Look like you would be able to charge for repainting crayoned walls as this is not normal wear and tear. 

I was currently thinking about a light gray walls with white trim and ceilings.

Four years ago we saw the writing on the wall on this so I started working with other cities in the area and compiling lists of where STR is legal (and there are plenty of spots to invest in Volusia county that should have great returns, you just have to know where). 

There wouldn’t be much structural change, maybe just making the family room a bit bigger by removing a wall, otherwise it would all be cosmetic renovating.

If you move anything, walls, plumbing, electric, get a permit.

There are many institutional investors from Wall Street that buy single family homes.
