What is Mortgage Insurance?
Mortgage insurance protects the lender (not the borrower) against losses if the borrower defaults on the loan. It is required when the borrower makes a down payment of less than 20% on a conventional loan or on all FHA loans regardless of down payment. Mortgage insurance allows lenders to make loans to borrowers with smaller down payments by shifting some of the default risk to an insurance company.
There are two primary types: Private Mortgage Insurance (PMI) for conventional loans and Mortgage Insurance Premium (MIP) for FHA loans. VA loans do not require mortgage insurance but charge a one-time funding fee. USDA loans charge a guarantee fee that functions similarly to mortgage insurance.
PMI vs. MIP
PMI (Private Mortgage Insurance): Applies to conventional loans with less than 20% down. Annual cost ranges from 0.3% to 1.5% of the loan amount depending on credit score, down payment, and loan-to-value ratio. PMI can be cancelled once the LTV reaches 80% through payments or appreciation. PMI automatically terminates when LTV reaches 78% based on the original amortization schedule.
MIP (Mortgage Insurance Premium): Required on all FHA loans. Consists of an upfront premium (1.75% of the loan amount, usually financed into the loan) plus an annual premium (0.45-1.05% depending on LTV, term, and loan amount). For most FHA borrowers, MIP is required for the life of the loan and cannot be cancelled without refinancing into a conventional loan.
Cost impact
On a $250,000 loan with 5% down, PMI might cost $100-$250 per month. Over the years before reaching 80% LTV, this adds $5,000-$15,000 in total cost. This is a significant expense that reduces cash flow for rental property investors using conventional financing with low down payments.
Mortgage insurance and investors
Most investor loans require 15-25% down payment, which often eliminates the PMI requirement. However, house-hacking strategies (buying a 2-4 unit property as an owner-occupant with FHA financing at 3.5% down) do involve MIP. Understanding the true cost of MIP helps investors calculate whether the leverage benefit of low down payment outweighs the insurance cost over the holding period.
