A 20% down payment eliminates PMI and significantly lowers monthly interest amortizations.
Current Mortgage Market Outlook
Navigating the housing market requires a clear understanding of key mortgage mechanics: credit score tiers, debt-to-income (DTI) ratios, discount points, and loan structures.
Key Factors That Control Your Mortgage Rate
- Credit Score (FICO): Buyers with FICO scores above 760 routinely receive interest rate quotes up to 1.25% lower than buyers with 640 credit scores.
- Debt-to-Income (DTI) Ratio: Lenders prefer a total DTI under 36%, with no more than 28% allocated strictly to housing debt (the 28/36 rule).
- Loan-to-Value (LTV): Putting down 20% eliminates Private Mortgage Insurance (PMI), saving $150 to $400 per month on average.
Frequently Asked Questions
What is Private Mortgage Insurance (PMI) and how can I avoid it?
PMI is an added monthly fee charged by lenders to insure conventional loans when your down payment is less than 20%. It automatically terminates once your equity reaches 22% of home value.
