How Much House Can You Afford on $70,000 a Year?
On a $70,000 salary, take-home pay after federal taxes runs roughly $4,600–$4,850 a month depending on your state. Using a comfortable 36% debt-to-income ceiling and today's mortgage rates, that puts most households in the $140,000–$150,000 range for a home purchase with a modest down payment — well below the roughly $230,000+ a lender's pre-approval letter might show, because pre-approval math and comfortable math aren't the same calculation.
At an August 2026 average 30-year fixed rate of 6.66%, a $70,000 earner with typical existing debt (say, a $400/month car payment) and a 10% down payment can comfortably afford a home priced around $143,000–$150,000, with a monthly payment near $1,290 covering principal, interest, taxes, and insurance (PITI). That number moves a lot depending on three things: how much you put down, what else you owe every month, and where mortgage rates sit when you buy.
How the math actually works
Lenders typically size a mortgage using your gross income (pay before taxes) and a debt-to-income ratio as high as 43% for a "qualified mortgage." That's how pre-approval letters often land at a much higher number than what actually fits your budget once taxes, take-home pay, and real monthly bills enter the picture.
HowAffordable calculates against your take-home pay instead, and caps total monthly debt — housing plus everything else — at 36% for a comfortable ("B" or better) result, or 28% for an "A." That's a meaningfully more conservative standard, and it's the reason our numbers usually come in lower than a lender's maximum. Lower isn't a worse answer; it's the answer that's less likely to leave you house-poor.
The full calculation stacks four pieces on top of your loan's principal and interest:
- Principal & interest (P&I) — the standard amortizing-loan formula, based on your loan amount, interest rate, and term.
- Property tax — estimated at 2% of the home's value annually (this varies significantly by state and county; some run under 0.5%, others over 2%).
- Homeowners insurance — a typical estimate of about 0.5% of home value annually.
- PMI — roughly 1.5% of your loan amount annually, but only if your down payment is under 20%. This one disappears entirely once you cross that line — see our PMI guide for exactly how.
Worked example: $70,000/year, $400/month existing debt
| 10% down | 20% down | |
|---|---|---|
| Take-home pay used | $4,700/mo | $4,700/mo |
| Existing monthly debt | $400 | $400 |
| Target DTI ceiling | 36% | 36% |
| Affordable home price | ≈ $143,700 | ≈ $178,800 |
| Loan amount | $129,300 | $143,100 |
| Down payment | $14,400 | $35,800 |
| Principal & interest | $831 | $919 |
| Property tax (2%/yr) | $239 | $298 |
| Homeowners insurance | $60 | $75 |
| PMI | $162 | $0 |
| Total monthly PITI | $1,292 | $1,292 |
| Leftover after housing + debt | $3,008 | $3,008 |
Rate used: 6.66% (Freddie Mac's 30-year fixed average, week of Aug. 27, 2026). One illustrative household — run your own numbers in the home affordability calculator.
Notice that both columns land on the exact same $1,292 monthly payment and the exact same leftover cash — the 20% down payment doesn't make your budget more comfortable, it makes your budget stretch to a bigger home at the same comfort level, because dropping PMI frees up room that goes straight into home price instead.
What changes this number most
Frequently asked questions
Does this include property tax and homeowners insurance, or just the mortgage payment?
All four pieces — principal, interest, property tax, and insurance, plus PMI where it applies — are included in the price ranges above. A quote that only shows principal and interest will look smaller, but it isn't the number you'll actually pay every month.
Why is this lower than the number my lender's pre-approval showed me?
Lenders commonly qualify borrowers up to 43% of gross (pre-tax) income in total debt. This guide targets 36% of take-home (after-tax) pay instead — a more conservative number that leaves room in your monthly budget instead of maximizing what a bank will let you borrow. Both numbers are "correct"; they're answering different questions.
Is $70,000 a good salary for buying a first home?
It's workable in most of the country, particularly outside high-cost coastal metros. The affordable range in this guide reflects national averages — your real number shifts with your specific state's property tax rate, your credit-driven interest rate, and any debt you're carrying.
How often should I recheck this number?
Whenever your income, debt, or the prevailing mortgage rate changes meaningfully — and at minimum, once a year, since property tax assessments, PMI thresholds, and average rates all shift annually.
