Yesterday I received my property value statements.  The value is made of 2 components, Land and Building.  Every property I own, the land (or lot) was worth about $2000 in 2018.  On this years statement, every lot is ...

Zillow, County Assessor, etc.

He's not lying in that yes, you can make a lot of money.

I currently have no kitchen and no bathroom sink; I had it demoed before I moved in and because a contractor told me I had black mold from water damage--it was a lie but the mold did look nasty--ultimately no black mold and no asbestos.

I'm pretty sure he lied to my face. 

If the seller lied both about the deposit and the amount of rent and you have the estoppel agreement, there is a bigger problem. 

Unfortunately, my Property Management experience lies more in HOA and Condominium Association management, so I'm not sure how much it helps. 

Take the Parcel ID and look up at the assessors site.

I would get an estoppel letter (after you have a contract in place) to confirm the rent, security deposit, etc are all agreed upon and there isn’t any confusion/lying.
