- Deposit (Kaution): legally capped at 3 months' cold rent
- Rent brake (Mietpreisbremse) in tight markets: extended to 2029
- Buying: no restrictions on foreign buyers; prices +3.2% in 2025 (Destatis) — first rise since 2022
- Transfer tax (Grunderwerbsteuer): 3.5% to 6.5% depending on the state

What rents actually cost — a large-sample listings index, not one-off ads
The GREIX index (Kiel Institute) is built from asking rents pooled across multiple listing platforms and adjusted with a hedonic method to strip out mix effects — a far larger, more consistent sample than eyeballing a few ads, though it is not signed-lease (transaction) data. The Kiel Institute separately publishes a transaction-price comparison; where the two diverge, the underlying report is the more precise source. Q3 2025 figures for new lets, per square metre cold rent:
| City | New-lease rent (Q3 2025) |
| Munich | €22.96/m² |
| Frankfurt | €17.55/m² |
| Stuttgart | €16.11/m² |
| Berlin | €15.82/m² |
| Hamburg | €15.62/m² |
| Cologne | €15.21/m² |
| Leipzig | €10.22/m² (Q4 2025) |
| Dresden | €9.89/m² (Q2 2025) |
Sitting tenants pay far less: the national average for existing tenancies is around €9.25/m² (market aggregate, early 2026 — indicative). That gap is why Germans don't move often, and why the newcomer pays the top of the market. An 80m² apartment in Berlin at new-let rates: roughly €1,265/month cold, before utilities.
The vocabulary that decides your budget
| Term | What it means for you |
| Kaltmiete | "Cold rent" — the base rent. This is the number in listings and in the table above. |
| Warmmiete | Cold rent plus building costs and usually heating. Typically 20–30% above cold rent. Budget on this number, not Kaltmiete. |
| Kaution | Deposit — capped by law at 3 months' cold rent, payable in three instalments if you ask. |
| Mietspiegel | The official local reference-rent index. It caps what landlords can charge and how fast rents can rise on existing leases. |
| Mietpreisbremse | The "rent brake": in designated tight markets, new-lease rents may not exceed the Mietspiegel reference by more than 10% (with exceptions, e.g. new builds). Extended to 2029. |
| Wohnungsgeberbestätigung | Landlord's confirmation form — you need it for Anmeldung (address registration), which everything else hangs off. |
Expect unfurnished to mean bare. German rentals routinely come without light fittings and sometimes without a kitchen. Furnished and temporary listings — a fast-growing share of the big-city market — dodge some rent rules and cost accordingly. For a permanent move, an unfurnished standard lease is almost always the better deal.
Buying: open door, heavy closing costs
There are no restrictions on foreign buyers — no residency requirement, no extra stamp duty for non-residents, nothing. Residential prices rose 3.2% in 2025, the first annual increase since 2022 (Destatis). What catches North Americans out is the transaction cost stack:
- Grunderwerbsteuer (transfer tax): 3.5% in Bavaria (the lowest rate nationally; Saxony raised its rate to 5.5% in 2023), up to 6.5% in North Rhine-Westphalia, Brandenburg, Saarland and Schleswig-Holstein — set by each state.
- Notary and land registry: roughly 2%. The notary is mandatory and neutral — no title insurance industry, the land registry (Grundbuch) is definitive.
- Agent commission: split between buyer and seller by law; the buyer's share is often around 3.57% including VAT.
- All-in: plan on 7–12% on top of the purchase price, unrecoverable. Buying only makes sense if you're staying — the break-even against renting is measured in years.
