So we now have a private loan that we are going to refinance into a regular mortgage. 

You'll need at least some reserves.What you want to find are hard money lenders, and/or private money lenders. 

I set up a Corp in the fall prematurely (with the intent of private investors) , cost a few grand but now I have it and I can keep it until I’m ready for that.

Not impossible though.I have private lenders who loan small amounts like this for a year at a time, but they have reasonably high risk tolerances and a whole lot of trust in me as a borrower.

When I graduated college my father was into comm'l real estate and was a licensed broker and he taught me a little bit.The main thing to do is to educate yourself and once you decide what you want to do, focus on that style you pick out 1 or 2 areas and make sure you know them well. 

Style and age are different.Are there cash buyers that buy this stuff?

Perhaps you can send me a private message listing the company you worked with to see if there service MI as well.

Please feel free to PM me if you'd rather go private.

Provide self-directed IRA funds in the form of a note (private money) and find like minded flippers in the same situation with IRA money to invest to then fund my flips. 

All are brick ranch style houses.
