We are wrapping up our annual reviews of the various housing segments in the Portland, Oregon region with a consideration of manufactured homes. We will restrict our attention to manufactured homes permanently affixed to land that is also owned by the same party. This means we are excluding classic mobile home parks where the owner of the mobile home must pay a lease/lot rental fee.
If you missed the previous annual reviews covering single-family detached homes, condominiums, and attached homes, you may click this link.
Let’s define the Portland Region as the following six counties: Columbia, Clackamas, Hood River, Multnomah, Washington, and Yamhill—essentially all counties contiguous with Portland’s home county of Multnomah, plus Yamhill.

DATA HOUSEKEEPING
The information in this post will be based on properties that sold on the open market, defined as listed in RMLS, the primary multiple listing service for the Portland Region. The data was parsed with tools created by the blog author to weed out/correct, among other things, listing errors and misclassifications (e.g. manufactured homes hiding in other categories, such as the detached category). RMLS has a listing category, SNL, Sold Not Listed, that allows agents to put properties that were sold off market into the database. Those properties have been excluded from the following analyses.
WHAT IS A MANUFACTURED HOME?
The U.S. Department of Housing and Urban Development provides the following definition and conditions for FHA mortgage insurance:
Manufactured Housing is a Structure that is transportable in one or more sections.
To be eligible for FHA mortgage insurance as a Single Family Title II Mortgage, all Manufactured Housing must:
• be designed as a one-family dwelling;
• have a floor area of not less than 400 square feet;
• have the HUD Certification Label affixed or have obtained a letter of label verification issued on behalf of HUD, evidencing the house was constructed on or after June 15, 1976, in compliance with the Federal Manufactured Home Construction and Safety Standards;
• be classified as real estate (but need not be treated as real estate for purposes of state taxation);
• be built and remain on a permanent chassis;
• be designed to be used as a dwelling with a permanent foundation built in accordance with the Permanent Foundations Guide for Manufactured Housing (PFGMH); and
• have been directly transported from the manufacturer or the dealership to the site.
The definition comes from the HUD manual (4000.1) and helps to differentiate manufactured homes from other type of prefabricated housing, such as modular homes or tiny homes. Fannie Mae essentially follows the HUD definition. Once a manufactured home is brought to the site, they state in their Selling Guide:
The towing hitch, wheels, and axles must be removed. The dwelling must assume the characteristics of site-built housing.
The manufactured home must be attached to a permanent foundation system in accordance with the manufacturer’s requirements for anchoring, support, stability, and maintenance.
The foundation system must be appropriate for the soil conditions for the site and meet local and state codes.
The manufactured home must be permanently connected to a septic tank or sewage system, and to other utilities in accordance with local and state requirements.
Manufactured homes are built in a factory and must meet the minimum guidelines established by HUD. While modular homes are also built in a factory in sections, they are not meant to movable beyond the initial transportation from the factory and have their final construction and assembly at the site and are placed on a permanent foundation. Modular homes have more stringent guidelines and building codes and are more expensive as a result.
Tiny homes, are just that, tiny. They usually don’t meet the minimum square footage requirements for manufactured homes and are often left in a transportable state; that is, they are relatively easy to move to another location. (Not a plus for collateral underwriting.) While there may be state or local ordinances, there are no federal guidelines for them and they are generally considered personal property. Getting them financed through typical mortgage channels is very difficult to nigh impossible.
So, to recap: we consider manufactured homes to be factory-built one-family dwellings that meet HUD guidelines and are permanently affixed to the land and the land must be under the same ownership. To be eligible for general financing, the manufactured home must have been built on or after June 15, 1976. The RMLS database does have a few properties in the manufactured category that were constructed before the cutoff date; those properties, while not meeting the modern requirements for manufactured housing, have been left in the dataset. Often they are not financeable, but they usually convey to the buyer the right to put a replacement manufactured dwelling or single-family home. That can be important, as there are some land parcels (mostly farmland) with zoning that does not allow residential use outright and will only permit an exception dwelling if the site has had continuous residential use (grandfathering the use in). That old manufactured home on a site could make a world of difference in the property value of an acreage lot!
Okay, so that was a lengthy preamble, let’s dive into some stats!
Portland Region 2024 Manufactured Homes Overview

The following table compares 2024 with 2023:

Total dollar sales volume dropped about 9% in 2024 but this is largely a function of the total number of sales declining about 11%. Looking at the composition of sales for each year, 2024 had manufactured homes nearly the same size and age as 2023, but on lots about a half acre smaller. This points to a slightly stronger year per unit sold in 2024, which is reflected in higher average prices, median prices, and price per square foot.
New construction was only 1% of the market and bank repossessions were steady each year and represented less than 3% of the market.
Let’s dive into the rest of the data with some visuals.
SALES VOLUME
The following is a treemap of manufactured home sales volume in the Portland Region for the year 2024:

Clackamas County had almost twice as many manufactured home sales than the next largest county. This is not surprising as Clackamas County is 1,868 sq. mi. and has a lot of farming activity. The second largest county by sales volume, Yamhill, is also known for its rural areas and extensive agriculture.
Sales followed a bell curve (with October being the exception); the market generally peaked during the summer months:

As the following graph shows, 2023 beat 2024 in sales volume eight out twelve months:

SALES PRICE
Prices were fairly level for most of the year:

2023 and 2024 were very close in average prices each month:

CUMULATIVE DAYS ON MARKET
The average cumulative days on market was about two months for the entire year of 2024. Marketing time varied erratically, with no pronounced seasonality pattern:

While the average marketing time in 2024 was only up about 3 days compared to 2023, some months sharply diverged from each other. Variation like this is to be expected when the dataset is so small each year:

HOUSING SUPPLY
Housing supply tracks how long would it take the market to exhaust all available inventory at the current rate of absorption. For most of 2024 the months of housing supply for manufactured homes was above 4 months:

2024 was significantly above 2023 in months of housing supply during the spring and summer months, while 2023 was higher in the fall:

MISC STATS
Before concluding our overview of the Portland Region as a whole, let’s look at some miscellaneous stats:

The highest price for a manufactured home in 2024 is shared by two properties. A manufactured home in Estacada, Oregon and one in Newberg, Oregon. Both closed for $1,125,000.
The home in Estacada was built in 1998, sits on 19.8 acres, and is 1,976 sq. ft. The property has outbuildings. Photos of the home are currently available online and may be viewed here.
The home in Newberg was built in 1981, has a 9.4-acre lot, and is 1,920 sq. ft. The manufactured home was in average shape. The principal component of value for this home was the dividable lot (three parcels). After the sale the manufactured home sold again in 2025, this time for only $595,000 and the lot was only 2.5 acres. Photos of the home are currently available online and may be viewed here.
The least expensive manufactured home in 2024 was a property in Clatskanie, Oregon, which is in Columbia County. The property sold for $143,000. This was an older manufactured home that predates the HUD cutoff date and therefore could not be financed and closed as a cash sale. The home sits on a 1.58-acre lot and is only 744 sq. ft. The structure looks like it is at the end of its useful life, so this was essentially a land sale. Photos of the home are currently available online and may be viewed here.
The most expensive ZIP code for manufactured homes in 2024 was 97132. This area takes in parts of Newberg. While only 4 sales occurred in 2024, the average price was about $741,000:

The ZIP code with the highest volume of sales was 97038:

This ZIP code is in Clackamas County and covers nearly 131 sq. mi. A total of 27 manufactured home sales occurred in this ZIP code in 2024.
A manufactured home in Sandy, Oregon with an 80-acre lot took the crown for the largest site in 2024. The home is a newer unit, with a manufacture date of 2021. The home is 1,836 sq. ft. and has quality interior upgrades. The site appears to be a former tree farm. While not the most expensive sale of the year, this manufactured home did rank #5 on the list! Photos of the home are currently available online and may be viewed here.
The largest manufactured home to sell in 2024 was a property in Dayton, Oregon, which is in Yamhill County. The unit was 2,813 sq. ft. and was manufactured in 2007. The home sits on a 5-acre lot. Given the average size for a manufactured home in 2024 was a little over 1,600 sq. ft., this one would be considered quite spacious. (Photos of the home are currently available online and may be viewed here.) The following histogram shows the distribution of square footage for manufactured homes in 2024:

Approximately 84% of all manufactured homes sold in 2024 are under 1,950 sq. ft.
Let’s wrap up this post with a quick look at the individual counties comprising the Portland Region.
Multnomah County 2024 Stats
Multnomah County contains most of the City of Portland. A sliver of the City of Portland is located in Clackamas and Washington counties. The following table summarizes important metrics for Multnomah County:

Multnomah County saw a nearly 6% drop in the sales volume dollar amount. The total number of sales dropped almost 19%; the reason the sales volume dollar amount did not drop more is due to the average size of the units sold increasing as well as the lot size. Marketing time increased almost 27%. The new construction and distressed categories had almost no activity.
Washington County 2024 Stats
Washington County contains many properties with a Portland address that are outside official city limits and are under county control. The following table summarizes important metrics for Washington County:

The total sales volume dollar amount increased by over 13% thanks, in part, to a 27% increase in the total number of sales. The reason the sales volume dollar amount did not climb higher is due to smaller units selling on smaller lots. There were no distressed sales or new construction in 2024.
Clackamas County 2024 Stats
Clackamas County, due to being a large and mostly rural county, has the most activity for manufactured homes in the Portland Region. The following table summarizes important metrics for Clackamas County:

The Clackamas manufactured home sales volume dollar amount was down about 20% in 2024. This tracks the decrease in total sales (-22%). Average prices were slightly up, but so was the average total square footage of homes selling. The one-acre drop in average lot size does not appear to have had a substantial impact on average prices. There were two new construction units in 2024 and just one distressed sale.
Yamhill County 2024 Stats
Yamhill County is known for its wineries and other agricultural products. Due to its rural areas, Yamhill had the second highest number of manufactured home sales. The following table summarizes important metrics for Yamhill County:

The total sales volume dollar amount was flat year over year. There was little change in the number of homes sold. Average prices rose nearly 3% despite smaller units on smaller lots for 2024. This indicates manufactured homes had a stronger year overall compared to 2023. There was no new construction activity and only a couple of distressed sales in 2024.
Columbia County 2024 Stats
This county is 688 square miles but only has a population of approximately 54,000 people. Due to it mostly rural nature, Columbia County came in third for the total number of manufactured home sales. The following table summarizes important metrics for Columbia County:

Total sales volume dollar amount changed only 2.4% and there was almost no change in the size of the average manufactured home. Average prices rose 12% but that may be partially attributed to a nearly 61% increase in average lot size.
Hood River County 2024 Stats
Hood River is the second smallest county in Oregon by area at 533 square miles. The population is estimated to be about 24,000 people. With such a sparse population it is no surprise this county had little activity.

There was a 33% drop in the sales volume dollar amount, but that almost mirrors the 25% decline in the total number of sales. The average size of the units did not meaningfully change, but the average lot size dropped 21%, which likely contributed to the sharper decline of the sales volume dollar amount.
