How long do you have to live in a FHA acquired property?

[Sean MIddleton]

I have heard several people use FHA and 203k loans to buy investment real estate. I currently have a home and am using a HELOC for capital to start investing. I live in my home with my with my wife and son. Knowing that I have to "live" in a property to qualify for FHA/203k loans, I noticed investors have either lived in as secondary property or lived in short term before renting the property out. What are some common strategies to use FHA/203k for individuals that currently have a home they live in? Is this possible?
