On a $100,000 salary,, you can afford a home of about $293,000 with 10% down at today’s 7.28% mortgage rate. That keeps your full housing payment, about $2,327 a month including property tax, insurance and PMI, at 28% of your gross income. The typical U.S. home costs $429,100. So the answer to how much house can I afford on $100K is “less than the median,” and the reason isn’t really your income.
At $70,000, the monthly payment is what holds most buyers back. At $100,000, something else starts to matter more: the cash you can bring to closing. The payment rules cap you near $293,000, but in some regions a bigger down payment is enough to reach the median home. This guide shows both limits, which one binds for you, and a calculator that finds the price where both work.

How Much House Can I Afford on $100K? The Budget at a Glance
A $100,000 salary is $8,333 a month before tax. Here’s what three common budget rules allow, with $300 a month of other debt and 10% down:
| Comfortable | Standard (28/36) | Stretch | |
|---|---|---|---|
| Home price | $262,000 | $293,000 | $413,000 |
| Monthly housing payment | $2,081 | $2,327 | $3,280 |
| Share of gross income | 25% | 28% | 43% total debt |
| Cash needed (10% down + 3% closing) | $34,060 | $38,090 | $53,690 |
Assumes a 30-year fixed rate of 7.28% (Freddie Mac’s average on October 1, 2026), property tax of 1.1% and home insurance of 0.5% of the price per year, and PMI of 0.6% of the loan per year. These are the same assumptions as our $70K guide, updated for the current rate.
On the standard $293,000 home with $29,300 down, the $2,327 payment breaks down to $1,804 principal and interest, $269 property tax, $122 insurance and $132 PMI. After federal taxes, Social Security and Medicare, a single filer on $100,000 in a state with no income tax takes home about $6,600 a month, so this payment uses about 35% of take-home pay. In a state with income tax, the share is higher.
The Two Limits: Payment and Cash
Every home purchase has to pass two tests. The payment test asks whether your income can carry the monthly cost. Lenders check this with your debt-to-income ratio. The cash test asks whether you can cover the down payment and closing costs on the day you sign.
Most affordability calculators only run the first test and assume you have whatever down payment you type in. That hides the real answer to how much house can I afford on $100K. Here’s how the down payment changes both the price and the cash you need, holding the payment at $2,327:
| Down payment | Home price | Down payment in dollars | Cash to close (down + 3%) |
|---|---|---|---|
| 3.5% (FHA minimum) | $277,000 | $9,695 | about $18,000 |
| 5% | $280,000 | $14,000 | about $22,400 |
| 10% | $293,000 | $29,300 | about $38,100 |
| 20% | $342,000 | $68,400 | about $78,700 |
Look at the jump from 10% to 20% down. It takes about $40,600 more cash, and it raises your price by $49,000, because the bigger down payment both shrinks the loan and removes PMI. Below 10%, extra cash buys much less: going from 3.5% to 10% down takes about $20,000 more and adds only $16,000 to the price. The 3.5% row uses the same PMI estimate for simplicity. A real FHA loan adds an upfront mortgage insurance premium of 1.75% of the loan, usually rolled into the balance.
What It Takes to Buy the Median Home on $100K
The National Association of Realtors put the median existing-home price at $429,100 in August 2026, up 1.6% from a year earlier. This is where “how much house can I afford on $100K” turns into a down payment question. Here’s the down payment a $100K earner would need to keep the payment within the 28% rule for the typical home in each region:
| Region | Median price (Aug. 2026) | Down payment needed | Cash to close (down + 3%) |
|---|---|---|---|
| Midwest | $340,400 | 20% (about $68,000) | about $78,000 |
| South | $366,500 | 26% (about $97,000) | about $108,000 |
| United States | $429,100 | 40% (about $172,000) | about $185,000 |
| Northeast | $556,900 | 58% (about $324,000) | about $341,000 |
| West | $619,100 | 64% (about $399,000) | about $417,000 |
Two things stand out. First, the Midwest median works on one $100K income with a standard 20% down payment. Second, to buy the national median with a normal 10% down payment, you’d need an income of about $146,000. With $100K, you can either bring more cash, buy below the median, or buy with a second income. Two $100K incomes with $300 of combined debt can afford about $587,000 at 10% down.
For context, NAR’s 2025 buyer survey found first-time buyers put down a median of 10%, the highest since 1989, and the median first-time buyer is now 40 years old. The cash test is a big part of why people are buying later.
$100K House Affordability Calculator
This calculator answers how much house can I afford on $100K by running both tests at once. Enter your income, your monthly debts and the cash you have for the purchase. It finds the highest price where your payment fits the budget rule and your cash covers closing costs plus at least 3.5% down, then tells you which limit is holding you back.
Taxes, insurance, HOA and closing costs
The calculator finds the highest price where both limits hold: your monthly payment stays within the budget rule you picked, and your cash covers closing costs plus at least 3.5% down (the FHA minimum). Whatever cash is left after closing costs goes to the down payment. PMI is added when the down payment is under 20%. FHA loans use their own mortgage insurance, which can cost more. Estimates only, not a loan offer. Nothing you enter leaves your browser.
What Changes the Answer
Your Other Debts
When you ask how much house can I afford on $100K, your other debts matter less than you might expect, up to a point. At this income, the 36% total-debt limit leaves room for about $667 a month of other payments before it starts to cut into the 28% housing budget. Beyond that, every extra $100 a month costs you about $12,500 of home price.
| Other monthly debts | Affordable home price |
|---|---|
| $0 to $600 | $293,000 |
| $900 | $264,000 |
| $1,200 | $226,000 |
The Mortgage Rate
Rates have climbed back above 7% this fall. Here's how the same $2,327 payment translates into price at different rates:
| Mortgage rate | Affordable home price |
|---|---|
| 6.0% | $325,000 |
| 6.5% | $312,000 |
| 7.0% | $300,000 |
| 7.28% | $293,000 |
| 7.5% | $288,000 |
| 8.0% | $278,000 |
Each half-point is worth about $10,000 to $13,000 of price. Your credit score is the part of the rate you control; our guide to the credit score you need to buy a house shows what each score band costs.
Property Tax and Insurance
With a property tax rate of 0.5%, the same $100K buyer can afford about $313,000. At 2.0%, the budget drops to about $268,000. Home insurance works the same way, and in states with high storm or wildfire risk it can cost far more than the 0.5% assumed here. Get a real insurance quote and the county's tax rate before you set a budget, and enter both in the calculator's settings.
How Much Cash to Plan for Closing
Closing costs are the part people forget when they search "how much house can I afford on $100K." LodeStar Software Solutions found purchase closing costs averaged $4,528 in 2025, or 1.04% of the price. That figure covers title, settlement, recording fees and transfer taxes only, and it ranged from 0.39% of the price in South Dakota to 3.07% in Delaware. Lender fees, prepaid interest and the first deposits into your escrow account for taxes and insurance come on top, which is why lenders usually tell buyers to plan for 2% to 5% of the price. This guide uses 3%.
After closing, keep three to six months of expenses in the bank. A new home tends to need repairs in the first year, and an empty savings account turns the first broken water heater into credit card debt. Our emergency fund calculator helps you set that number.
A Stress Test in Australia, a Loan Cap in Korea
In Australia, banks test you at a rate you aren't paying. The banking regulator, APRA, expects lenders to check that you could still make the payments if your rate were 3 percentage points higher. A buyer offered 6% has to qualify at 9%. Borrow more than 80% of the price and you pay lenders mortgage insurance, usually as a one-off upfront cost. The cash test is also tougher there because of stamp duty, a state tax on the purchase that can run to tens of thousands of dollars. New South Wales waives it for first-home buyers on homes up to $800,000.
Korea caps the loan directly. Instead of a housing-cost ratio, Korean banks use DSR, a limit on all loan payments, which is capped at 40% of income for bank loans, and a "stress" rate is added when they calculate it. Since the June 2025 measures, mortgages in the Seoul metropolitan area have also been capped at ₩600 million regardless of income or price. In both countries, the system decides the maximum for you. In the U.S., lenders will often approve far more than the 28% rule, up to about 43% or more of income in total debt, so the limit has to come from your own budget.
How Much House Can I Afford on $100K? 5 Ways to Get More
- Find out which limit binds. If cash is your limit, saving more is the fastest lever. If income is, paying off a car loan or shopping for a lower rate helps more.
- Aim for 20% down if you're close. The jump from 10% to 20% adds about $49,000 to your price because PMI disappears.
- Look at first-time buyer programs. Many states offer down payment help, and some have income limits above $100,000, especially in high-cost areas.
- Get three lender quotes. A quarter-point lower rate adds about $6,000 to your budget at this income.
- Compare with renting. If the numbers only work at the stretch level, our rent vs buy calculator shows whether waiting and investing the difference comes out ahead.
