Retta

What Retta does

Retta Isännöinti Oy is Finland's largest property management company, serving approximately 6,000 housing companies (taloyhtiöt) and managing roughly 150,000 residential homes across the country. Founded in 1970 and previously part of the Realia Group, Retta was acquired by Sweden-based international property management group Odevo in August 2024 and now operates as a sister company to Kontu under Odevo, with PE backing from Altor. The company provides comprehensive property management services including financial administration, technical management, statutory compliance, renovation oversight, and board support for apartment and property joint-stock companies of all sizes, through a nationwide network of local offices spanning Helsinki, Tampere, Kuopio, Siilinjärvi, Vaasa, Oulu, Turku, Lappeenranta, Hämeenlinna, Mikkeli, Kuusamo, Porvoo, Huittinen, Kemi, and Kerava.

The company's service portfolio is organized around three branded subscription tiers — RettaVakaa (comprehensive planned management at a fixed monthly price), RettaJousto (scalable service adjusted to housing company needs), and RettaHelppi (light-touch support for smaller housing companies needing help primarily with financial administration and statutory tasks). These services are underpinned by OmaRetta, a proprietary 24/7 digital self-service portal where board members monitor billing to transaction level, residents track maintenance requests in real time, and stakeholders manage communications. Retta's customer acquisition is sales-led, combining direct enterprise field sales for large housing company portfolios (suurasiakkaat) with website-driven quote requests and free assessment visits (kartoituskäynti) for mid-market and small housing companies.

Retta generates recurring revenue through monthly subscription management fees charged to housing companies, with quote-based pricing tailored to scope. The company has executed an aggressive consolidation strategy, completing more than 20 acquisitions of regional Finnish property management firms since 2019 (including Karjalan Tili- ja Isännöintikeskus, Aktiiva Oy, Buma-Team, Kantakaupungin Isännöinti, Tampereen KV-Isännöinti, Isännöinti Mannila, Abakus Oy, Hacklin Oy, Lillolle Ab, and Hyvinkään Isännöinti), integrating their books of business under the Retta brand while retaining local expertise and customer relationships.
