Monthly budget at 28%
A $100k salary is $8,333 a month before tax. 28% of that, $2,333, is the housing budget; with no other debts the 36% limit ($3,000) is higher, so 28% sets the price.
| Principal and interest ($295,989 loan) | $1,871 |
|---|---|
| Property tax (1% of price a year) | $308 |
| Home insurance (0.5% of price a year) | $154 |

By down payment
A smaller down payment means a larger loan for each dollar of price, so the same budget buys less: $317,484 with 3.5% down against $369,986 with 20% down.
| Down payment | Max price | Cash down | Loan |
|---|---|---|---|
| 3.5% | $317,484 | $11,112 | $306,372 |
| 5% | $321,633 | $16,082 | $305,551 |
| 10% | $336,282 | $33,628 | $302,654 |
| 20% | $369,986 | $73,997 | $295,989 |
Under 20% down, conventional loans usually add private mortgage insurance, and FHA loans (3.5% minimum down for many borrowers) add mortgage insurance premiums. Neither is included, so the rows under 20% overstate the price.
With other monthly debts
Car, student loan and card minimum payments count against the 36% limit. At this salary they start to lower the price above $667 a month (8% of gross monthly income).
| Other debts | Housing budget | Max price | Limit that binds |
|---|---|---|---|

| $1,000 a month | $2,000 | $317,131 | 36% total debt |
By interest rate
| Rate | Max price | Loan |

Median values and tax rates: Census ACS 2020–2024 (owner estimates in 2024 dollars, not sale prices). Insurance: NAIC HO-3 average premium, 2023. The tax rate is the median tax bill divided by the median value. Local prices, tax bills and premiums vary widely within a state.
Assumptions
- Defaults: 20% down, a 30-year fixed loan at an illustrative 6.5% (not a current rate), property tax of 1% and home insurance of 0.5% of the price per year, no HOA dues and no other monthly debts.
- The housing payment (principal, interest, tax and insurance) is capped at 28% of gross monthly income, and housing plus other debts at 36%; the lower cap sets the budget. 28% is a common rule of thumb; 36% is the Fannie Mae maximum for manually underwritten loans, which it allows to be exceeded in some cases. Lenders set their own limits, so this is not an approval estimate.
- Excluded: private mortgage insurance, FHA mortgage insurance, HOA dues, closing costs, cash reserves and credit score effects. Property tax and insurance vary widely by state and county, so replace the placeholders with local figures.
- Salary means gross (before-tax) yearly income. Figures are rounded to whole dollars; the calculator shows cents.

When do other debts lower the price?
When they exceed $667 a month, 8% of gross monthly income. Above that, housing plus debts would pass 36% before housing alone reaches 28%, so the 36% limit sets a lower budget.
