Yes, you can sell it.Sometimes Peoria will grandfather a duplex and refer to it as a "legal nonconforming" single family zoned property with duplex as permitted use.If this is the case the new owner will be able to legally and officially use it as a duplex.I have also heard of people finding an architect to declare that the house was originally built as a duplex, which would help you get it rezoned as multi-family and duplex as permitted use.PM me for more info.

Hey!!! I have religiously listened to the BiggerPockets Pod cast for a long time and even read some of the books. Today, i have finally joined and looking to learn and connect.Alex

The taxing officials realize that there is no one around to protest these sorts of increases, so it is always attractive fruit to pick. 

This officially puts you on title as the owner. 

I am curios if you declare anything to the city after you did that for the official record ?

I suspect that preserving the occupancy tax cash cow weighs on county officials more than the concerns of their constituents up at the lake.Don’t get me wrong, I’m not complaining.  

*BUT* - when I was in the Navy, I had lots of apartments, but my "official" residence was always my ship.

XXXXXXXXXXX, in book, page, of the Official Records of the County of Los Angeles County, State of California;WHEREAS, the Trustee does hereby reconvey, without warranty, to the person or persons legally entitled thereto, the estate now held by the Trustee under said Deed of Trust.Dated 1/17/2013Trustee: ReconTrust CompanyBy: Maria Fregin, Assistant Vice PresidentState of Arizona, County of Maricopa.....and then below all that, it is notarized.

The thing is, at this point in analyzing a property I'm not really wanting to make an official offer yet.

So the three types of zones aren't "official" per se, so I would advise speaking with people who would know i.e. realtors, investors, property managers, others hosts, etc. and simply asking them what the medium to long term outlook is on STR regulation in that zone is.
