Understanding Your Mortgage Payment

What's Included in Your Payment?

PITI = Principal, Interest, Taxes, Insurance. Many lenders require PMI if you put down less than 20%. Don't forget HOA fees if applicable.

Down Payment Impact

20% down eliminates PMI (saving $100-300/month). However, a smaller down payment helps you buy sooner while preserving savings.

15 vs 30 Year Terms

30-year: Lower monthly payments, more flexibility, more total interest. 15-year: Higher payments, faster equity building, significant interest savings.

Tips for Home Buyers

  • Aim for payment under 28% of gross income
  • Get pre-approved before shopping
  • Compare multiple lenders
  • Consider total cost, not just monthly payment

While 20% avoids PMI, many buyers put 3-10% down. Balance your down payment against emergency fund and other goals. A larger down payment means lower monthly payments and less total interest.

What is PMI and how can I avoid it?

PMI is required with less than 20% down, typically 0.5-1% annually. Avoid with 20% down, lender-paid PMI, or VA/USDA loans. PMI drops automatically at 20% equity.
