It estimates the monthly payment on an FHA loan, including the upfront and annual mortgage insurance premiums (MIP) that FHA loans require.
How It Works, Step by Step
The calculator adds the upfront MIP to the base loan, runs the total through the amortizing-payment formula for principal and interest, then layers in the monthly MIP plus estimated taxes and insurance.
FHA loans are popular with Florida first-time buyers because of the low 3.5% down payment and flexible credit requirements. FHA also sets county loan limits that vary across Florida — higher in expensive coastal counties — so the maximum FHA loan you can use depends on where you buy.
