When does conventional require PMI?
Whenever the LTV at closing exceeds 80% (down payment less than 20% on a purchase, or remaining balance above 80% of value on a refinance). PMI is required regardless of credit score — strong credit just makes it cheaper, not optional.
What this actually means.
Conventional PMI applies above 80% LTV on most loans. The threshold is purchase-time: 20% down avoids PMI from day one. On a refinance, 80% LTV (based on appraised value) avoids PMI. On a non-purchase situation where the original loan was below 80% LTV, PMI was never charged. Subject to Fannie/Freddie guidelines.
Where this can move.
Credit score, LTV, coverage percentage, occupancy, and PMI provider can change cost. PMI removal is governed by HPA and servicer policy.
