The difference between 3% and 20% down on a $500K home is $774/month. Over 5 years, that's $46,430 extra — plus PMI. If you can wait and save to 20%, it's almost always worth it.
What Is PMI and How Do You Avoid It?
Private Mortgage Insurance (PMI) protects the lender — not you — if you default. It typically costs 0.5-1% of the loan amount annually. On a $500K home with 3% down, that's approximately $2,500/year in PMI alone.
You can request PMI removal once you reach 20% equity in the home (through payments + appreciation). But the fastest way to avoid it is to put 20% down from the start.
FHA vs Conventional: Which Is Better?
- FHA (3.5% down): Best for credit scores 580-679. Lower down payment but higher long-term cost due to MIP (mortgage insurance premium that lasts the life of the loan)
- Conventional (5-20% down): Best for credit scores 680+. PMI can be removed; MIP cannot on FHA
- Verdict: If your credit score is 680+, conventional almost always wins long-term
