The calculator is prefilled with a $40,000 income and an estimated 6.60% rate — add your down payment and debts for your exact number. Worked examples for this salary below.
Compare rates and get pre-approved. Shopping multiple lenders can save tens of thousands over the life of a loan.

Buying a house on a $40,000 salary is possible, but the strategy matters more than at any other income. The standard 28% rule gives you about $933/month for housing — mortgage, property tax, and insurance together — which supports a home around $98,000 with 10% down at today's rates.
Two things move the needle most at this income: existing debt (every $100/month of payments below the caps costs roughly $15,700 of house) and down-payment help. USDA loans offer zero-down financing in eligible rural and suburban-edge areas, and nearly every state's housing finance agency offers assistance grants or forgivable second loans to buyers in this income range — most people who qualify never apply.
Lenders size mortgages with the 28/36 rule: housing costs under 28% of gross monthly income, all debt payments combined under 36%. On $40,000 a year ($3,333/month gross), that means:
| Max housing payment (28% front-end) | $933/mo |
| Max total debt payments (36% back-end) | $1,200/mo |
| Other-debt headroom before it cuts your house budget | $267/mo |
Benchmark buyer: $400/month of existing debts, 30-year fixed at an estimated 6.60% (mid-2026 national ballpark), property tax and insurance estimated at 1.1% and 0.5% of the price per year:
| ≈5% down ($5,000) | $94,000 |
| ≈10% down ($10,000) | $98,000 |
| ≈20% down ($21,000) | $107,000 |
The monthly cost is about $800 in every row — the 28/36 cap is what limits you. The down payment decides how much house that budget buys, and at 20% it also drops PMI from the payment.
Debts. On a $40k salary you can carry about $267/month of non-housing debt before it starts cutting into the housing budget. The benchmark's $400/month is already past that line — every extra $100/month of payments removes roughly $15,700 of house, and paying debt off adds it back.
Rate. With the same 10%-down benchmark, a 5.60% rate supports about $101,000 and a 7.60% rate about $94,000. Lender quotes on the same borrower routinely differ by 0.25–0.5%, so shopping at least three lenders is the cheapest rate cut available.
Location. The benchmarks assume the ~1.1% national-average property tax. In a 2%+ tax state the same monthly budget buys meaningfully less house; in a low-tax state, more.
