If they move out after 10 years, you will have a had time explaining to a judge that a replacement is beyond normal wear and tear, assuming the tenants would haul you into small claims court.

The house across the street is just now on the market for $374k and about 300 sq feet larger but not as tastefully done.Curious to see what the thoughts are on switching banks (if that would really matter) or somehow appealing the decision or just sticking with the $40k less?  

A finished basement WILL increase the sale appeal of the house.A finished basement CAN be advertised as "square footage" for rent.A finished basement CANNOT be used as above ground living space for appraisals.A finished basement SHOULD NOT but sometimes IS used as "square footage" in MLS listings.I hate the cost of foundations but we determined early on to bite the bullet and always build with basement foundations.  

The resort has many amenities (6 pools, 3 hot tubs, tennis courts, water park, etc.) on a big plot of land(33 acres).

When doing comparables you have to consider the condition of the properties, taking in account the quality and newness of the rehab, and the appeal to renter and potential OO if you are thinking about exit strategies.  

Courts will typically find that said possession is "continuous", "actual", "open and notorious", and "hostile", -as well as quite arguably "exclusive". 

@Matt PfefferlenIt is taken care of by filing a quiet title case in Court.

Note that there is a State statute of limitations on how long the debt is enforceable by court action. 

Make sure it's got curb appeal first and then do interior.
