One deed and one lien means one loan, so the split has to happen before anyone builds. You cannot buy one 10-acre parcel on a single FHA loan, put four homes on it, and carve it into four mortgages after the fact. To end up with four separate payments, the land has to be legally divided into separate parcels, each individually owned and financed, before construction starts. FHA does offer a one-time-close construction loan that buys the lot and funds the build in a single transaction. On acreage, FHA sets no fixed limit; the constraint is appraiser judgment. The appraiser has to exclude excess land (land beyond what serves and supports the home) from the appraised value, and a property whose value is dominated by the land can fail FHA's marketability standards. That makes a residential construction loan a poor vehicle for financing a big block of raw land. Program details change, so confirm the current one-time-close requirements. The workable paths for a group: - Each person buys an already-split parcel. Roughly 2.5 acres apiece if you are dividing 10, with each doing their own one-time-close construction loan on their own lot. - Buy the full 10 acres in cash, legally subdivide, then build. Only after the split does each person build and finance individually. One FHA loan on the whole tract with plans to unwind it later is the version that does not work.
