Tim hit the nail on the head with what he wrote.All I can tell you is that in my neck of the woods is that finding a Section 8 tenant with a credit score at or above 600 would be like finding one with all their natural teeth. 

IN texas its like 3 bucks a foot in charleston we pay 15 to 20  in Oregon I paid 5.75 last year but that will go up to 7. and this includes window install and nails LOL..

Your first step is to really nail down why your portfolio homes are performing poorly.

For short-term rentals, I would follow the Airbnb workflow model as they have it nailed down, but would also love to learn what others have been using or working through.

@James Hamling  You nailed it .   

Similar to if you hired a company to replace a roof-you don't have a copy of the bill for all of the shingles and nails, but you have a copy of their bill that has those effectively built in.

But, I really need to nail down a plan the is attainable and executable.

A simple example is baseboards: if they're considered permanently attached to the wall like being glued on they're treated as a long life asset, it would damage the wall to remove it so it's like part of the wall; on the other hand if it's easily removable like being tacked or nailed onto the wall it qualifies for 5 year.
