If it is an older home in the "Rose District" and has a crawl space, I'd probably find a GC to take a look to lift and shim as needed.

If you have a web site, or info. please share.

I live in Pennsylvania and on the web I found that the Court house has a  Judicial Tax Sale, and a Repository List, the repository list has bids for homes/trailers that is only $250 per bid.

What makes you say they can not crawl from or to other units?

Right now I am thinking of just picking a company based on web reviews .. is that a good idea?

My friggin back yard (crawling with ants) is competitive.It is all relative. 

They may need to seal up where they are getting in and leave some bait in crawl space (if you have one)This will get you off to  a good start with your new tenants by showing that you are going to take care of issues promptly.
