This paper examines the search behavior of a sample of Portuguese and Canadianborn homebuyers in suburban Toronto, Canada. Attention is focused on the extent to which Portuguese homebuyers rely upon real estate agents from the same ethnic background and how this source can influence the homebuyer's housing search and ultimate choice of a residence. Data were obtained from a questionnaire survey that was administered to a sample of 110 Portuguese and 90 Canadian-born recent homebuyers in the city of Mississauga, a western suburb of Toronto. All were nonresidents of Mississauga at the time of purchasing the house. The evidence indicates that Portuguese homebuyers differ significantly from the Canadian-born in their housing search by relying more extensively on ethnic sources of information, particularly real estate agents from the same ethnic background. However, almost equal numbers of Portuguese purchased houses in Portuguese and non-Portuguese neighborhoods in Mississauga. In this respect, the evidence suggests that Portuguese realtors play a more limited role in reinforcing existing spatial patterns of Portuguese settlement in Mississauga.Many homebuyers purchase houses infrequently and lack experience and knowledge about the homebuying process. As a result, the task of looking for and gathering information about residential vacancies can be stressful, costly, and time-consuming, especially in complex and heterogeneous metropolitan housing markets. The gathering of information about housing vacancies, and the search itself, also can be more complex and difficult for certain groups. Visible minorities and recent immigrants, for example, may be in a disad-497 498 TEIXEIRA AND MURDIE vantaged position when searching for and evaluating alternatives because of discrimination, language barriers, and lack of familiarity with the intricacies of local housing markets. Consequently, home seekers often look for information and advice from experts or specialists to help identify and evaluate housing alternatives.Potential homebuyers can obtain information about housing vacancies from a wide variety of sources. These range from market sources such as newspapers and real estate agents to more-specialized community-oriented sources such as friends, relatives, and real estate agents from the same ethnic background (e.g., Brown and Moore, 1970;Barrett, 1973;Rossi, 1980;Margulis, 1988;Sarre et al, 1989). The amount, quality, and biases of housing information provided by these sources can vary from one source to another and may ultimately determine the efficiency of the search strategy and the final outcome of the relocation process. Thus, differentials in search behavior, including access to different types of racially and ethnically biased information, can be a key factor in maintaining racial and ethnic segregation in housing.Of the sources noted above, real estate agents are one of the most important channels of information in the housing-search process. The study of the influence of real estate agents on household relocation...
