How Mortgage Qualification Works

1

DTI Evaluation

Lenders restrict your maximum monthly mortgage payment so total debts stay within 36% to 45% of income.

2

Full PITI Sum

Approval amounts factor in principal, interest, local property taxes, homeowners insurance, and PMI.

3

Down Payment Power

Reaching a 20% down payment eliminates PMI entirely, reducing monthly fees and boosting pre-approval.
