มูลค่าที่ดินในการประเมินมูลค่าทรัพย์สินเพื่อที่อยู่อาศัย :กรณีศึกษา บริษัท จัสติส พร็อพเพอร์ตี้ แอนด์ แอพไพรซัล จำกัด / กฤษฎา เพ็ชรประยูร = Land value in asset valuations for housing : a case study of justice property and appraisal company limited / Krisada Petchprayoon
The general purpose of this study was to research into the land value in asset evaluations for housing in the Bangkok Metropolitan area. The specific purposes were to study such common predictors affecting the price per square wah of a piece of land. These include the demarcation of Bangkok, the development of land for housing, the distance from the main road to the housing areas, the shape of the land, the level of the land compared to the road running in front of the land and the public utilities in the areas. In addition, the study compared the land value per square wah between the land demarcated by the Bangkok Metropolitan area and the land developed for various types of housing. The study also investigated the relationship between the land value per plot and the building value. The samples were retail customers of the Government Housing Bank. Their pieces of land were appraised for housing by the Justice Property and Appraisal Company Limited from June 1, 2001 to May 31, 2002. Based on the disproportional stratified random sampling, the samples were chosen from the 964 customers. Taro Yamane's formula was used to calculate the size of the samples. The result was 282 customers. The aforementioned factors were used to analyze the data. The tools were the samples' records analyzed by frequency, percentage, mean, standard deviation, multiple regression analysis, one-way analysis of variance, independent samples test and Pearson product moment correlation coefficient. It was found that 1. The order of importance of factors affecting the land value per square wah was (1) the location (inner city was more important than urban fringe.), (2) the land developed by a real estate agent, (3) the land which was over 20 centimeters higher than the road running in front of it and (4) the land equipped with electricity, a water supply, a drainage system and street light. 2. The division of Bangkok into inner city, urban fringe and suburb could differentiate the land value. Moreover, the land developed by a real estate company cost more that that developed by the land owner. 3. According to asset evaluations for housing, the land value per plot was related to the building value. In other words, when the land value was high, the building value was high too. The results could be incorporated when the assets for housing was appraised or used to analyze the use of land for housing in line with the land value. Moreover, the statistical methods used in this study could be applied to the analysis of land value so that the actual land value could be obtained.
