Translate household income and debt constraints into a realistic home price range.
Overview
Affordability is more reliable when based on debt ratios and full housing costs.
This calculator estimates maximum payment and implied purchase price range.
It considers income, existing debts, and financing assumptions.
Using conservative inputs can prevent post-purchase cash-flow stress.
Steps
Use stable household pre-tax income.
Include recurring liabilities and minimum payments.
Choose a conservative total debt-to-income threshold.
Add rates, term, taxes, and insurance estimates.
Review payment ceiling and implied home price band.
Math
Max Housing Payment = Income × DTI Target - Other Debts
Affordability starts with debt-capacity limit after subtracting non-housing obligations.
Worked cases
Max housing = 9,000×0.40 - 1,000
Housing payment target is about $2,600/month.
Recompute max housing payment.
Affordability range increases after debt reduction.
Convert payment ceiling to lower loan amount.
Affordability price range drops when rates rise.
