CoStar Group Inc. acquired U.K.-based online commercial property platform Realla Ltd. for an undisclosed price.

The Washington, D.C.-based commercial real estate data provider said Realla's expertise in capturing listings data in other European markets fits its strategy to expand in pan-European markets.

CoStar plans to double or triple investment into Realla and expand its footprint into continental Europe, Financial Times (London) reported, citing CoStar CEO Andrew Florance.
