01The long answer
Yes, but really —
are they any good?
A straight answer, including the parts that aren't flattering. If you only read one page on this site, read this one.
02A short history of a bad reputation
Everything went wrong before 1976. Almost nothing has since.
The reputation attached itself to a product that no longer legally exists. Here is the actual sequence.
- 1950s01
Trailers
Eight feet wide, towed behind a car, aluminium skin, no insulation to speak of. This is the thing everybody is still picturing. It was a vehicle, and it was sold as one.
- 197402
Congress steps in
The National Mobile Home Construction and Safety Standards Act passes after a decade of genuinely alarming fire and structural failures. It creates a federal building code — the only one in the United States.
- 197603
The HUD Code takes effect
June 15, 1976. Everything built after this date is legally a manufactured home, not a mobile home. Fire ratings, wind resistance, plumbing and electrical standards, third-party plant inspection. The industry is a different industry from this morning onward.
- 199404
Wind and thermal zones
Post-Hurricane Andrew. Wind zones II and III introduced with dramatically higher structural requirements, plus thermal zoning that ties insulation to climate. Roof loads, anchoring and glazing all tighten.
- 2021—202505
Energy standards
DOE energy conservation standards phase in, pushing envelope performance past most state codes for site-built housing. Duct leakage testing becomes mandatory. Blower-door verification becomes routine.

Where we actually are
A 2026 HUD-code home from a good plant is tighter, better insulated and more consistently built than the median new site-built house in the same market. This is not a marketing claim; it is what the testing shows.
03Three different things
Manufactured, modular, site-built.
These get used interchangeably and they are not interchangeable. The differences change your code, your lender, your timeline and your price by a factor of three.
| Criterion | Manufactured (HUD) | Modular (IRC) | Site-built |
|---|---|---|---|
| Building code | Federal HUD Code — one standard nationwide | State/local IRC, same as site-built | State/local IRC |
| Where it's built | Indoors, on a jig | Indoors, on a jig | Outdoors, in whatever weather there is |
| Inspection | 9 third-party in-plant inspections | In-plant + local final | 3–6 local inspections, mostly visual |
| Build time | 8–12 weeks | 10–16 weeks | 7–14 months |
| Typical cost / sq ft | $95–135 | $140–190 | $220–380 |
| Chassis | Permanent welded steel | Removable carrier | None |
| Financing | Chattel, or real-property lending on owned land | Conventional construction loan | Conventional construction loan |
| Appreciation | Follows the land and titling | Same as site-built | Same as site-built |
| Lumber rained on | Never | Never | Frequently |
04Energy
The bill is where the argument ends.
Envelope performance is the one claim in this industry that cannot be fudged, because a third party puts a fan in your front door and measures it. Ask for the blower-door result on the specific home you are looking at, here or anywhere else — a plant that tests will produce the number, and one that will not has told you something.
A factory does this better than a job site for an unglamorous reason: the same crew installs the same window flashing detail four hundred times a year under a roof, at waist height, with the wall lying flat on a table.
The HERS index
Lower is betterA HERS rating is the industry's standardised energy score. 100 is a house built exactly to the 2006 reference code. Every point below that is a one percent reduction in modelled energy use.
05Where the sceptics are right
Three things we are not going to talk you out of.
Any dealer who tells you there is no downside is telling you something else too, and you should listen to that instead.
- 01
Financing on leased land really is worse.
A chattel loan on a rented pad runs roughly two points over a comparable mortgage and amortises over 20–23 years instead of 30. Nobody should pretend otherwise. It is why our first question is always about the ground, not the granite.
- 02
Resale is thinner, and slower.
The buyer pool for a home on leased land is smaller and more credit-constrained. Expect a longer time on market than a comparable site-built house. On owned land with a permanent foundation, this evens out almost completely — but it takes a permanent foundation, not a promise.
- 03
The floor is a real floor, but the market's floor isn't.
There are still bad plants and bad dealers, and the price spread between the worst HUD-code home and the best one is enormous. Ask any dealer for the in-plant inspection reports and the blower-door result. If they can't produce them in a day, walk.
06Common questions
The ones we actually get asked.
Legally, no. “Mobile home” refers to anything built before 15 June 1976, when the federal HUD Code took effect. Everything built after that date is a manufactured home, and the two are governed by completely different rules.
In conversation people use the terms interchangeably, and we are not going to be precious about it. But if you are reading a loan document, an insurance policy or a zoning ordinance, that date is the line that matters.
On land you own, with the home on a permanent foundation and titled as real property: yes. Conventional, FHA Title II, VA and USDA all lend on manufactured homes that meet those conditions. On a leased pad you are in chattel lending, which is a real loan with real underwriting — just more expensive. Which situation you are in is a decision you make, and we would rather you made it on purpose.
The same as any other house: as long as the roof and the envelope are maintained. HUD-code homes from the early 1980s are still in service across the country. The structural failures people remember are almost entirely pre-1976 units, or post-1976 homes that were never properly anchored — which is a set-crew problem, not a construction problem.
Every home is certified to a wind zone, a roof-load zone and a thermal zone, all printed on the data plate inside the kitchen cabinet. New Mexico is Wind Zone I and Thermal Zone 2 under the HUD Code, so a home built for this market is engineered to the inland wind standard and the middle insulation requirement. Roof load is the one that varies here: a home going up at Sandia Park or Cedar Crest is carrying snow that a home in the valley never sees, so ask which roof-load zone a particular home is certified to before you commit it to the mountains.
Anchoring is engineered and torque-tested, and it matters more than any of the above. A properly anchored home on engineered piers performs comparably to a site-built house on a stem wall; the failures people remember are almost always homes that were never tied down correctly.
Usually — it is what most of our buyers are doing. The constraints are zoning (Bernalillo, Sandoval, Valencia and Santa Fe counties each handle manufactured housing differently by district), any minimum square footage or roof-pitch covenant on the parcel, physical access for a load up to 16 feet wide on a single section and half a double at a time, and utilities. Call us with the parcel and we will go through it with you before you spend anything.
With a permanent foundation, a continuous perimeter, a site-built porch and a conventional roof pitch — generally not, from the street. Several of the double-section homes on the lot are built for exactly that, and the difference between one of those and the same plan set on blocks with vinyl skirting is mostly what you spend on the ground under it. Whether it matters to you is a personal question, and a completely reasonable one.
Still not convinced?
Good. Come and be unconvinced in person — it takes about twenty minutes and a flashlight.
