Modular and Container Home Construction Loans
Last updated: October 29, 2026. Checked against Fannie Mae, HUD, and South Carolina sources listed below.
Yes, you can usually finance a modular home with a construction-to-permanent loan. Fannie Mae treats modular homes the same as site-built homes, as long as the home is real property, sits on a permanent foundation, and meets local building codes. Container homes are harder to finance. Fewer lenders offer them, the home needs an engineered design approved by your building department, and the appraiser needs enough comparable sales to support the value.
What is the difference between modular, manufactured, and container homes?
| Home type | Built to | How lenders usually treat it |
|---|---|---|
| Modular | State-adopted building code, the same code as site-built homes | Like a site-built home when it is real property on a permanent foundation |
| Panelized or prefab kit | Local building code | Like a site-built home |
| Manufactured | HUD's federal manufactured home standards (24 CFR Part 3280) | Separate rules: HUD label, permanent foundation, titled as real property |
| Shipping container | Engineered design under the building code's container rules | Case by case. Many lenders don't offer it. |
The key difference is the code. A modular home is built in a factory to the same residential code as a site-built home. A manufactured home is built to HUD's federal code and carries a HUD label. If a seller calls a home "modular," check which label it has.
How does a modular home construction loan work?
A modular build usually uses the same construction-to-permanent loan as a site-built home:
- You apply with your lot, plans, and the modular builder's contract and budget.
- The lender approves the builder (often the local dealer or general contractor who sets the home) and orders an "as completed" appraisal.
- You close before work starts. In South Carolina, an attorney supervises the closing.
- Draws pay for site work, the foundation, the modules, setting, and finish work. You pay interest on the money drawn so far.
- After the final inspection and certificate of occupancy, the loan converts to your permanent mortgage.
Factory deposits are the main difference. Many modular factories want a deposit before they build the modules. Ask each lender how it handles factory deposits and when it releases money for the modules. Read how construction loan draws work.
What do lenders require for a modular home?
Fannie Mae says modular, prefabricated, panelized, and sectional homes must (Fannie Mae B2-3-02):
- be built with the same quality of materials as site-built housing
- be legally classified as real property
- meet all local building codes where the home is placed
- be permanently attached to a foundation, with any wheels, axles, and tow hitch removed
Fannie Mae also says modular homes must be built under the International Residential Code as administered by the state. It has no minimum width, size, or roof pitch for modular homes, and the appraiser doesn't have to use modular homes as comparable sales (Fannie Mae B4-1.4-02).
FHA and VA can also finance modular construction through lenders that offer it. See FHA construction loans for modular homes and VA construction loans for modular and manufactured homes.
How does South Carolina certify modular homes?
South Carolina runs a Modular Buildings Program through the SC Building Codes Council. The state says the program applies the same construction codes as site-built homes. It also requires modular manufacturers to be licensed and to use independent, third-party inspection agencies to certify the buildings (SC LLR Modular Buildings Program).
Each modular unit must have a Council certification label before it leaves the factory. The label is assigned to that specific unit, often on the electrical panel cover, and can't be transferred to another unit (S.C. Code Regs. 8-614). Your lender, appraiser, or building inspector may ask to see it.
A modular home still needs a building permit and, if there's no sewer, a septic permit. See construction loan requirements in Upstate South Carolina.
Can I get a construction loan for a shipping container home?
Sometimes, but expect fewer options. Here is what usually stands in the way.
The code path
Newer editions of the model building codes added rules for shipping containers. The 2021 International Residential Code points container homes to Section 3115 of the International Building Code for structural design. The International Code Council also publishes ICC G5-2019, a guideline for repurposed shipping containers. It is a nonmandatory guideline, not a code. In practice, you'll usually need plans from a licensed engineer or architect and approval from your local building department.
The appraisal
The appraiser has to support the home's value with comparable sales. In many areas, few container homes have sold. That can make the value hard to support, so some lenders decline the loan or ask for more equity.
The lender
Container homes rarely fit standard loan programs. Banks and credit unions that keep loans in house are often the most likely to consider them. Ask early whether a lender has closed a container home before.
What should I do before I apply?
- Confirm with your county that the home type is allowed on your lot and under any deed restrictions.
- Get the factory or designer's plans, specs, and a full budget, including site work, foundation, setting, and finish work.
- For modular, confirm the manufacturer is licensed in South Carolina and the units will carry a state label.
- For container homes, get engineered plans and ask the building department what it needs.
- Ask lenders about factory deposits, draws, and builder approval before you sign with a factory.
Frequently asked questions
Can I use a construction loan for a modular home?
Often, yes. Many lenders finance modular homes with the same construction-to-permanent loan used for site-built homes, as long as the home is real property on a permanent foundation and meets local codes.
Is a modular home the same as a manufactured home?
No. Modular homes are built to the same state-adopted code as site-built homes. Manufactured homes are built to HUD's federal standards and carry a HUD label. Lenders treat them differently.
Can I get a mortgage on a shipping container home?
Sometimes. Fewer lenders offer it. You'll usually need engineered plans approved by your building department, and the appraisal must be supported by comparable sales.
How do I know a modular home meets South Carolina rules?
Check for the SC Building Codes Council certification label. South Carolina requires a label on each modular unit before it leaves the factory.
Do modular homes appraise like site-built homes?
Fannie Mae treats modular homes like site-built homes and doesn't require modular comparable sales. Value still depends on the home's quality, location, and local sales.
