The tool makes the assumption that the annual property tax payment is 1.15% of the home’s market value.
A constant interest rate of 4.25% and loan duration of 30 years are used to calculate the annual mortgage payment using an ordinary annuity formula. The monthly mortgage payment is derived by dividing the annual payment by 12.
Lenders often resell the mortgage to government-sponsored enterprises Fannie Mae and Freddie Mac. These loans need to conform to the Fannie Mae and Freddie Mac guidelines. One important requirement is the need to pay mortgage insurance if the down payment is less than 20% of the home value. While there are different kinds of nonconforming loans, like FHA, VA, or jumbo loans, we are treating all the loans as conforming loans with only private option for mortgage insurance (PMI). The maximum loan value constraint is also ignored for simplicity. The annual amount of PMI is assumed to be 0.5% of the home value. If the “Use PMI” option is not selected, the PMI amount is excluded from the calculations and the down payment is not allowed to fall below 20% of the home value. If the “Use PMI” option is selected, the PMI amount is considered and the tool may produce a solution that includes a down payment as low as 5%. Speak with your lender for more detailed information about PMI.
Buying costs are assumed to be 2% of the home value. The chosen current savings amount is assumed to cover both down payment and buying costs.
Home insurance is assumed to be 0.35% of the home value per year. Maintenance and improvement costs are assumed to amount to 0.5% of the home value per year.
Monthly costs include the mortgage payment, property taxes, home insurance costs, and PMI (if applicable).
The calculator estimates and outputs the maximum home value that satisfies these two conditions:
