Quote from @Jeff Calcaterra: We have a potential tenant new to the area who has gone through a paid background check, signed a background check authorization form, sent us a LinkedIn profile, sent an offer letter and says he is willing to send us paycheck stubs, but says he doesn't want us to call HR to verify employment because he is supposed to have found housing already.

We would buy this house all cash. 

If you decide to keep your house, you can do an IRRRL after you have made at least 7 payments on your new mortgage.

I'm having a very hard time with them and on the verge of losing my earnest money on a house purchased to flip.

It will be remote, but since you live there now, you probably already have connections who either already know the house or local friends to find you good people to service things as needed.  

I started off with 3 houses on a lot and another house two lots down.

Quote from @Pearse Cafiero: You want to borrow money to buy a house, but you don't have the downpayment.

They will tear your houses up man lol.

I built a house and it’s going to be difficult to sell as I have no equity in it because of Cost to build.

@Tim Holt, Yes INDEED house hacking is the best option for most 1st time buyers.
