Relevant for you
Do you let properties that aren't your primary residence?
Anyone operating rental properties outside their own primary residence in Berlin — one property or several — faces concentrated 2026 regulations on rent control, the 5 % furniture-surcharge cap, refined fixed-term clauses, and new notification duties. The impact differs substantially by rental type.
Three constellations are typical in practice: standard long-term unbefristet rental (one property or several), furnished mid-term rental (befristet, 2–12 months), and portfolio monitoring of 3–15 properties across different rental types. Each falls under different rules — and not every rule applies to every constellation.
MietSense organises these regulations per property in structured form: rent-index reference value, furnishing requirements, fixed-term framework, each with source citations. The L2 dashboard, available later, is designed for portfolio operators.
Which constellation matches your situation?
Within this group, several typical constellations exist, each with its own legal landscape. Pick the one that most closely matches your situation.
Long-term rental
You let one or more apartments (that aren't your primary residence) as standard unbefristet long-term lets. Rent control, furniture-surcharge rules, and fixed-term regulations all apply — regardless of property count.
Read more →Mid-term rental
You operate furnished mid-term rentals (typically 2–12 months) of properties you don't live in yourself. §549 (2) BGB and §575 BGB on fixed-term rentals are central here.
Read more →Portfolio monitoring
You manage a portfolio of 3–15 properties in mid-term or shared-living rental. This profile typically routes to the L2 subscription rather than the one-off report.
