By definition, these type of loans are not the same quality as what is traded on wall street. 

did half the flip work, sold with new walls and new electric/plumbing.

I mistakenly assumed that was an error because the place didn't have an official street address yet.

Windows would be my next check-point (less than R1) and then wall insulation: I would not be surprised if they have no insulation inside, but you can do blow-in, which only requires a small hole.A home looses heat in two ways: heat conduction (which you can slow down with insulation) and drafts, which in old houses is usually the biggest culprit.

This has pluses and minuses.If your property is bulletproof such as no framing - cinder block construction, cement floors, gloss white paint slapped on the walls and a cheap window mount AC, then you are in a prime position to make money with S8. 

Anything that involves a load bearing wall will generally need an architect IME, but it can also be required (maybe indirectly) through the jurisdiction's building code/enforcement.Got it, thank you for lending your expertise!

It tends to hide marks better.Walls: Neutral tones like SW Repose Gray, Behr Swiss Coffee, or Moore Classic Gray are renter-friendly and modern.Trim and Doors: Use a crisp white like SW Extra White or Moore Chantilly Lace.Accent Walls: For a touch of style, consider an accent wall in soft blue-gray. 

We have zip codes that have lower and and higher end areas within the same zip so not a good marker to use.Going along with that a lot of the neighborhoods are very street by street or change pretty quickly by block, so you have to be aware of that.

It's not fully closed as in drywall, it's sort of a faux wall on our side, but the tenant could open the door on his side and come through if he wanted.

I don't know what your budget looks like but this city is really inconsistent or "street by street."
