mortgage payment is just the beginning. Budget an additional $300-600/month for: property taxes (varies hugely by state — $150-$500/month), homeowner's insurance ($100-$200/month), maintenance and repairs (1% of home value annually = $350/month on a $400K home), utilities (typically $100-200 more than renting). These hidden costs mean your "affordable" $420,000 home actually requires $2,800-$3,000/month in total housing costs.

How Existing Debt Changes Everything

If you have a $400/month car payment and $300/month student loan, your available housing budget drops from $2,333 to about $1,633/month (applying the 36% back-end ratio). That reduces your home budget from $420,000 to roughly $280,000. Paying off debt before buying isn't just good advice — it literally increases how much home you can afford by tens of thousands of dollars.
