And all areas of the country will have more extreme weather (hotter summers and harsher winters).

I want to say there is quite a bit to do as there are off gas from materials that have absorbed the chemicals in the creating process of drugs.

A few years ago we had a paint body shop with a guy running drugs and chemicals out of it, he got nailed, the place closed, reopened and no real stigma hung for very long.

@Jim Goebel,I'm going to be a bit harsher than some.

Anything will chemicals, detergents, carpet, drape, new car seats can cause more health discomfort and Feds have not tackled them yet. 

I'll probably drop all chemical spreading this year because it's too expensive.

But when he moved out we had a colony of bed bugs that had never been seen before. 12 chemical treatments and 6 heat treatments (I even stopped by the last one and gave the techs $100 bill to crank it to the max) and six months of no rent.

April,  you can due as @Ryan Booth had suggested and use a wire brush or fur out the walls and hang drywall. you could use a chemical stripper to take the paint off, or not go through all that and take a putty knife, or a strong spackle knife that isn't flimsy, and scrape away any loose paint. then try to coat the wall with a layer of drywall mud. if there is loose paint that you missed the moisture from the drywall mud will raise it up. you just take that off and patch it with the mud. that may save you hours of work trying to remove the paint.

@Kristian Fernandez   First thing you should do is get pre-aprroved with a lender.....I used Shawn Huss with Chemical Bank in Ohio.....Until you do that you won't know what you can and can't do.Then determine if you want cashflow,...or appreciation or both......I decided strictly cashflow....and chose Cleveland....flew back to Ohio twice to check out areas and brokers and property managers....2 SFR's and 2 duplxes later I have all 6 of my OOS under Holton-Wise....check them out.

These new systems are so advanced, and they are sensitive to chemicals, such as bleach.
