Buying a Bostadsrätt flat incurs 0% lagfart stamp duty (lagfart at 1.5% applies only to freehold houses/land). The buyer acquires a share in the Bostadsrättsförening (BRF) granting permanent right of occupancy.
Due diligence centres on the BRF annual report (årsredovisning), evaluating association debt per square metre (belåningsgrad), upcoming interest renewals, and planned major pipe renovations (stambyte).
