The datasets below pertaining to Private Property in Singapore are extracted from https://beta.data.gov.sg, Singapore's national open data collection portal.
The prices in 2009-Q1 are used as the base reference price of the index. The indices are compiled based on a Stratified Hedonic Regression method. The value of properties transacted in the past 5 quarters are used as weights. The weights are revised every 3 years. The latest revision was in 2015-Q1.
The residential rental index covers only private residential properties. It does not cover HDB flats.
The rental index is computed from information obtained in returns filed with the Inland Revenue Authority of Singapore (IRAS). When a property is let out, the property owner has to inform IRAS the details of the tenancy agreement. Besides an overall rental index for private residential properties, sub-indices for landed and non-landed properties are also compiled
