ASSEMBLAGE
As Applied to Manufactured Housing
In order to arrive at a market value opinion for a property under analysis, sales data used for the analysis
must also meet the definition of market value. This means a sale comparable is a property (a single
property) that has been exposed to competitive and open market conditions requisite to a fair sale:
(1) buyer and seller are typically motivated;
(2) both parties are well informed;
(3) a reasonable time is allowed for exposure in the open market;
(4) payment is in terms of U.S. dollars; and
(5) the price represents the normal consideration for the property sold unaffected by special or
creative financing or sales concessions granted by anyone associated with the sale.
USPAP SR 1-4(e) states: “An appraiser must analyze the effect on value, if any, of the assemblage of the
various estates or component parts of a property and refrain from valuing the whole solely by adding
together the individual values of the various estates of component parts.”
Market Value Definition as applied to comparable sales for the analysis and appraisal of new manufactured
homes:
• If a person were to buy a site, put a new manufactured home on a permanent foundation on the site,
connect all the utilities, provide adequate access (driveway, walks, etc.), expose it to the open market,
and negotiate a sale of the property; this sale could be used as a sales comparable for a new
manufactured home.
• If, however, a site was purchased from one party, and a manufactured home from another, and site
development, permanent foundation, etc. from another, this could not be used. Costs gathered were
from different units of production, and may or may not represent the value of the whole and must not
be used as a comparable sale. This is an example of an assemblage, not the sale of a single property
offered as one unit on the open market.
We found an excellent article on the subject of assemblage written by Jo Ann Meyer Stratton, IFA, SRA.
A portion of the article is reprinted below with permission of the National Association of Independent Fee
Appraisers.
“Typically, arms length transactions of properties exposed to the market of manufactured homes
of similar quality to your subject manufactured home are the most representative of comparables.
Manufactured homes of very good or excellent quality with similar "site built" installation, exterior
and interior amenities might compete equally with a site built home, depending on the neighborhood.
An appraiser would be required to determine from market research for the subject area if
there would be a negative "trailer" reaction to the above average quality and appeal of the
manufactured home. Knowledge of the subject market, availability and appeal of all types of
homes in that market is extremely important.
“When the situation occurs of a buyer purchasing a lot from an individual, purchases a manufactured
or modular home from a dealer, hires contractors to prepare the site, install utilities, and install
the home, that is known as a land/home package. This is the same process as a site built home for
an individual on their lot or a lot they purchase. The total package has not been exposed to the
market as a single entity. Later, an appraisal is ordered for another land/home package and the
appraiser is asked to develop an opinion of market value, with the intended use of the results to
identify collateral risk for a mortgage. The sum total of another land/home package would not be
a market sale that could be used as a comparable for any type of residence, whether it is a site built
home, manufactured home, modular home, panelized home, etc. That land/home package could
be an indication of the cost approach to value but would not be consistent with the market
approach because the costs of the improvements are not based on their actual contribution to the
site.”
