@Charles Burgess To be honest with you, the chances of you buying a lot and building on it for less than the cost of buying an existing property are pretty low.

I want to know if I buy a four plex under an FHA, claiming that one of the units will be my primary residence, can I move somebody into the unit I claim as my residence and collect rent from them without issue? 

The great. thing about the 1031 exchange it is will allow you to sell in Tampa and buy any type of real estate anywhere in the US.Here's one caveat to explore however. 

If the value goes down the tenant doesn’t buy or renegotiates and you lose.

If you were me, would you be looking to buy now or waiting to see how the higher interest rates and end of the pandemic (hopefully) impact prices?

Buy with seller financing with terms that allow a 48-month principal payment of $150,000 and you've achieved your first question.

That way we can buy homes already placed in parks and make cashflow + a down payment and don't require a real estate license.

@John Currey- are you trying to buy a resedential investment property or a  commercial property ? 

I've seen it price many people out who thought that in 2020 it was a terrible time to buy and now regret it immensely. 

I would then plan to use this forced equity (since I plan to buy a fixer upper) to invest in another home.I have been constantly reading to househack right into the MFH, but this may take some time for me to acquire the money and purchasing power.
