An older mobile home already has site work, utility and sewer hook-ups, but may need major updating. A new trailer does not need fixing, but the land needs to be purchased, site work needs to be done and utilities need to be hooked up. Really not interested in leasing the land or the mobile home. Looking to do this the most economical and cheapest way possible, money is very tight, and the mobile homes seem very affordable.You are better off buying the location with the existing trailer on it , all other things being equal, the cost of providing those services to another site could equal the cost of a good condition newer trailer. You could either replace the trailer at a later time for not a huge amount (Double check the zoning and planning board rules on this) or you could use it as a building site for a moduler or stick built home as well.
