Title company wants to charge us $300 to do it but his divorce decree states that if he sells the house, which was a double wide destroyed in the Harvey hurricane, then he would owe her $25,000 but it states that the property goes to him. 

If your newly subdivided lots are 150 feet wide and you have 50' setback requirements, then you can build a 50' wide house. 

I had to connect all of the dots and learned a ton about moving double wides!

If you cast too wide a net, you'll just get pulled all over the place.
