Pay PMI or Put 20% Down? (2026 Decision Guide)
Many buyers ask whether they should buy sooner with PMI or wait until they can put 20% down. The right answer depends on your monthly cushion, local price trends, and how quickly you can build equity.
Quick answer
If buying now keeps your payment safely affordable and your emergency reserve intact, paying PMI can be reasonable. If PMI strains monthly cash flow or leaves you under-reserved, waiting to increase down payment can be safer.
What to compare before deciding
- Monthly payment difference: with and without PMI
- Cash reserve after closing: emergency fund matters more than a perfect down payment
- Expected holding period: short stay vs long-term ownership changes the math
- Market conditions: rent trend, home price trend, and rate trend
Example framework
On a $400,000 home, 10% down may add monthly PMI but lets you buy earlier. Waiting for 20% removes PMI but delays purchase and may change home price/rate assumptions. Your break-even depends on total monthly cost, expected appreciation, and your savings pace.
When buying now with PMI is often reasonable
- You keep a 3–6 month emergency buffer after closing
- Your all-in payment still fits a conservative budget
- You can make occasional extra principal payments to remove PMI sooner
When waiting for 20% is usually better
- Current payment would be tight every month
- You would deplete savings to close
- You need more time to improve credit and reduce rate cost

FAQ
Is paying PMI always a bad idea?
No. PMI can be a practical tradeoff if it lets you buy sooner while keeping a safe monthly budget and emergency reserve.
Can I remove PMI later if I buy with less than 20% down?
Yes, on conventional loans you can often request cancellation near 80% LTV and automatic removal generally occurs near 78% LTV if conditions are met.
