If you already have a home, you can rent your current home and move into the purchased home as a primary residence.

You have to be a bit careful on that as the last thing you need is for the lender to find out after the refi and think that you never planned to stay as your primary residence. 

-He live in the residence as required.

I just bought a house that was 100% more expensive than the last primary residence I purchased.

You'll only need 3.5% down, and live in one of the units for 1 year as your primary residence. 

Do you currently have a primary residence?

I am an investor residing in SF Bay Area but started investing in Atlanta market starting this year.

So @Gregory Hatcher you have a primary residence that you are house hacking?

I know folks who go to LV all the time, who love to stay at a residence rather than stay on the strip or downtown.
