Wondering if anybody has invested with American Homeowner Preservation out of Chicago? 

If there is a minor stain in need of cleaning that gets missed they can take care of that.

Your tenants need to buck up and take care of the bugs.

Remember, this is still a sales type of business so be very careful on who you choose to work with.

@Sebastian Tamburro you're going to get advice/offers from numerous people trying to profit off you - be careful!

So if I was dealing with a seller who was insisting on handling the transfer this way, I would be wondering what the seller is trying to hide... and I would figure it out.

Since they notified you of this, you should get it taken care of as your insurance may not cover a claim if there is an accident because it was a known defect.

I wonder how involved would I still have to be if I hired representation?

Better to have your own property manager use trusted handymen to take care of the issues for long term/quality fixes. 

I am wondering if there is any market in New Jersey, New York, Pennsylvania, Rhode Island, Connecticut, Maryland, or Washington DC that would "make sense" to house hack given my financial position?
