Understanding Key Mortgage Factors

DTI measures how much of your income goes toward debt.

  • Below 36% → Ideal
  • Up to 43% → Acceptable
  • Above 43% → Risky

🔹 Interest Rate

Affects your monthly payment and total loan cost. Lower rates mean lower payments.

🔹 Loan Term

  • 15 years → Higher payments, less interest
  • 30 years → Lower payments, more interest

🔹 Credit Score

Higher scores improve approval chances and loan terms.
