proposed based on analyzing of previous literature Then the model is tested on a pilot test which is conducted of a small real estate professional group and another group of 15 respondents, and on a larger survey of 263 samples The study finds out a strong positive relationship between top two factors, including “living space”, “distance” and customers’ housing purchase decision The three weaker positive relationship factors are “feature”, “finance” and “environment” to housing decision makers It is also found that there is no difference in decision making of customers according to different demographics consisting of gender, age, marital status, monthly income and education level Key works: real estate, purchase factors, Vietnam iv TABLE OF CONTENTS ACKNOWLEGEMENTS ii ABSTRACT iii LIST

Economic CHAPTER INTRODUCTION 1.1 BACKGROUND As universal population levels continue to rise, the housing shortage in many developing countries has reached critical levels (Morel, 2001, p 1119) Real estate is one of the most important things to citizens, so “the house purchase decision of them can change their life” (Wells, 1993) The house purchase decisions are different from other business decisions due to “the innate, durable and long-term characteristics of real estate” It is a highly differentiated product with “each specific site unique and fixed in location” (Kinnard, 1968) In Vietnam, it is known as the third largest population in South East Asia and ranked the 14th largest in the world in terms of total population Its population estimated of 89 million in 2010 (GSO, 2011) The annual average growth population of Vietnam from 2000 to 2010 was approximately 1.03 million people per year or 1.2% annual growth Particularly, one of the top economic centers of Vietnam is Ho Chi Minh City which has around 7.2 million people as in April 2009, but its actual population is likely to be significantly higher because of unrecorded migration from rural areas The real estate market in Vietnam has significantly changed during from the 1990s to now and it might be seen as three times fever and declining prices in the last 20 years Up to the end of 2012, the large real estate outstanding loans and a big number of inventories created a serious crisis However, according to the Deputy Minister of Construction Nguyen Tran Nam, he emphasized that “people’s housing demand is very large and solvency is high, but the real estate market lacked of information” 1.2 RESEARCH PROBLEMS & RESEARCH QUESTIONS In general, the real estate in Vietnam has got many difficulties in making effort to satisfy customer demands According to incomplete statistics of the Ministry of Construction surveyed in 44 provinces up to August 30th, 2012, the country now had 16,469 unsold apartments, in which HCMC was 10,108 unsold apartments and total number of inventories of low buildings was 4,116, in which HCMC was 1,131 ones (Anh, 2012) Therefore, the Prime Minister stressed that the solution to rescue real estate market should be included in the Resolution of the Government The main reasons of the crisis were the real estate market supply did not meet customer demands, the investors lacked of exact information of customer and real estate market conditions “There are two main fields of customer research are how customers go about making decisions and how decisions should be made In addition, “creating true value for customer and customer notion focused approach” is confirmed (Edwards & Fasolo, 2001) It is found that “customer decision making is one of the most important areas of customer behavior and it requires gathering a lot of regarding information” (Bettman et al., 1998 & Simonson et al., 2001) There have been many published academic research about customer house purchase with variety of both developed and developing countries However, “the national and cultural characteristics play a very significant role in house purchase decision, that mean finding which is applied in specific context may not extend to another context” (Opoku & Abdul-Muhmin, 2010) The real estate in Vietnam has got specific characteristics to which connected customer demands closely In recent years, researchers, domestic and foreign companies attracted to real estate field in Vietnam with a number of research works However, there has been not enough research into the way customers making decision to buy real estate as well as which major factors have got relationship with customer decision Consequently, in the term of real estate purchase decision of customers, the research questions of the thesis are raised as two following questions: 51 Yếu tố Mức độ TT có quan trọng đến định mua nhà không? quan trọng 21 Lệ phí trước bạ mua nhà 22 Số lượng phòng
