How Much House a $100K Salary Can Actually Buy

$100,000 a year feels like good money. And it is. But I can’t tell you how many times I sat across from someone earning exactly that, feeling confident they could afford a $600,000 home, and had to walk them through why that math was going to hurt them.

The number that gets thrown around most often is “2.5 to 3x your income,” which would put you somewhere between $250,000 and $300,000. But honestly, that rule of thumb comes from an era of 3% mortgage rates and lower property taxes, and it doesn’t account for how different two people’s financial lives can be. Someone earning $100,000 with no debt, a 20% down payment saved, and low property taxes in the Midwest is looking at a completely different picture than someone earning the same salary with student loans, a car payment, and shopping in a high-cost-of-living metro.

So let’s actually work through this. Not with slogans, but with the real numbers.

The Calculation That Actually Matters: Your DTI

Here’s what lenders care about, and what you should care about too: your debt-to-income ratio, or DTI. This is your total monthly debt payments divided by your gross monthly income (before taxes). Most conventional loans want your total DTI at or below 43%, though some lenders will stretch to 45% or even 50% in certain programs.

On a $100,000 salary, your gross monthly income is about $8,333.

The front-end DTI (housing costs only, including principal, interest, taxes, insurance, and HOA if applicable) should typically stay at or below 28%. That puts your housing budget at around $2,333 per month.

The back-end DTI (all debt combined) caps at 43% for most loans, which is $3,583 per month. The difference between those two numbers is how much room you have for other debt: car loans, student loans, credit card minimums.

This is where the “afford” question gets personal. If you’ve got $600 a month going to a car payment and $300 in student loans, you’ve already used $900 of your available back-end DTI cushion. Your housing payment may need to come down to $2,200 or less to stay within guidelines.

I’ve seen people get pre-approved for more than they should borrow because they were technically within the 43% back-end threshold. Being approved isn’t the same as being comfortable. The mortgage will be paid, but groceries and emergencies will feel tight.

What $100K Actually Gets You (By the Numbers, as of July 2026)

Let’s run three real scenarios. These use current rates (as of July 2026, 30-year fixed conventional rates are generally hovering in the mid-to-upper 6% range, though they shift daily, and I’m not going to quote you a specific rate as if it’s guaranteed). I’m using 6.75% as a working assumption, but use a mortgage calculator to plug in whatever rate you’re quoted. The Consumer Financial Protection Bureau’s loan estimate explainer is a great place to understand what’s in that payment.

That last row is technically approvable in some programs. But $3,704 a month on an $8,333 gross income means you’re taking home maybe $6,200 after taxes, contributing nothing to retirement, and hoping nothing breaks in the first year. I’ve watched that scenario become very stressful, very fast.

The taxes and insurance estimates in that table will vary significantly by location. Property taxes in Texas or New Jersey can be 2-2.5% of the home’s value annually. In states like Hawaii or Alabama, they’re much lower. Don’t gloss over that column.

The Hidden Costs Nobody Budgets For

Here’s what I tell people who are fixating on the monthly payment: that number is the floor, not the ceiling.

Maintenance and repairs run roughly 1% of your home’s value per year on average, though older homes run higher. On a $350,000 house, that’s $3,500 a year, or about $292 a month you should mentally reserve. Some years you spend nothing. Then the HVAC gives out (typically $5,000 to $10,000 to replace) or the roof needs work ($8,000 to $15,000 for a full replacement on a mid-size home), and suddenly that reserve looks necessary.

Closing costs are another thing buyers tend to underestimate. On a $350,000 purchase, you’re typically looking at 2-5% of the loan amount in closing costs, so $6,300 to $15,750. That’s separate from your down payment. If you’ve saved $35,000 expecting it to cover both, you may be short.

And if you’re putting less than 20% down, you’ll pay private mortgage insurance (PMI), which typically runs 0.5-1.5% of the loan amount annually. On a $315,000 loan, that’s roughly $130 to $394 a month tacked onto your payment until you hit 20% equity. It disappears eventually, but it’s real money in the meantime.

Worked example: A couple in Columbus, Ohio earning a combined $100,000 bought a $320,000 home with 8% down. Loan amount: $294,400. Their estimated monthly payment including PMI, taxes, and insurance came to about $2,580. On their take-home of roughly $6,400 per month after taxes, that’s 40% of actual take-home going to housing. They made it work, but had to pause their 401(k) contributions for two years. They’d do it differently in hindsight.

How Location Changes Everything

The “how much house” question is really a “where are you buying” question in disguise. $350,000 in Memphis, Tennessee buys a lot of house. In San Jose, California, it’s a down payment conversation. And your property tax rate, which varies enormously by state and county, changes your monthly payment in ways the purchase price alone won’t show you.

Scenario: Same $100,000 salary, $350,000 home purchase. Same 10% down. Different states.

• In Austin, Texas: property taxes can run 2.1-2.4% of value. On $350,000, that’s $7,350 to $8,400 a year, or $613 to $700 a month. Your housing payment could easily exceed $3,000.
• In Phoenix, Arizona: property taxes are around 0.6-0.8%. On $350,000, that’s roughly $175 to $233 a month. Your total payment might come in under $2,500.

Same house price, $500+ difference in monthly cost. Location isn’t a footnote. It’s a main variable.

What I’d Actually Do, If I Were You

I thought for a long time that lenders were giving borrowers solid guidance when they issued pre-approval letters. Then I underwrote enough files to see the full picture, and I changed my mind. A pre-approval tells you the maximum you can borrow within lending guidelines. It doesn’t tell you the maximum you can borrow and still sleep well at night.

Here’s the approach I’d take. Start with your real after-tax take-home pay, not your gross. Calculate what 30-35% of that is. That’s your housing budget ceiling. Then work backward to the home price.

On a $100,000 salary, after-tax take-home varies by state and personal deductions, but let’s estimate $6,000 to $6,800 a month. Thirty percent of $6,400 is $1,920. That’s a comfortable housing payment. Thirty-five percent is $2,240. That’s manageable but tighter. Anything above that and you’re in “technically survivable but stressful” territory.

If HUD-approved housing counselors are available in your area (and they often offer free consultations), use them before you start shopping. They’ll help you build an actual budget around the full picture, not just the mortgage payment.

One more worked example: A teacher in suburban Denver earning $98,000, no car payment, $200/month in student loans, and $60,000 saved. She targeted a $380,000 home, put 15% down ($57,000), kept $3,000 in savings as a small emergency buffer. Monthly payment including PMI, taxes, insurance: about $2,800. Front-end DTI: 33.6%. Back-end DTI (with student loan): 35.9%. Approved, and comfortably within her budget because her back-end was clean. Three years later, she hit 20% equity, dropped PMI, and her payment came down by $140/month.

A Word About the Current Market

Inventory in many metros is still tight as of this year, which means buyers are competing, and it’s tempting to stretch your budget to stay competitive. This is when buyers get in trouble. Bidding $30,000 over list price to win a home sounds like strategy, but that $30,000 gets folded into your mortgage and financed at whatever rate you’re paying for the next 30 years. At 6.75%, that $30,000 extra costs you roughly $700 in additional interest over the life of the loan per thousand dollars borrowed. Do the math on what “winning” that bidding war actually costs you monthly and cumulatively.

I’m not saying don’t compete. I’m saying know the price of winning.
