Can you do a 203k on a manufactured home... Yes. How about this. You want to replace your manufactured home... use the existing pier and post foundation and document it. We suggest that you make your "mark" on the existing piers so they can be identified under the new home. Years ago we had a lot with 3 pier and posts on the lot in the rubble after the city razed the homes on that block. HUD was contacted and we were given permission to build a home on that portion of the foundation and those piers were put just inside the crawl space access door so they could easily be found. The manufactured scenario is very similar in concept. Just be sure to use as many of the piers as you can.
