Analysis of housing prices in Petaling district, Malaysia using functional relationship model

Abstract

Purpose The purpose of this paper is to analyse and predict the housing prices in Petaling district, Malaysia and its six sub-regions with a set of housing attributes using functional relationship model. Design/methodology/approach A new multiple unreplicated linear functional relationship model with both the response and explanatory variables are subject to errors is proposed. A total of 41,750 housing transacted records from November 2008 to February 2016 were used in this study. These data were divided into 70% training and 30% testing sets for each of the selected sub-regions. Individual housing price was regressed on nine housing attributes. Findings The results showed the proposed model has better fitting ability and prediction accuracy as compared to the hedonic model or multiple linear regression. The proposed model achieved at least 20% and 40% of predictions that have less than 5% and 10% deviations from the actual transacted housing prices, respectively. House buyers in these sub-regions showed similar preferences on most of the housing attributes, except for residents in Shah Alam who preferred to stay far away from shopping malls, and leasehold houses in Sri Kembangan are more valuable. From the h-nearest houses indicator, it is concluded that the housing market in Sungai Buloh is the most volatile in Petaling District. Research limitations/implications As the data used are the actual housing transaction records in Petaling District, it represents only a segment of Malaysian urban population. The result will not be generalized to the entire Malaysian population. Practical implications This study is expected to provide insights to policymakers, property developers and investors to understand the volatility of the housing market and the influence of determinants in different sub-regions. The potential house buyers could also use the model to determine if a house is overpriced. Originality/value This study introduces measurement errors into the housing attributes to provide a more reliable analysis tool for the housing market. This study is the first housing research in Malaysia that used a large number of actual housing transaction records. Previous studies relied on small survey samples.

Purchasing Decision of Property Buyers: The Housing Quality, Financial Capabilities, and Government Policies Studies

“…It is a vital factor to determine how much to pay back with having a property or house. According to Chang et al (2019), at the time when interest rates decline, it is very tempting to purchase a house. This is provided if the rates are reduced due to the weakened economic growth with other factors remaining, the prices of the house would not incline.…”

House Price Prediction using a Machine Learning Model: A Survey of Literature

“…The model selection to be used to predict house price is quite critical as varieties of models are available. One of the most commonly utilized models in this research field is Regression Analysis which is used in many studies, including [3,10,21]. Another common model for house price predictions is the Support Vector Regression (SVR) [7,22,23].…”

“…Meanwhile, consumers have the capital to make a large investment, and the construction industry is vibrant or otherwise can be seen through the high level of house supply or demand in a country. Nevertheless, house has become unaffordable as there is a significant price expansion in the housing market sector in many countries [2].…”

“…Unfortunately, ML is relatively limited and very far from being used in real estate applications mainly in the Malaysian sense. Evaluation of property prices and values is extremely critical for the real estate sector, the stock market, the economics and tax sector, as well as the scale of buyers' and sellers' wallets [9]. Although researchers are relatively aware of the existing current prediction model, consideration should be given to the current methodologies constrained by the scope of data of the current system in the real estate industry.…”

“…As various factors such as location and property demand could affect house prices, most parties involved including buyers and investors, housebuilders, and real estate market may want to know the exact attributes or the main factors affecting house prices to assist investors in making decision and to facilitate house builders in setting house prices [2], [10], [11]. Nevertheless, other characteristics including distance from local facilities and the physicality of a house might be overlooked.…”
