Questions about house affordability calculator
How is the price worked out?
Your monthly housing budget is the smaller of a share of income (28% by default) and a larger share of income (36%) less your other debts. The tool finds the price whose mortgage, tax, insurance and fees fit within it.
Will a lender approve this amount?
Not necessarily. Lenders also check credit history, savings, job history and their own limits.
Is mortgage insurance included?
No. If your down payment is small, a lender may add mortgage insurance, which lowers the price you can afford.
How the price is found
Lenders usually cap housing costs at a share of income, and total debt payments at a larger share. With 90,000 of income, 28% for housing allows 2,100.00 a month and 36% for all debts allows 2,300.00 after 400 of other payments. The smaller one, 2,100.00, is the budget.
The tool then finds the price whose mortgage, property tax at 1.1% of the price and 1,500 a year of insurance all fit in that budget. With 50,000 down at 6.5% over 30 years that is 316,557.16, with a mortgage of 266,557.16. The table shows how income changes the answer.
| Yearly income | Home price you can afford | Mortgage |
|---|---|---|
| 60,000 | 219,837 | 169,837 |
| 80,000 | 284,317 | 234,317 |
| 100,000 | 348,797 | 298,797 |
| 120,000 | 413,278 | 363,278 |
| 150,000 | 509,998 | 459,998 |
Rate, down payment and what is left out
The mortgage rate matters a great deal. With the same inputs the price is 342,539.25 at 5.5%, 316,557.16 at 6.5% and 293,926.23 at 7.5%. An extra 10,000 of down payment adds 8,733.42 to the price.
Mortgage insurance, closing costs, moving costs, repairs and utilities are not included, and lenders also check credit history, savings and job history. The 28% and 36% limits are common guidelines. You can change them under More options to match your lender.
