A land-home or turnkey label describes a delivery structure, not a universal list of included work. Build the total from the actual documents and keep every omitted or unresolved category visible.
Short answer: A manufactured-home land-home package may combine some or all of the land transaction; home and factory options; freight, delivery, setup, and installation; access, clearing, grading, drainage, and site preparation; survey, design, engineering, foundation, footers, and support; septic or sewer, well or water, electric, plumbing, HVAC, and other utilities; permits and inspections; steps, decks, ramps, skirting, gutters, landscaping, cleanup, corrections, warranties, and closeout; plus financing-related fees, taxes, insurance, reserves, allowances, and exclusions. Do not treat the package total as the completed project total until the written documents assign every relevant category.
