2) Move forward with the formal eviction process, wait for a judgement, then take back over?

Sun, wind, rain, moss growth, hail, snow, etc.If it looks dirty or has green moss growing on the north facing side, it might be worth a cleaning...If the shingles are sliding out of place or look like they are starting to curl on the ends, it might be worth a little maintenance.Outside of that, If no leaks, leave it alone.

This was after 5 days of constant hard rain, flooding everywhere.

The issue was: when it rained it poured.  

This was after the foundation was given the OK by 2 separate inspectors and occurred due to lack of support under the house, soft soil in Florida, and lack of gutters to disperse rain water from the foundation.

@Brian H.Only one way: experience lol so either you know someone you have worked with or you find someone who has one they have used and you trust their judgement.  

There are all sorts of reasons why it may have sold for 2k. all that matters now is what it's worth it to you today.some reasons-buyer paid taxes or judgements etcthere were title issuesit was a buy out of a family or biz partnerthe last seller was a crack headgeneral distressed sale and a seller that didn't carethe property was in far worse shape than it is now

The house is built into a hill (I don't know what the term is for that), so where it has rained, that's become a problem for the lower level.

The chemical would go straight down and then run along the bedrock till it would come out when it rained or the ground got saturated. - The property was torn down and is now on the Florida Super Site fund for clean up - when they get the money.

The good news is, because it is such a common problem due to our clay-based soil expanding and contracting with the rains and heat, it's a pretty competitive field.
