If you've got to do a mobile, you know the risks go ahead and do it. As said it won't be a money making venture, the mobile part the land different story. We started out in a 1965 Pontiac Chief! lmfao I chit you not that was the brand of the mobile. We bought it used for cheap lived in it for around 7 years and ended up giving it to a hippy but he had to pay to move it away.

Another thing to pencil out if the zoning isn't an issue is start small with stick frame. I know of guys that started out slapping up a garage real quick, living in it for a while then building a house on to it and moving in the house then using the garage for... a garage. Know another guy that built a shell with a tall bay door one side that he drove a 5th wheel into. He lived in that and over time finished off the shell in to rooms bit by bit as cash flow allowed. The end game obviously loose the 5th wheel and completely finish it all into a house. Just another option to chew on
