Survey of Market Absorption of Apartments (SOMA)

About the SOMA Survey - Second Quarter 2000

The Survey of Market Absorption (SOMA) measures how soon privately financed, nonsubsidized, unfurnished units in buildings with five or more units are rented or sold (absorbed) after completion. In addition, the Survey collects data on characteristics of the units such as number of bedrooms, asking rent, and asking price.

All statistics from the SOMA are limited to apartments in newly constructed buildings with five units or more. Absorption rates are based on the first time an apartment is rented after completion or the first time a condominium or cooperative apartment is sold after completion. If apartments initially intended to be sold as condominium or cooperative units are, instead, offered by the builder or building owner for rent they are counted as rental apartments. Units categorized as federally subsidized are those built under the following programs of the Department of Housing and Urban Development (Section 8, Low Income Housing Assistance, and Section 202, Citizens Housing Direct Loans) and all units in buildings containing apartments in the Federal Housing Administration (FHA) rent supplement program. The data on privately financed units include privately owned housing subsidized by state and local governments. Units categorized as not in the scope of the survey include time-sharing units, continuing care retirement units, and turnkey units (privately built for and sold to local public housing authorities after completion).

Tables 1 through 4 and Table 9 provide information about privately financed, nonsubsidized, unfurnished, rental apartments. Table 5 provides information about privately financed, nonsubsidized, condominium and cooperative apartments, while Tables 6 through 8 and Table 10 provide information about condominium apartments only. Table 11 is a summary table which includes all newly constructed apartments in buildings with five units or more.
