Panelized Home Financing: What Lenders and Appraisers Look For
Module Building Systems
Panelized home financing follows the same path as financing a site-built home. Fannie Mae's Selling Guide says panelized housing "is not considered manufactured housing" and gives it "the same treatment as site-built housing," as long as the home meets local building codes and is permanently attached to a foundation.
Module Building Systems (MBS) builds wall, floor and roof panels for homes in our St. Louis plant. Panelized homes are still a small slice of new construction. NAHB's analysis of Census data, published Oct. 21, 2026, counts about 16,000 single-family homes built with panelized or precut methods in 2025, out of 975,000 completed. In the Midwest, 5% of completed single-family homes used modular or panelized methods.
So the loan officer on your file may not have handled one before. Settle the manufactured-home question in the first call.
Is a panelized home considered a manufactured home?
No. A panelized home is not a manufactured home under Fannie Mae's rules. The Selling Guide, section B2-3-02 (updated Feb. 4, 2026), defines a manufactured home as a dwelling built on a permanent chassis with a HUD Data Plate and HUD Certification Label. A panelized home has neither.
The difference is in how the house is built and approved. Manufactured homes are built to HUD's federal code, traditionally on a permanent steel chassis. A panelized home is built to the building code adopted where it sits. It gets a local permit and local inspections, the same as a house framed on the lot.
Panelized construction is a way of building where wall, floor and roof panels are framed in a factory, shipped flat to the lot and set on the foundation. The Census Bureau's construction definitions describe a panelized house the same way: "A package of wall panels, roof trusses, and other components is shipped from a factory to be assembled on site."
Our homes are conventional wood framing, with 2x6 exterior walls at 16 inches on center and structural sheathing. There is no chassis and no HUD label. Our panelized vs. modular vs. stick-built guide compares all three.
Can you get a mortgage on a panelized home?
Yes. Fannie Mae makes loans on panelized homes eligible under its rules for one-unit properties, the same rules a site-built house follows. The guide sets three conditions: the home is built with the same quality of materials as site-built housing, it meets all local building codes where it sits, and it is permanently attached to a foundation that meets local code.
Conventional loans carry most new-home purchases. NAHB reported on Oct. 26, 2026 that conventional financing covered 67.6% of new homes sold in 2025, down from 69.3% in 2024. FHA-backed loans and cash purchases each covered 13%, and VA loans 4%. Those shares cover every new home sold, built by any method.
Your lender can add its own requirements on top of Fannie Mae's, so ask before you apply. Use the word panelized with your lender and your appraiser.
How do appraisers value a panelized home?
Appraisers value a panelized home by comparing it with recent nearby sales, the same method they use for a site-built house. Fannie Mae's appraisal section for factory-built housing, B4-1.4-02, says comparable selection works generally the same way as for site-built homes. It does not require a comparable sale of the same factory-built type.
That matters on an infill lot, where the closest sales are often older brick homes on the same block. Those sales stay in play.
Fannie Mae also sets no minimum width, size or roof pitch for these homes, so a panelized design does not have to look like a box. The Wren in our catalog is an 800 sq ft, two-bedroom, one-story home on a 25 by 32 ft footprint. The same panel system builds The Mason, a two-story, three-bedroom city home on a 22 ft wide footprint, and the three-story townhomes of The Brickline.
Quality still drives value. The guide asks appraisers to learn the features that affect quality and to report them. Hand your appraiser the plans and the wall section, and point out that the panels were cut and framed on our CNC line from shop drawings built off the project's BIM model.
How does a construction loan work for a panelized home?
A construction loan pays for a panelized home in draws, as it does for a site-built home, but the panels are made in our plant before they reach the lot. Ask your lender at the start how it funds components built off site. A draw schedule written for a site-framed house assumes the framing happens on the lot.
The order of work helps here. We price the panel package from permit-ready plans, and the fixed-price quote is valid for 30 days. You submit for permit once scope and price are set. We start manufacturing after the permit is approved, and the factory panel price stays fixed from contract through delivery. While we build the panels, your GC completes the foundation to our tolerances.
Construction-loan interest runs for every month the loan is drawn, so the schedule matters. Panelized projects can deliver up to 50% faster construction schedules compared with traditional construction. Actual schedules depend on project scope, approvals, site readiness, materials and logistics. Our carrying-cost table shows what a shorter build can mean in loan interest per home.
Show the lender who does what
At MBS, the agreed package defines factory completion. We supply framing subcomponents, bare framed panels and sheathed panels. More complete assemblies may include windows, doors, cladding, insulation or MEP rough-ins when specified. Your quote identifies the factory inclusions and the work retained by your site team. Your GC sets the panels and completes the building, including foundations, site work, utilities and interior finishes. We install only by agreement.
What your lender needs for panelized home financing
- Permit-ready drawings, then the permit once it is issued
- Our fixed-price quote, with the factory inclusions and the work your site team keeps
- Your GC's contract for the foundation, the panel set and the finish work
- The written warranty, which you can request with the estimate
- The site address, so freight is priced into the estimate
Ask your insurance agent to start builder's risk coverage before the first truck arrives.

Frequently asked questions
Is a panelized home the same as a modular home?
No. The Census Bureau defines a modular home as finished three-dimensional sections built in a factory and joined on a permanent foundation. A panelized home ships as wall panels and other components that are assembled on site. Fannie Mae treats both like site-built housing, but modular homes must be built under the International Residential Code as administered by the state.
Do I need a construction loan to build a panelized home?
Usually, yes, if you are building on your own lot. The home does not exist yet, so a construction loan funds the work in draws and a mortgage takes over when the home is finished. Ask whether your lender offers a single-close construction-to-permanent loan and how it handles factory-built components.
What should I tell my lender about a panelized home?
Call it panelized: conventional wood framing, built to local code and permanently attached to a foundation. Point the loan officer to Fannie Mae Selling Guide section B2-3-02, which covers panelized housing. Then send the permit-ready plans, our fixed-price quote and your GC's contract, so the lender sees the full scope and who builds each part.
Who inspects a panelized home?
The building code adopted where the home is built governs it. In Missouri that means local plan review and local inspections, the same path a site-framed house takes. Panel connections stay open to view until interior finishes go on, so the inspector sees the work before it is covered.
How long is an MBS panel quote good for?
Our fixed-price quote, prepared from permit-ready plans, is valid for 30 days. Once you sign, the factory panel price stays fixed from contract through delivery, even if lumber or labor costs move. That gives your lender a firm number for the panel package when it sets the construction budget. Freight within our 1,000-mile standard range is priced into the estimate.
