Once you've unequivocally claimed your property from your neighbor -then start gathering the facts (how long has he used the property exclusively, what can he prove, what can you prove, survey if needed) and reviewing the law to see who is likely to prevail if the matter goes to court. 

Or can he just be a member of the LLC with 100%/0% split. 

Can he explain the process, create timelines, organize info like books on cloud storage, etc.4) Gut feel, does he treat you like you're worth his time. 

Can he take the loan out without being the owner of the property?

@Sisiley Bao I was one of the people who suggested those areas which was related to someone who works in Plymouth which is on the west side of the Twin Cities.

Can he stay beyond his lease date?

Can he get insurance money and not fix and still sell me the house? 

If he isn’t employed in someway how can he have expenses for you?

I don't know if he'd go for a credit at close, but tenants can he bought :)Still wouldn't close without a majority of interiors being given a look see and it's only 5 minutes (barring roof/crawl access).

Can he sue me for the entire amount of the initial deposit or only the difference?
