The Swedish residential mortgage lender SBAB (www.sbab.se) launched a residential information service (named "Storstadsguiden") this Friday. It's a free service that shows medium price per square meter for apartments in Stockholm, Göteborg and Malmö.
Each town is divided in 15 - 30 sub markets. Each sub markets has a value based on actual transactions provided by Ljungqvist Information, which also runs the comparable sales service Ljungqvist (previously named treF).
The pressrelease is found here (in Swedish).
