Formula and Logic
The calculator uses the standard 28/36 rule for mortgage affordability. It estimates your maximum monthly payment as 28% of your gross monthly income minus existing debts. The loan amount is calculated using the present value of an annuity formula: PV = PMT * [(1 - (1 + r)^-n) / r], where PMT is the monthly payment, r is the monthly interest rate, and n is the number of payments. The maximum home price is the loan amount plus your down payment.
Practical Notes
- Local market variation: Home prices and property taxes vary significantly by region; adjust your expectations accordingly.
- Closing cost components: Budget 2-5% of the home price for closing costs, including appraisal, title insurance, and legal fees.
- Rental yield benchmarks: For investment properties, consider rental income potential and vacancy rates in your area.
- Financing options: Explore FHA, VA, or conventional loans based on your eligibility and down payment amount.
Why This Tool Is Useful
