There are a few things you should know about short sale flips and FNMA. First and forecmost, you need to read the FNMA Flipping Requirements as an investor of real estate.
Second, you need to find an FNMA short sale. Once you find and FHA short sale you should check to see if it is a FNMA My Community mortgage in Florida. Florida short sales and FNMA have unique rules. Some of them apply to FNMA flip properties.
The final point I want to make is that FNMA has many mortgage loans available. You can examine FNMA flips all you want but you will need the FNMA MyCommunity mortgage eventually. This is what FNMA short sales are all about.
