Manufactured Homes and ADUs in Austin: 2026 Financing Rules
On September 1, 2026, a new Texas law changes where manufactured homes can go. Senate Bill 785, passed in the 2025 legislative session, requires every Texas city with zoning to allow new HUD-code manufactured homes by right in at least one residential district, according to the Texas Manufactured Housing Association. For Austin-area buyers staring at a metro median sales price of $416,000 (Team Price Real Estate, August 21, 2026, month-to-date figure), that opens a door. Manufactured homes and homes with accessory dwelling units (ADUs) are two of the most practical paths to a lower payment in Central Texas, and both come with financing rules that surprise first-time buyers. This post walks through two composite buyer scenarios to show how the money side actually works.
Key points:
- SB 785 takes effect September 1, 2026. Cities with zoning must allow new HUD-code manufactured homes by right in at least one residential district, and they cannot single those homes out with special permits they do not require of other housing in the same category.
- A manufactured home can use FHA or conventional financing when it sits on a permanent foundation and is titled as real property.
- FHA asks 3.5 percent down with a 580 or higher credit score (most lenders want 620). Fannie Mae’s standard manufactured program asks 5 percent down, and its MH Advantage option can go as low as 3 percent for homes with specific construction features.
- FHA lets buyers count 75 percent of an existing ADU’s market rent toward qualifying income, capped at 30 percent of total monthly income (HUD Mortgagee Letter 2023-17).
- The statewide ADU bill (SB 673) died in the Legislature, but Austin’s own HOME rules still allow additional units on many single-family lots inside the city.
- Homes on leased land or with personal-property titles need chattel loans, a different product with different costs.
What does Texas SB 785 change on September 1, 2026?
SB 785 requires every Texas city that has zoning to permit new HUD-code manufactured homes by right in at least one residential zoning district. Cities also cannot demand a specific use permit for a manufactured home unless they require one for other housing in that same district. Cities still decide which district qualifies and how large it is, but they can no longer exclude manufactured housing entirely.
The practical effect for buyers around Austin is more legal placement options over time, especially in suburbs and smaller cities that previously zoned manufactured homes out. The law covers new homes built to the federal HUD code, the construction standard in place since June 15, 1976. It does not override deed restrictions, so a subdivision with a recorded restriction against manufactured homes keeps that restriction. Check both zoning and deed restrictions before you fall in love with a listing.
A buyer scenario: the math on a manufactured home near Austin
Consider a composite buyer we will call Dana, an operations manager earning $68,000 a year with a $280,000 ceiling on what she wants to spend. Site-built resale homes at that price are scarce inside the metro. Where her search gets traction is with newer manufactured homes on owned land in outlying communities such as Kyle, where listings pairing a HUD-code home with its own lot commonly price well below the metro median tracked on our Austin housing market page.
Dana finds an existing double-section home, built in 2022, already installed on a permanent foundation on a half-acre lot, listed at $265,000. Because the home is affixed to the land and titled as real property, she can finance it with a regular mortgage. On FHA, her minimum down payment is 3.5 percent, about $9,275, subject to credit, income, and property qualification. Her property taxes and homeowners insurance escrow into the payment the same way they would on a site-built house.
Two cautions from her file. First, the appraiser must confirm the home has its HUD certification labels and was never moved from a prior site (FHA requires the home to have been transported directly from the manufacturer or dealer to its current site). Second, resale values for manufactured homes depend heavily on the land under them, so owned land in a growing corridor matters as much as the home itself.
How do you finance a manufactured home with FHA or a conventional loan?
A manufactured home qualifies for FHA or conventional financing when it was built to the HUD code on or after June 15, 1976, carries its HUD certification label on each section, sits on a permanent foundation of durable materials, and is titled as real property rather than personal property. In Texas that means the owner has filed a Statement of Ownership with the state’s manufactured housing division electing real-property status. Once those boxes are checked, the loan works much like any other mortgage.
| Requirement | FHA | Conventional (Fannie Mae) |
|---|---|---|
| Minimum down payment | 3.5% with a 580+ score | 5% standard; 3% via MH Advantage on qualifying homes |
| Home requirements | HUD label, built on or after June 15, 1976, at least 400 sq ft, permanent foundation | HUD label, permanent foundation; MH Advantage adds construction-feature requirements |
| Title status | Real property | Real property |
| Mortgage insurance | 1.75% upfront plus annual MIP | PMI, removable once you reach 20% equity |
| Occupancy | Primary residence | Primary; limited second-home options |
The dividing line to watch is the title. A home in a leased-land community or one still titled as personal property cannot use these programs. That situation calls for a chattel loan, a product Ferrando Financial does not originate, and chattel financing typically carries higher rates and shorter terms than a real-property mortgage. If you are choosing between two similar homes and one sits on owned land with a real-property title, the financing alone can make it the better buy. Our FHA overview for Austin buyers covers the broader program rules that apply here too.
Can ADU rental income help you qualify for a mortgage in Austin?
Yes, on FHA loans. Since HUD Mortgagee Letter 2023-17 took effect in late 2023, a buyer purchasing a home with an existing accessory dwelling unit can count 75 percent of the ADU’s appraiser-documented market rent as qualifying income, as long as that rent makes up no more than 30 percent of the borrower’s total monthly effective income. Conventional treatment is narrower: Fannie Mae counts ADU rent only on its HomeReady program, and Freddie Mac allows it with documentation conditions.
Here is a second composite scenario. The Trans, a couple with $9,000 in combined monthly income, are looking at a 1960s East Austin house with a detached garage apartment. The appraiser’s rent schedule puts the ADU’s market rent at $1,400 a month. On FHA, 75 percent of that, $1,050, can be added to their qualifying income, well under the 30 percent cap. That extra income raises the loan amount they can support (a debt-to-income ratio, or DTI, measures monthly debts against monthly income) without changing what they earn at work. At Mortgage Austin we see ADU income turn marginal approvals into comfortable ones, though every file remains subject to credit, income, and property qualification.
The unit has to be a real ADU: a separate living area with its own kitchen, bath, and entrance that is legal on the lot. Projected rent from a unit you hope to build someday does not count for a standard purchase loan.
What the Legislature did not pass, and what Austin already allows
The 2025 session also considered SB 673 and HB 2480, which would have required cities statewide to allow ADUs on single-family lots. Those bills died, so there is no statewide ADU mandate. Inside Austin city limits, though, the HOME amendments the city adopted in 2023 and 2024 already allow up to three units on many single-family lots, which is why garage apartments and backyard casitas keep showing up in Austin listings. Smaller-format ownership is expanding on a second front as well: the state’s small-lot rules, which we covered in our Texas small-lot laws buyer’s guide, push starter-home sizes down in big-city suburbs. The common thread is more lower-cost paths to ownership, each with its own financing fine print.
Frequently Asked Questions
Can I get an FHA loan on a manufactured home in Texas?
Yes, if the home was built to the HUD code on or after June 15, 1976, has at least 400 square feet, keeps its HUD certification labels, sits on a permanent foundation, and is titled as real property. FHA allows 3.5 percent down with a 580 or higher credit score, though many lenders look for 620. Approval is subject to credit, income, and property qualification.
Do manufactured homes qualify for conventional loans?
Yes. Fannie Mae’s standard manufactured housing program requires 5 percent down, and its MH Advantage program allows as little as 3 percent down on homes built with specific features such as higher-pitch roofs and attached porches. The home must sit on a permanent foundation and be titled as real property.
How much of my ADU’s rent counts toward a mortgage?
On FHA loans, 75 percent of the appraiser-documented market rent for an existing ADU can count as qualifying income, capped at 30 percent of your total monthly income under HUD Mortgagee Letter 2023-17. Conventional rules are narrower: Fannie Mae counts ADU rent only on HomeReady loans, and Freddie Mac allows it with conditions.
Does SB 785 mean I can put a manufactured home on any lot in Austin?
No. Starting September 1, 2026, cities with zoning must allow new HUD-code manufactured homes by right in at least one residential district, but each city still chooses which district that is. Deed restrictions also still apply. Check the zoning map and the subdivision’s recorded restrictions before you buy.
What if the home is on leased land or in a manufactured home community?
A home on leased land or titled as personal property needs a chattel loan rather than a mortgage. Chattel loans typically carry higher rates and shorter terms, around 20 to 25 years. Ferrando Financial originates Conventional, VA, and FHA real-property mortgages only, so a chattel purchase would come from a specialty lender.
Is a manufactured home cheaper than a site-built starter home near Austin?
Usually, yes, on the structure itself. Listings that pair a newer HUD-code home with owned land in outlying Central Texas communities often price $100,000 or more below the Austin metro median of $416,000 (Team Price Real Estate, August 21, 2026, month-to-date). Total value depends heavily on the land, location, and the home’s condition and title status.
