This is a planning range, not a lender pre-approval. Taxes, insurance, HOA dues, and underwriting rules can reduce affordability.
How to use this house affordability calculator
Use this house affordability calculator to translate income, debt, cash available, and financing assumptions into a planning range. It is intentionally separate from lender approval and should be tested with a conservative housing ratio.
- 1
Enter stable household income
Use gross annual income that is reasonably expected to continue and include recurring monthly debt obligations.
- 2
Set cash and financing assumptions
Enter the down payment available after preserving reserves, then use a realistic mortgage rate and term.
- 3
Choose a housing ratio
Test a lower maximum housing-to-income ratio to preserve room for taxes, insurance, maintenance, savings, and lifestyle costs.
Worked planning example
Example: approval range versus comfortable range
Set up
Model a household’s gross income, recurring debt, down payment, and current mortgage-rate estimate.
Compare
Run one case at the maximum ratio being considered and another at a lower ratio, then compare the implied home prices.
Takeaway
The amount a household might qualify to borrow can be higher than the amount that leaves comfortable monthly cash flow.
Affordability is broader than a lending ratio
The result is a planning estimate, not underwriting, and cannot see every cost attached to a property or household.
- Preserve cash for closing costs, repairs, moving, and emergencies.
- Include HOA dues, insurance, taxes, and maintenance in the final property review.
- Consider income volatility and future savings goals before using the maximum result.
Calculation methodology and assumptions
For this house affordability estimate, Silvia uses gross annual household income, monthly debt payments, available down payment, mortgage interest rate, mortgage term, maximum housing-to-income ratio. Estimate an affordable home price using income, existing debt, down payment, rates, and housing costs. Results are estimates, not quotes, tax advice, or investment recommendations.
Frequently asked questions
Is this the same as mortgage preapproval?
No. Preapproval depends on lender underwriting, credit, income documentation, assets, property details, and loan-program rules.
Should I use gross or take-home income?
Use gross household income because the calculator’s housing ratio is defined against gross income. Your personal budget should still be tested against take-home pay.
Does the result include closing costs?
No. The entered down payment is applied to the purchase price. Keep a separate reserve for closing costs, moving, repairs, and initial ownership expenses.
