Should we consider a lawsuit?

[Alexander Schloe]

Friends, 

We recently bought a STR in GA and it seems like we walked into a mess not disclosed by the sellers or picked up on the inspection report.

For example, after closing we walked in to find: 

water in the basement and clearly evident water damage (disclosure said water intrusion eight years ago, resolved and repaired). 

Septic tank inspected and rated for 3 beds (Disclosure rated for 4 beds) 

Septic tank covered by flagstone walkway and addition of house and walkway needs to be torn up to access it, pump it, and add riser 

Flying squirrels in the attic and eating electrical/closet door. Rats in the basement eating electrical (Disclosure: No pests or animal intrusion) 

 We bought from afar so we are partly at fault but I certainly cast some blame on the inspector (who picked up none of the above) and sellers for not being honest on disclosure. I understand that litigation is expensive but, at what point is it worth it? 

Thanks for your thoughts and time!
