Free interactive mortgage tool

Home affordability planner

Explore a possible purchase price from the monthly housing payment you would prefer, without assuming an underwriting debt ratio.

How the tool works

Use the formula. Then challenge the assumptions.

This planner works backward from a preferred complete housing payment. It subtracts estimated taxes, insurance, mortgage insurance, association costs, and community assessments before estimating the principal-and-interest amount and possible loan size.

Two homes with the same price can produce different affordability results when one has higher insurance, taxes, HOA dues, or CDD assessments. The property changes the payment even when the loan amount is identical.

Inputs to verify

The result is only as useful as the numbers.

  • A payment the household is comfortable carrying
  • Down payment and funds remaining after closing
  • Interest rate and term
  • Property taxes and insurance
  • Mortgage insurance
  • HOA and community assessments

Questions to ask

Before relying on the result

  • How much cash should remain after closing?
  • Which expenses are not included in the calculator?
  • Would the payment still feel comfortable after normal household expenses?
