Hi Treza,Not sure where you are in the process there, but when your ready to exercise financing options please reach out, it's very difficult to find a ground up program for inexperienced borrowers without having an experienced GC sign on the loan with you which in turn is not easy to find. 

Will he and potential buyer of the property be subject to Commercial financing or will the property still qualify for residential 4 unit and under loan types/primary?

This term replaced "subprime" and looks a lot different than subprime loans of the past.

At the current scenario, without knowing anything about you or your properties I will recommend either to look at a loan from your assets using DSCR loan.

I bought this property with a private interest free loan from a friend. the person i bought it from need cash fast so i offered them a low cash offer and they accepted.I had enough money saved up to rehab the house with my savings.

We did that for about 3 years until Jeff informed me he'd fallen behind on property taxes, and all of his lenders called the loans due.

Hello I am going to sell my primary residence in Idaho and use the proceeds to buy a less expensive home in Oregon without a mortgage loan (all cash).

So we retired the sellers loan within 12 to 18 months.

I have experience in the flip, rental, space and can help with the loan, and the real estate broker piece.

However, consider STR seasonality, local regulations, and management demands, and ensure your equity loan and new primary residence costs fit comfortably within your budget.
