Dwelling Age, Redevelopment, and Housing Prices: The Case of Apartment Complexes in Seoul

Abstract

The aging of a housing structure not only leads to depreciation but also increases the possibility of redevelopment. If redevelopment accompanies an increase in structural density in order to accommodate the increased demand for housing, it provides large capital gains to the existing owners. In this case, expectations of redevelopment in the near future and the eventual announcement of redevelopment plans can have a strong positive impact on the current price of housing. We test this hypothesis using a hedonic pricing model designed to decompose the age effects into depreciation effect and redevelopment effect. Based on 3,474 observations on apartments in Seoul in 2001, estimation results confirm our hypothesis. While the depreciation effect dominates the redevelopment effect until 15 to 19 years of age, depending on the specification, the redevelopment effect eventually dominates the depreciation effect thereafter, causing the apartment price to increase. At 27 years of age, the apartment price decreases by as much as 45∼53 percent of the initial value, due to depreciation. However, the redevelopment effect increases the price by as much as 28∼32 percent, driving the price up to 76∼87 percent of the original value.

Depreciation of housing capital, maintenance, and house price inflation: Estimates from a repeat sales model

“…Shilling et al [20], Lee et al [14]). Accordingly, for the repeat sales Model, we specify a non-linear depreciation function that avoids the perfect collinearity issue noted by Bailey, Muth and Nourse [1].…”

“…structural attributes of the home as instruments. 14 In the empirical work that follows, we estimate both an OLS and a 3SLS version of the Inflation Model.…”

“…14 In the empirical work to follow, we use the age of the home at the initial sale date, number of rooms, bedrooms, bathrooms, central city versus other location, condominium status, and whether the home is single family detached. Each of these variables is also interacted with house age.…”

The impact of construction quality on house prices

“…We also include the number of quarters between the two sales, i, which captures age-related depreciation, as well as its square term to reflect the fact that houses depreciate at a non-linear rate (see Shilling et al, 1991;Lee et al, 2005). The binary variable PRIME is defined as units that are located in the prime residential district.…”

Impacto de las grandes actuaciones urbanísticas y de proyectos de transporte en el Área Metropolitana de Barcelona

“…En términos de planificación, se analizan los efectos de diversidad de actividades normadas, de diversidad racial (Song y Knaap, 2004) y de calidad de la educación impartida por los establecimientos (Simons et al, 1998 (Macpherson y Norman, 2006;De Sousa et al, 2009). Una aportación novedosa respecto de la edad de la construcción la plantean Lee et al (2005). La investigación concluye que el aumento de la antigüedad de la construcción aumenta la posibilidad de una renovación, aumentando así la expectativa de valor inmobiliario en Seúl (año 2001).…”
