A VA Interest Rate Reduction Refinance Loan on a manufactured home carries a 0.5% funding fee for non-exempt borrowers and a maximum term of the original VA loan term plus 10 years, capped at 30 years and 32 days. The controlling threshold is that the borrower already has an eligible VA-backed loan on the property. VA Pamphlet 26-7, Chapter 7, and the VA real-estate-loan definition in 38 CFR 36.4301 address the manufactured-home and real-property requirements that applied when the underlying VA loan was originated. An IRRRL streamlines that existing loan rather than opening the program to a newly eligible property.
That distinction sets the boundary for everything below. An IRRRL replaces a VA loan the veteran already holds, usually to cut the rate or move from an adjustable rate to a fixed one. A unit financed outside the VA program cannot enter through an IRRRL. But a valid existing VA loan involving a leasehold or other nonstandard land arrangement is not automatically excluded merely because the borrower does not own the lot outright. The lender must confirm that the existing VA loan and security remain eligible. The VA’s IRRRL page states the central rule: the product refinances an existing VA-backed loan.
The seasoning test is a later-of rule, not 210 days from first payment
The shorthand “210 days from first payment” gets the statute wrong. Under 38 U.S.C. 3709, the note date of the new IRRRL has to fall on or after the later of two dates. The first is 210 days after the due date of the first monthly payment made on the loan being refinanced. The second is the date on which the sixth monthly payment is made on that loan. A veteran clears seasoning only when both conditions are satisfied, so a loan can pass the 210-day mark and still be too early if six payments have not yet posted.
This matters most on newer loans where payments were made ahead of schedule. Counting six actual payments, not six calendar months, is the operative test. The manufactured-home classification changes none of this; the seasoning rule reads identically for a stick-built refinance.
Recoupment runs 36 months, and three things are excluded from the math
The recoupment test in 38 U.S.C. 3709 requires that fees, closing costs and expenses charged to the borrower be scheduled for recovery through the lower monthly payment within 36 months after the date of loan issuance. The statute uses “date of loan issuance,” so this article does not substitute the note date for that wording. The recoupment figure is the covered costs divided by the reduction in the monthly principal-and-interest payment.
Not every dollar counts against that 36-month window. The statute excludes taxes, amounts held in escrow and fees paid under chapter 37, which include the section 3729 VA funding fee. VA guidance also excludes prepaid or per-diem interest and escrow-type prepaid expenses such as insurance, special assessments and homeowners association dues. Lender and third-party charges the borrower pays to close remain inside the numerator. On a manufactured-home IRRRL those charges can include a foundation or property review if a lender requires one, which raises the numerator and can make a marginal rate reduction fail the test.
Funding fee: 0.5% for non-exempt borrowers
The IRRRL funding fee is 0.5% of the loan amount for borrowers who are not exempt, per the VA funding fee schedule on the funding fee and closing costs page. The rate is the same regardless of whether the security is a manufactured home or site-built.
Statutory exemptions apply. VA lists borrowers receiving compensation for a service-connected disability, borrowers entitled to that compensation but receiving retirement or active-duty pay instead, surviving spouses receiving Dependency and Indemnity Compensation, service members with a qualifying proposed or memorandum disability rating before closing, and active-duty Purple Heart recipients among the exempt categories. Exemption status is confirmed through the Certificate of Eligibility and VA’s systems, not asserted by the borrower. Confirm current exemption categories and the fee percentage against VA directly, since the fee table is set by statute and has changed on prior effective dates.
Term limit: original term plus 10 years, capped at 30 years and 32 days
The maximum IRRRL term comes from VA Pamphlet 26-7, Chapter 6. VA’s November 2024 Chapter 6 update notice links the current chapter: the original term of the VA loan being refinanced plus 10 years, not to exceed 30 years and 32 days. A veteran refinancing a loan that started as a 20-year note can extend to 30 years under this rule. One that started at 30 years stays capped at 30 years and 32 days.
The purchase and chattel term caps in 38 CFR 36.4204 that apply to manufactured-home purchase loans do not govern a standard IRRRL. Chapter 6 controls the streamline term, and that is the figure to use when running the recoupment and payment math.
Appraisal and credit underwriting: the VA baseline, then overlays
VA’s Lenders Handbook treats the IRRRL as a streamline that ordinarily does not require a new appraisal or a full credit underwriting package. The VA IRRRL page separately confirms that the product refinances an existing VA-backed loan.
Lenders and the investors who buy their loans can require more. A lender may order an appraisal, ask for evidence about the foundation, pull credit or run a property review before it will close a manufactured-home IRRRL. Those requirements are overlays: conditions added by the lender or investor above the VA floor, not VA program rules. Overlays vary by lender and change over time, so the correct assumption is to ask each lender what it requires rather than to budget a specific cost or timeline in advance. This guide does not attach a price or a turnaround to those requests because VA does not set them and they are not uniform.
Foundation and documentation questions
Foundation status can still surface as a documentation question because the manufactured-home and real-property requirements applied to the underlying VA loan. The engineering reference is HUD’s Permanent Foundations Guide for Manufactured Housing, Guidebook 4930.3G. It describes the design and inspection criteria a professional engineer applies when certifying a foundation. It is a HUD guidebook, not a VA form.
VA does not universally require a fresh foundation certificate, a new data-plate or label verification, or a site-move history on every IRRRL. What drives a documentation request is the existing loan and property file combined with whatever the lender’s or investor’s overlay policy calls for. A file that already contains foundation evidence may satisfy a lender; another lender may ask for current documentation. Ask the lender in writing which documents from the original file it will accept before ordering any new inspection.
Manufactured versus modular
Modular homes and manufactured homes are built to different standards, and borrowers sometimes misidentify which they own. Manufactured homes are built to the federal HUD Code and carry a HUD certification label. Modular homes are built to state or local building codes and do not carry that label.
The classification affects which VA guidance applies, so it is worth confirming against the original loan file and the certificate of occupancy. Beyond that, this guide does not claim a fixed appraisal or term outcome for either type, because those results depend on the loan being refinanced and on lender requirements rather than on the manufactured-versus-modular label alone.
Questions to put to the lender before you commit
Confirm each of these in writing before ordering any inspection or paying an application fee:
- Is the existing mortgage an eligible VA-backed loan, and does the lender confirm that its current security and property documentation support an IRRRL?
- Does the loan clear the later-of seasoning test under 38 U.S.C. 3709: at least 210 days past the first payment due date and at or beyond the sixth consecutive monthly payment made?
- Will the estimated closing costs recoup within 36 months after excluding the funding fee, escrow, prepaid or per-diem interest and qualifying escrow-type prepaid expenses?
- Is the borrower exempt from the 0.5% funding fee, and is that confirmed on the Certificate of Eligibility?
- What term will the new loan carry under the original-term-plus-10-years rule, capped at 30 years and 32 days?
- Does the lender require an appraisal, foundation evidence, a credit pull or a property review as an overlay, and which documents from the existing file will it accept?
Getting overlay answers in the first conversation tells you whether a given lender can close the file before you spend anything.
