However, I already had my primary residence at that point.

One side is their primary residence, the other side is a rental. 

I only look to this exit when my primary buyers pass on a deal (if they are interested, I pay an agent a flat fee to conduct my business)....My primary buyers pass a lot on deals because they are buy n hold investors, so the numbers are different than fix n flip numbers.

@David Flores You can use FHA loan for primary residence only up to 4 units.

Parys booked a three day weekend into the unit and everything seemed fine, she was in the area trying to find a long term place and wanted to experience the area, not totally unusual.On the second day she sent a message through the platform asking to extend for a full two weeks, which, ok, nice!

It was my primary residence for 7 years until I moved out last August.

I did do a cash out refi ~6 years ago, but it was in conjunction with capturing an improved interest rate on our primary residence.

Consider that as a primary home and rent out your existing home.

My primary question is one of "business" or "commercial" rental income tax (currently Ohio State). 

Care to share which platform this was to warn us?
