I currently owe a mixed use property which has a commercial on the first floor and two residential units on the upper floors, i live in one of residential unit so that would consider an owner occupied property.

Quote from @Carl Rowles: As a rule of thumb, I prefer to remove any tenant that is currently 20% below market or more.

@Jennifer Brown;  normally I would either seek more info to help out on a posters question or give some direction on your Real Estate Investment path.  

@Nathan Gesner I definitely agree something like 'outdoor soaking tub' would be more accurate, but there isn't currently a searchable amenity title for that, is the thing. 

Have an expert look at it.I understand that you want to avoid setting untreated wood directly on concrete because the concrete attracts moisture that rots the wood. 

Yeah this topic is certainly exhausted.LLCs do not protect you from torts especially if you, the human, is careless or reckless in the direction of the LLC.LLCs can be expensive.

The home is under an LLC however it is not currently being rented out, my grandfather lives there.

Current zoning would prohibit the whole setup actually, but the building and commercial use are allowed to continue as-is because they predate the town's incorporation in 1993. 

If you are wanting to know resale value, zillow.com's recently sold listings can give you direction on that.
