What does PMI cost?

Costs vary from insurer to insurer, as well as from plan to plan. For example, a highly leveraged adjustable rate mortgage would require the borrower to pay a higher premium to obtain coverage. Buyers with 5% down payment can expect to pay a premium of approximately 0.78% times the annual loan amount ($92.67 monthly for a $150,000 purchase price). But the PMI premium would drop to around 0.52% times the annual loan amount ($58.50 monthly) if a 10% down payment was made on the loan.
