Manufactured Homes on Land in Snohomish County

The fifteen acre property I have listed on 252nd Street NE in Arlington has a triple-wide on it, built in 2004 and set on a poured concrete foundation. That detail matters, because a permanent foundation is one of the first things a buyer's lender asks about on a manufactured home.

Manufactured homes on their own land are common across rural Snohomish County. They also come with a set of rules that often nobody explains until a loan runs into them. This is the explanation, in advance.

The words matter

• Mobile home usually means a factory-built home made before June 15, 1976, when the federal HUD construction code took effect. Financing one is very difficult, and that shapes who can buy it.
• Manufactured home means one built to the HUD code on or after that date. Each section carries a red certification label on the outside, and there is a data plate inside, often in a closet, a cabinet or near the electrical panel. Lenders want to see both. If a label is missing, a label verification letter can be ordered from IBTS, the organization that keeps those records for HUD, which makes it a fixable problem.
• Modular or factory assembled homes are built to the state building code rather than the HUD code and carry a state insignia. Lenders and appraisers generally treat them like site built houses, even though they also arrived on a truck.

Single-wide, double-wide and triple-wide describe how many sections were joined on site. Multi-section homes generally have more financing options than single-wides.

“A manufactured home starts out titled like a vehicle.”

Real property or personal property

This is the question that decides most of what follows. A manufactured home starts out titled like a vehicle. As long as it stays that way it is personal property, separate from the land under it, and financing it on its own usually means a personal property loan rather than a mortgage.

Washington lets an owner eliminate the title under RCW 65.20 once the home is affixed to land owned by the same person. After that, the home and the land are one piece of real property, which is what mortgage lenders generally require.

Before you buy or list one, find out which it is. The county assessor's record and the title company can tell you whether the elimination was ever done. If it was not, it can often be taken care of as part of the sale, and it belongs in the agreement as a term rather than a surprise. The NWMLS has a Manufactured Home Addendum for this part of the transaction.

The foundation

Skirting around a home sitting on blocks and piers is not a permanent foundation, however tidy it looks. FHA requires the home to sit on a foundation that meets HUD's permanent foundation guide, certified by an engineer, and other lenders have foundation requirements of their own.

A home on a poured concrete foundation, like the one on 252nd, starts from a strong position. A home on piers may need an engineer's inspection and sometimes retrofit work, which is a real cost and a real delay in escrow. If you are selling, find out where your home stands before listing. If you are buying, make it part of your feasibility contingency.

Financing, and who will lend

Once the home is real property, on a permanent foundation and built after the 1976 line, several of the common loan types come back into play. FHA and VA both finance manufactured homes on land that meet their rules, conventional programs have manufactured home guidelines of their own, and USDA has a manufactured home option in eligible rural areas. Rules differ by program and change over time, so ask a lender how they apply to the specific home.

Three things still trip people up:

• Age. The federal line is 1976, but individual lenders can set later cutoffs. Ask the lender, not the internet.
• Appraisal. Appraisers compare a manufactured home with other manufactured homes, not the site built house down the road, and on rural property those comparable sales can be scarce. That can hold a value down even when the home is well kept.
• Moves. A home that has been moved from the site where it was first installed is a problem for FHA and for some other lenders. Ask whether the home is on its original site, and get the answer in writing.

If the home cannot be made real property, the buyer is looking at separate financing for the home and the land, or cash, and the price should reflect that smaller pool of buyers.

Buying one: what to inspect

Everything a normal inspection covers, plus a few things particular to factory-built homes: the marriage line where the sections meet, moisture under the home and in the floor, the tie-downs and anchoring, the roof and the water heater, and any additions built on site, like decks, porches, carports and extra rooms, which may or may not have permits.

Then there is everything that comes with rural land regardless of the house: the well, the septic system, the access and the zone. That checklist is in Buying Land and Acreage in Snohomish County, and from November 1, 2026 the septic inspection is required before every sale of a property with septic in the county.

“The seller who does well with a manufactured home is the one whose paperwork is in order before the first showing.”

Selling one: get the file together first

The seller who does well with a manufactured home is the one whose paperwork is in order before the first showing. That means the title elimination record, the HUD labels and data plate located and photographed, the foundation paperwork, permits for anything added on site, the well and septic records, and plain facts in the listing about the year, the manufacturer and the number of sections.

Price it against other manufactured homes on land that have closed, not against a site built house with the same square footage, because that is what the buyer's appraiser will do. The rest of how I price and market rural property is in Selling Acreage and Rural Property in Snohomish County.

Replacing an old home with a new one

Plenty of buyers look at a worn-out older single-wide on a good parcel and see the land, not the house. That can be a smart purchase. Under RCW 36.01.225 a county cannot regulate the placement of a manufactured home more strictly than a site built home, though it can require a new home on a permanent foundation. The county still permits the placement, the septic system has to suit the new home, and the old one has to go. If it is being hauled away on public roads, Washington requires a permit carrying the county treasurer's certificate that its property taxes are paid, under RCW 46.44.170. Budget for all of that and it works. Assume it is free and it does not.

Common questions

Can I get a conventional loan on a manufactured home?

Often, if it is real property, on a permanent foundation, built after June 15, 1976 and meets the program's other rules. Single-wides and older homes narrow the options. A lender who does these regularly can usually tell you in one phone call.

Is a 1978 manufactured home financeable?

It is on the right side of the federal line, so FHA and VA are possible if the foundation and title are right, but some lenders set their own age limits. Expect fewer options and a closer look at condition.

Does a manufactured home on land go up in value?

The land does what land does here. The home itself tends to hold its value less well than a site built house, so much of the appreciation lives in the ground and in improvements like the shop, the well and the septic system. That is worth understanding when you decide how much to spend on the house compared with the parcel.

What does title elimination involve?

An application to the state, proof that the home is affixed to land owned by the same person, any lender on the home agreeing to it, and recording with the county. Title and escrow companies handle it regularly during sales.

Do you work on these, or just houses?

Both. The 252nd Street property is a manufactured home on fifteen acres, and it is on the Portfolio page with the rest of my listings and closings. If you are shopping for one, the property search on this site covers the full Northwest MLS, and my Google reviews are clients' own words.

The bottom line

A manufactured home on its own land is a good way onto acreage in this county when the title, the foundation and the age line up with what lenders require, and a frustrating one when they do not. All three are knowable before you write an offer or put up a sign. Find out first, fix what can be fixed, and price honestly for what cannot.
