| 1. Manufactured home | About $80,000–$200,000 for the home; land and setup usually extra. | Check insulation, heating and cooling capacity, roof-load rating, and wind-zone requirements for the site. | In the U.S., homes built to the federal HUD Code have a separate code pathway from locally built homes. Zoning, foundation, tie-down, and installation rules still apply. | Financing options can depend on whether the home is titled as personal property or real property and whether the borrower owns the land. | Often several weeks to a few months after ordering; transport, site readiness, and inspections affect the schedule. |
| 2. Modular home | About $100,000–$300,000 for the home, depending on size and finish level; site costs extra. | Factory-built sections can be engineered for local snow, wind, seismic, and energy requirements when specified in advance. | Generally must meet the state and local building code applicable to the site. Confirm plan approval, foundation design, and inspections with the local authority. | Construction-to-permanent financing may be available, subject to lender approval, appraisal, contractor arrangements, and site documentation. | Factory production may take a few months; foundation work, transport, assembly, and finish work add time. |
| 3. Panelized home | About $100,000–$250,000 for a typical home package; installation and site work vary. | Wall and roof panels can be specified for local insulation, moisture management, wind, and snow needs; correct on-site sealing is important. | Usually reviewed under local building codes. Confirm the permit set includes structural details, energy documentation, and foundation plans. | Lenders may treat it as new construction; clarify how package deposits, staged payments, and contractor responsibilities fit the loan. | Panel production can take weeks to a few months; site assembly commonly takes additional weeks, depending on scope and weather. |
| 4. Structural insulated panel (SIP) home | About $120,000–$300,000 for a home package; finishes, labor, and site costs are additional. | Continuous insulation can help reduce air leakage when joints are properly detailed. Specify moisture control, ventilation, and fire protection for local conditions. | Confirm that the local building department accepts the proposed structural system and has the required engineering, product, and energy documents. | Typically financed as a site-built project, but lender approval depends on the builder, construction budget, appraisal, and draw schedule. | Panels are often made to order; factory lead time and on-site completion together can span several months. |
| 5. Pre-cut house kit | About $50,000–$180,000 for a materials package; labor, foundation, and finishes are usually separate. | Climate performance depends on the chosen wall, roof, insulation, and window specifications—not the kit format alone. | The owner or builder generally needs locally approved plans and permits. Check structural loads, energy code, and who is responsible for engineering. | A kit purchase alone may not qualify for a standard mortgage; ask lenders about construction loans and required licensed-builder involvement. | Kit delivery may take weeks to several months; build time depends heavily on crew availability and owner participation. |
| 6. Post-and-beam or timber-frame kit | About $100,000–$300,000 for a structural package; enclosure, interior work, and site costs are extra. | Large open spaces may need careful heating and cooling design. Specify insulation, condensation control, and suitable roof structure for local weather. | Requires site-specific structural design and permits. Confirm local requirements for connections, fire safety, energy performance, and foundations. | Construction financing is common, but lenders may want a complete cost-to-finish budget and an experienced builder. | Fabrication often takes several weeks or months; raising the frame can be quick, while enclosure and finishing take much longer. |
| 7. Shipping-container conversion | About $30,000–$150,000 or more for a conversion; transport, engineering, insulation, and site work can raise the total substantially. | Steel conducts heat and cold, so insulation, thermal bridging, ventilation, and corrosion protection need careful design. | A container is not automatically an approved dwelling. Local officials may require engineered plans, building-code compliance, and zoning approval. | Some lenders may view conversions as nonstandard construction; confirm eligibility, appraisal approach, and insurance before committing. | A simple conversion may take a few months; permitting, custom fabrication, and site access can extend the timeline. |
| 8. Tiny house on wheels | About $30,000–$100,000 or more, depending on size, materials, and whether it is professionally built. | Small interiors heat and cool quickly; insulation, condensation control, plumbing freeze protection, and weight limits matter. | Rules vary widely. A vehicle or recreational-vehicle classification does not necessarily allow full-time residential use; check zoning, parking, and sanitation rules. | Traditional mortgages may not apply. Personal-property or vehicle-related financing may be possible, depending on classification and lender rules. | Custom builds commonly take several months; delivery and placement depend on road access, towing limits, and local approval. |
| 9. Prefabricated accessory dwelling unit (ADU) | About $80,000–$250,000 for the unit; foundation, utility connections, permits, and site work may be significant additions. | Choose insulation and mechanical systems for the local climate; consider drainage, access, and protection from heat, wind, snow, or wildfire exposure. | ADU permissions depend on local law, lot conditions, setbacks, height, parking, utility capacity, and building-code review. | Possible options include cash, a home-equity product, or construction financing. Eligibility depends on property value, lender rules, and project documentation. | Factory production may take a few months; approvals, utility connections, access, and site preparation often determine the overall schedule. |
| 10. Prefab cabin or log-home package | About $50,000–$200,000 for a package; completed-home costs depend on labor, insulation, utilities, and finishes. | Check snow and wind loads, roof design, moisture management, ventilation, and thermal performance. Log walls may need ongoing inspection and maintenance. | A cabin or seasonal-use label does not automatically waive building rules. Verify occupancy classification, access, sanitation, and local permits. | Financing may be more complicated for remote, seasonal, or owner-built projects; ask lenders about access, utilities, insurance, and construction experience. | Package delivery can take weeks to months; remote access, weather, foundation work, and skilled labor can extend construction. |
