Financing a Modular Home or Barndominium in Florida: What Actually Works
The loan type that works for a standard modular home won't work for a barndominium — and most buyers don't find that out until they're already in contract. Here's what lenders actually require and how to approach financing before you pick a builder.

The key distinction:
A HUD-code modular home can be financed with a conventional mortgage, FHA, or VA loan — just like a site-built home. A barndominium usually cannot. The building code it's built to determines what loan products are available, and that decision is made long before you talk to a lender.
HUD-Code vs. IRC: The Code That Controls Your Loan Options
Every modular and prefab building is built to one of two codes. Which one it uses determines what mortgage products are available to you — often more than the building's price or your credit score.
HUD-Code (IRC-compliant modular)
Built to the same International Residential Code as a site-built home. Treated by lenders as real property once permanently affixed to a foundation.
Loan options available:
- ✓ Conventional (Fannie Mae / Freddie Mac)
- ✓ FHA (3.5% down)
- ✓ VA (0% down for eligible veterans)
- ✓ USDA Rural Development
- ✓ Construction-to-permanent loans
Barndominium / Metal Building
Built to agricultural or commercial construction standards. Lenders classify these differently — and most conventional and government-backed lenders won't touch them.
What typically works:
- ✓ Portfolio lenders (local banks / credit unions)
- ✓ Farm Credit / AgCredit (if agricultural use)
- ✓ Construction loans from regional lenders
- ✗ Conventional / FHA / VA — usually declined
- ✗ Most national mortgage lenders
This is the single most important financing question to answer before you fall in love with a floor plan. If you need VA or FHA financing, you need to build to IRC code — which typically means a modular home, not a barndominium.
Construction Loans vs. One-Time-Close: Which Is Right for You
Even if your building qualifies for standard financing, new construction works differently than buying an existing home. You'll likely need one of these two structures:
Two-Close Construction Loan
You get a short-term construction loan to fund the build, then refinance into a permanent mortgage once the building is complete and appraised. Two separate closings, two sets of closing costs.
Pros
- • More lender flexibility
- • Can shop for best permanent rate at close
- • Good if build timeline is uncertain
Cons
- • Two closings = two sets of fees
- • Rate risk on permanent loan
- • More paperwork and timeline
One-Time-Close (OTC) Construction Loan
One closing that covers both the construction phase and the permanent mortgage. The construction loan automatically converts to a permanent mortgage once the build is complete. Popular with VA and FHA programs.
Pros
- • One set of closing costs
- • Rate locked at start
- • Simpler process overall
Cons
- • Fewer lenders offer it
- • Less flexibility mid-build
- • Rate locked even if rates drop
VA Loans and Modular Homes in Florida
VA loans can be used for modular homes — but there are specific requirements that trip veterans up. The building must be permanently affixed to a foundation, titled as real property (not personal property), and built to IRC residential code. The VA also requires a VA-approved appraiser to assess the property, and the appraiser must be able to find comparable sales in the area.
Key VA requirements for modular homes:
- •Must be permanently attached to a foundation (not on wheels or piers without permanent attachment)
- •Must be titled as real property, not personal property — this requires surrendering any vehicle title
- •Must meet local building code and pass VA appraisal
- •Comparable sales within ~10 miles are required for the VA appraiser — rural lots can be a challenge
- •A VA one-time-close construction loan is available through approved lenders — not all VA lenders offer this
Financing a Barndominium: Where to Actually Look
Barndominiums are classified as agricultural or mixed-use buildings by most lenders, which puts them outside of conventional lending guidelines. That doesn't mean financing is impossible — it means you need to go to the right lenders from the start.
Portfolio lenders
Local banks and credit unions that keep loans in-house instead of selling them to Fannie/Freddie. They can write their own guidelines. Many in rural North Florida have experience with barndominium financing.
Farm Credit / AgCredit
If your property has agricultural use (even minimal), Farm Credit lenders can finance both the land and the building together. AgCredit has Florida offices and specific barndominium programs.
Land + construction package
Some lenders will finance the land purchase and construction together as a single loan if you don't own the land yet. Ask specifically for a "land and construction loan" — not all lenders offer this structure.
Cash-out refi on existing property
If you have equity in an existing home, a cash-out refinance can fund a barndominium build on a separate parcel. Simpler underwriting since the loan is secured by your existing home.
What Lenders Need Before They'll Approve
Whether you're financing a modular home or a barndominium, lenders will want most of the same things. Getting these ready before you apply moves the process significantly faster.
- ✓Builder contract with scope of work and fixed price
- ✓Floor plans and specifications
- ✓Lot survey and legal description
- ✓Builder's license number and proof of insurance
- ✓2 years tax returns + recent pay stubs
- ✓Proof of land ownership or purchase contract
- ✓Construction draw schedule from builder
- ✓Appraisal based on comparable completed properties
The Appraisal Problem — and How to Avoid It
Construction loans are typically based on the appraised value of the completed property. But if comparable sales for your type of building don't exist within a reasonable radius, the appraisal can come in low — killing the loan or forcing you to cover the gap in cash.
This is most common for barndominiums in areas where few have been built and sold. Rural North Florida is improving on this as more barndominiums get built, but it's still a real risk. Before you commit to a lender, ask: "How do you handle appraisals when comparable sales are limited?" Their answer tells you a lot about their experience with this type of construction.
To protect yourself on appraisals:
- • Ask your builder for addresses of 3–5 completed similar builds in the area that have sold
- • Work with a lender who has actually financed this type of build before — not just one willing to try
- • Don't over-customize in a way that makes appraisal comparisons impossible
- • Get the appraisal early in the process — before you're committed to a builder and schedule
Talk to the Lender Before You Talk to the Builder
The sequence matters. Know what you can finance and on what terms before you fall in love with a floor plan or sign anything with a builder. The builders we connect you with understand Florida construction lending and can refer you to lenders who have actually closed these deals — not just ones willing to try.
