I would structure as a 12 month deal with (2) extensions. 

Extensive experience with this group. 

For most it would involve extensive reading of web sites like this and books.

What would be the estimated cost to fix the issue if it isn't extensive and can be accessed (I am assuming dry rot in garage the way it is described).

I'm in the Bay Area so a bit tough for me to hang out in the area for extensive period of time. 

We are coming down next week to look at some projects in Philadelphia from Monday to Wednesday but we will be driving by Cleveland after that.Or you yourself or do you know of any entrepreneurs, active developers, or people who do have extensive knowledge of the Cleveland real estate market for investing? 

That is reasonable to ask for a 2 day extension.

Ive informed them I would be renovating the apartment extensively.

You need to do extensive due diligence to make sure the turn key company is legitimate and a good business decision.

One of the big HOA managers in town retired a few years back and left his kids to run it, the downfall has been noticeable in communities they run (which is many of them). so do extensive due diligence.
