I don’t know anyone that has painted the exterior of a house or replaced a roof.

They're water resistant, can be installed on top of tile and you can find some cheap options for under $1.40 sqft.

Please let me know if any additional information would help paint a better picture.

Replaced floors and paint. 

people who sell like fast closingstime is of the essencemake sure you have an approval letter telling the seller you have the finances to pull off the dealonce you have a letter to show that places the ball in your courttake a couple people with you on the walk through if you are looking at multiple units with a detailed plan of what to look for that may need repairs this will free up your time so you can smooze the seller and get on the ground with the sellermake a list of knownsnew carpet, new paint, drywall repairs, doors cabinet hardware ect... allow so much per unitenjoy

Then, rate the amount of rehab to be done, from "clean & paint" to "move walls & rebuild".

Splash & Dash (paint and light repairs)?  

People take shower some longer than others 365 x 46 x persons the amount of vapor moisture where did they go?

I'd factor in another 10% to cover roof's, water heaters, paint jobs and HVAC.

Solid wood expands and contracts to much with moisture changes to be used over concrete.
