How Much House Can I Afford on a $100,000 Salary?

A $100,000 salary is one of the most common income levels people search around when they start house hunting, and for good reason: it's the point where "six figures" starts to feel like real buying power. Under the standard lending math, that income supports a home priced between $410,176 and $461,448, depending mostly on your down payment. But the honest answer is that this budget behaves very differently depending on where you live, so the number alone only tells part of the story.

The 28/36 math behind the number

Lenders qualify most conventional borrowers using the 28/36 rule: housing costs capped at 28% of gross monthly income, and total debt, including the mortgage, capped at 36%. On $100,000 a year, monthly gross income works out to $8,333. That puts your housing ceiling at $2,333 a month and your total debt ceiling at $3,000 a month. At 6.5% on a 30-year fixed loan, a $2,333 principal and interest payment supports a loan of about $369,159. Add a 10% down payment and the home price you're shopping for lands around $410,176. Push the down payment to 20% and you can go up to roughly $461,448 while keeping the same monthly payment, since a smaller loan needs less of that $2,333 to cover principal and interest.

What that budget actually buys

Here's where a $100,000 income splits into two very different homebuying experiences. In much of the Midwest, the South, and smaller metros, $410,000 to $461,000 buys a genuinely spacious single-family home, often four bedrooms with a yard. In expensive coastal metros like the Bay Area, Seattle, Boston, or much of coastal California, the same budget might only cover a small condo or a starter townhouse, and in some neighborhoods it won't clear the entry price at all. If you're comparing markets, run the same salary through your target city's median home price before assuming the national average applies to you.

The jumbo loan question

Most people earning $100,000 never come close to needing a jumbo loan. The 2026 conforming loan limit for a single-unit home sits well above the roughly $369,159 loan this income supports in the vast majority of US counties. The exception is high-cost areas, where the conforming limit is raised but can still sit close to what a $461,448 home price requires, especially if you're only putting 10% down and financing a larger share of the purchase. If you're house hunting in a designated high-cost county, it's worth checking your county's specific limit on the FHFA website before you get attached to a listing near the top of your range.

Debt changes the picture more than people expect

At $100,000 a year, plenty of buyers still carry student loans or a car payment, and that debt eats directly into the 36% ceiling rather than the 28% housing figure. Take a buyer with a $450 monthly student loan payment and a $350 car payment: that's $800 a month already committed, leaving only $2,200 of the $3,000 total debt ceiling available for housing, taxes, and insurance, which is less than the $2,333 the 28% rule alone would allow. In that scenario the 36% rule becomes the binding constraint, not the 28% one, and the affordable loan amount drops accordingly. Paying off even one of those obligations before applying can meaningfully raise what a lender will approve.

Recap

A $100,000 income comfortably supports a $410,176 to $461,448 home under the 28/36 rule, with a housing payment around $2,333 a month. Where you actually land in that range depends on your down payment, your metro's home prices, and how much of your 36% ceiling is already spoken for by other debt.
