Speaking from a Realtor's point of view, my concern would be if, and when, you want to sell, do you think your home will be more valuable than when you purchased it. My experience for 24 years has been, it is much more difficult to sell a manufactured home than to buy one new. The values seem to depreciate instead of appreciate.
I would recommend checking out the homes available for sale in the area before committing to purchasing a manufactured home. It might surprise you by the time you spend for all of the upgrades to a manufactured home versus a stick frame home built on site. For future value, you should really do your homework before investing your money in any home.
