We provide a three page "Move Out Guidelines" which details the cleaning required, from pulling out refer and cleaning behind/under it, to polishing faucets and other metallic surfaces to eliminate water spotting and fingerprints.

To address his fears/worries, I brought in a remediation company to run HEPA filters and wipe down horizontal surfaces.

Look up the manual for your stove's model number, and it will probably have a "clearance required to noncombustible surface" section - see what that says about clearance behind the stove. 

These lots are all adjoining and about the same and the purchase price was exactly the same on all three.

you are putting up 655K and getting back gross 26.4k per year , in the surface this is 4%, but actually if your condo assoc decides that they need new windows and hits you with a 12,000 assessment you are screwed.

Second, the price at $245k doesn't appear to be a stellar price, from the surface.

I see how having 'everything taken care of for you' appears attractive on the surface, but then the underbelly gets exposed.  

Breaking into the drywall to repair the leak exposed a small amount of surface mold that is apparently from a slow leak before we bought the property.  

I generally agree on the surface, but would love to see the actual source.Per Brookings Institute, there are several matching metros, but some are different. 

This price will of course be higher if you have an unusual roof design with greater surface area.
