About This Tool
The Home Affordability Calculator determines your maximum comfortable residential purchase price and mortgage loan size using traditional underwriting debt-to-income (DTI) thresholds. The estimator models two borrowing tiers: a conservative guideline capping front-end housing expense at 28% of gross monthly income and back-end total debt at 36%, alongside an aggressive borrowing scenario capped at 43% total DTI. Factoring in an estimated 22% allocation for property taxes, homeowner insurance, and PMI, the calculator models 30-year fixed loan principal and adds available down payment funds to display target home price tiers. All income figures and debt numbers evaluate locally in browser memory with zero server logging.

Frequently Asked Questions
What is the 28/36 mortgage qualifying rule?
Lenders traditionally prefer monthly housing costs to stay below 28% of gross income and total debt payments below 36%.
How does credit tier affect estimated affordability?
Higher credit tiers qualify for lower mortgage rates, reducing monthly interest expense and expanding maximum borrowing power.
