What is the difference between selveier and borettslag in Norway in 2026?

With a selveierleilighet or eierseksjon you own your unit and co-own common parts through a sameie. Title registers through Kartverket. Used purchases usually trigger dokumentavgift of 2.5% of the purchase price; new-build calculations can differ when the land component is treated separately: Property purchase costs.

With a borettslag you buy an andelsrett (share) that gives exclusive use of a named flat. The cooperative owns the building. Part of what residents effectively carry is often fellesgjeld. Monthly felleskostnader commonly service that debt plus operations. You typically avoid the 2.5% dokumentavgift on the share transfer, which can matter for shorter holding periods.

Borettslag bylaws and husordensregler often restrict pets, renovations, and how quickly you may sublet. Existing members may hold forkjøpsrett (pre-emption) after a winning bid. Sameie rules exist too, yet many buyers find cooperative rental limits stricter: Can foreigners buy property.

Banks look at total price including your share of fellesgjeld when they set equity for borettslag: Foreigner mortgage. A low asking price with high shared debt is not a bargain. Ask for annual accounts and planned fee steps before you bid in Oslo or Bergen.
