In terms of rehabbing the property, the workflow can range from throwing a coat of paint on a wall or two, to an entire gut of the mechanicals, windows, siding, and flooring.

I'm going o be a little blunt but this is BP where we don't sugar coat it!

Did you have to dilute it/mix with e.g Flood Floetrol/Penetrol or similar to get a nice and even coating or just used it as-is?

Depending on the wall color in the living area, maybe put a nice coat of light greige there too...if it doesnt clash with the floor etc.

Also don't neglect cleaning all the rad fins as we found this last one coated with dust & dog hair etc etc.

Generally speaking on all of my projects I spend the extra money on good paint because I feel like the cheap paint always fades quickly especially being outside and the Emerald series paint is thicker and does a good job at hiding micro imperfections so it hide sections where the drywall wasn't completely sanded or has swirl marks. 

I have no idea how many times they have been refinished, but before my last tenant moved in I had the downstairs redone for about $1.75/sf, which was full sanding and three good coats of poly.

In theory I could purchase, attempt to rent out with just a few coats of paint, and sell for a profit if I didn't like the numbers. 

I know where I am it is extremely difficult to get paint covered with a SD unless tenant abuse/neglect caused the need for the paint, you can't just use the SD to put a fresh coat of paint on the walls.

Have a wonderful day. have you checked out white coat investor
