How Much House Can I Afford on $100k a Year?

By the SimpleCalc Mortgage Editorial Team · Updated August 2026 · 5 min read · Affordability

On a $100,000 salary, most buyers can realistically afford a home in the $300,000–350,000 range — but that number swings a lot based on your existing debts, your down payment, and your local property taxes. Here's how that estimate is built, and how to find your real number.

The quick answer at $100,000/year

Gross monthly income: $8,333
28% rule — max housing payment: $2,333/month
Principal & interest portion (7%, 30yr): ~$1,880/month
Estimated home price: $300,000–350,000
Comfortable target (25% of income): about $2,083/month

How this number is calculated

Lenders use the 28/36 rule. Your total housing payment — principal, interest, property taxes, insurance, and any PMI or HOA — should stay under 28% of your gross monthly income. All your debts combined should stay under 36%. On $100,000, that 28% ceiling works out to about $2,333 a month for housing. After setting aside roughly $300–450 for taxes and insurance, the rest supports the loan itself.

What a $100k income realistically buys

A six-figure income buys a comfortable home in the large majority of U.S. markets and remains viable even in higher-cost metros. The main constraints at this income are usually existing debt (car loans, student loans) and local property taxes rather than the income itself.

Your existing debts change this more than anything

The single biggest variable isn't your income — it's what you already owe. Every $400/month car payment cuts the mortgage you qualify for by roughly $55,000–$65,000. Two car payments plus a student loan can erase six figures of buying power before you apply. If the $$300,000–350,000 range feels high for your situation, existing debt is usually why — and paying it down is the fastest way to raise what you can afford.

The lender's maximum isn't your target. A bank may approve you above the 28% line, but approval isn't the same as comfortable. Aim for the $2,083/month "comfortable" figure — about 25% of income — so the mortgage leaves room for savings, maintenance, and the rest of your life.

FHA vs. conventional at this income

At $100,000, conventional financing is almost always the right call — you'll clear DTI requirements easily and benefit from removable PMI. FHA rarely makes sense here unless credit is the limiting factor.

Frequently asked questions

How much house can I afford on $100,000 a year?
Roughly $2,333/month toward housing under the 28% rule, supporting about a $300,000–350,000 home at 7% over 30 years — more with a larger down payment, less with significant existing debt.

Is $100,000 a good salary to buy a house?
Yes, in most of the country it's a strong position. Where it gets tight is expensive coastal metros with high prices and high property taxes — there, $100,000 may only reach a modest home or condo.
