Sammanfattning: Location-price data of undeveloped single-family properties are often limited and usually covers only recently urbanized areas in the outskirts of cities. Location-price data of developed single-family properties is also difficult to use for undeveloped single-family properties because the value ratio between land, buildings and facilities is hard to determine. An inadequate location-price data of undeveloped single-family properties leads to valuation uncertainty for a number of uses, such as property tax assessment and land encroachment. Sales of developed single-family properties where the purchaser demolish the old house in order to build a new house are categorized as a purchase of a developed single-family property, because of the property tax code. These transactions often occur in existing urbanized areas and are similar to sales of undeveloped single-family properties. The purpose of the project is therefore to develop a method to identify transactions where the buyer demolishes the old house in order to build a new house. Then compare these transactions with sales of undeveloped single-family properties to determine if they can form a joint location-price data for the undeveloped single-family properties. We conclude that “demolition-construction” purchases can be used to complement the existing location-price data for undeveloped single-family properties. These transactions can be very useful in areas where the existing location-price data of undeveloped single-family properties do not include the correct location factor.
