If it has a central air unit, it must be legally disconnected and the Freon or chemical recovered.Taxes must be paid, and lot rent if located in a park.Then you are ready to move the "free" home.

I find my own FSBO on Zillow and FSBO sites, but you can buy them from Redx as well.You will get a lot of wrong numbers and disconnected ones.

I'll be paying a licsensed master electrician I trust to verify the work and set the new meter and disconnect.

After driving for dollars and finding the owners we either find no number for them, a disconnected number, or they are not interested in selling.

Also I send periodic texts to remind them about things like disconnecting their hoses for winter or sidewalk maintenance, etc. 

There is a separate hydro meter run for it but it is disconnected because the owner said something about animals chewing the electrical wires in the attic.

I then called every number on it and they were all disconnected as the company went out of business.  

I went back by and found that someone had pulled the manual disconnect rope.  

Then if tenants want it on they can pay for it or you can disconnect. 

I’ve seen the water company disconnect the pipe at the street when the house was winterized.
