Forecasting Model of Residential Rental Rates for Dormitories or Apartments in the Area Surrounding the Educational Institute: A Case Study of Thammasat University, Rangsit Campus
Main Article Content
Abstract
Migration to work or study in Pathum Thani province increases the demand for temporary accommodation. Tenants' decision to rent a room depends on various factors. This research aimed 1) to study physical factors affecting residential rental rates in the areas surrounding Thammasat University, Rangsit Campus, and 2) to construct a linear model for forecasting rental rates. The research model is a quantitative research using the theory of multiple regression analysis as a research conceptual framework. A studied area is a dormitory or apartment within a radius of 5 kilometers surrounding Thammasat University, Rangsit Campus. The samples in this research were the 400 entrepreneurs of a dormitory or apartment within a radius of 5 kilometers surrounding Thammasat University, Rangsit Campus, selected by convenient sampling. The research tool is a checklist. Data were analyzed by using multiple regression analysis by selecting variables with the stepwise method. The research results showed that 1) physical factors affecting residential rental rates in the areas surrounding Thammasat University, Rangsit Campus consist of 10 factors: fitness, room interior, security guard, usable area, free internet or wifi, convenience store, restaurant, beauty salon, elevator, and laundry and 2) The best rental rate forecasting model is Linear – Linear model which has a high percentage accuracy equal to 77.10% or only accounted for the error equal to 22.90%. It is the only form of forecasting equation that has a Durbin-Watson value which is between the Durbin-Watson value obtained by opening the table, indicating that the tolerances are independent of each other with the mean of residual value equal to 0.000 and the sum of square residual equal to 84.940. The equation for forecasting rental rate was LogY of the standard value of monthly rental rate equal 0.338 (standard value of fitness) + 0.274 (standard value of room interior) + 0.034 (standard value of security guard) + 0.214 (standard value of usable area) + 0.082 (standard value of free internet or wifi) - 0.205 (standard value of convenience store) + 0.160 (standard value of restaurant) - 0.111 (standard value of beauty salon) + 0.113 (standard value of elevator) + 0.078 (standard value laundry).
