Germany's residential rental market presents a stark paradox that reveals the country's deepest housing tensions. While official statistics show the average German pays just €7.28 per sqm in rent, new tenants face a brutal reality where asking rents have surged 62% since 2017. This growing divide between existing and new rental contracts is creating two distinct housing markets—one affordable for those who stay put, another increasingly unaffordable for anyone who needs to move.
The contrast couldn't be sharper. On online platform Kleinanzeigen, a young Munich family offers a €1,000 finder's fee for a three-room apartment, competing against hundreds of other searchers. Meanwhile, 40 kilometers from Dortmund in Marl, landlords advertise three-room flats for €440 monthly rent with the first month free. These aren't different countries—they're different Germanys, shaped by when you last signed a lease and where you need to live.
The rent divide stems from Germany's tenant protection laws, which keep existing rents relatively stable while new contracts face market forces. Federal Statistical Office census data from 2022 shows 80% of apartment units were rented for under €750 excluding utilities (Kaltmiete). Many long-term tenants enjoy these lower rents, with some paying as little as €550 for 100 sqm apartments. But anyone entering the market today faces dramatically different conditions.
"High rents for new contracts are problematic for several reasons," notes real estate consultancy JLL. "They mean that young families are stuck in apartments that are far too small, while many single people live in apartments that are too large." The result is market inefficiency where space allocation no longer matches household needs.
Despite the divide, rental growth is now showing signs of moderation after years of rapid increases. The recent GREIX Rental Price Index from the Kiel Institute shows asking rents rose just 0.7% in Q2 2025 compared to the previous quarter—below the overall inflation rate. When adjusted for inflation, asking rents actually fell 0.2% in real terms.
"Compared to 2024 and the beginning of 2025, when rental prices surged strongly, the current price trend is much more moderate," explains Jonas Zdrzalek, real estate market expert at the Kiel Institute. Annual growth has cooled to 3.4% nominally and 1.3% when inflation-adjusted, down from much higher rates in 2024.
Yet this moderation masks continued market intensity. JLL reports asking rents in major metropolitan areas still rose 4.9% year-on-year, with Hamburg posting 13.7% growth. More significantly, existing housing stock rents are now rising faster than new construction rents—6.8% versus 3.3% according to JLL. This reverses the previous pattern and suggests the rent divide may be narrowing as existing tenants face larger increases.
Market demand remains extraordinarily strong despite high prices. Apartment listings now stay online for an average of just 23 days, down from 34 days in 2015. The speed is even more dramatic in major cities: in Berlin, 25% of apartments disappear from the market within two days of listing.
"This shows that the demand for housing is very high. This is particularly challenging in major cities, where securing a suitable apartment can be difficult," Zdrzalek notes. The rapid absorption rate indicates landlords retain significant pricing power despite economic uncertainty.
The rent divide plays out differently across Germany's fragmented market. Munich commands the highest asking rents at €22.82 per sqm according to GREIX data, more than double Leipzig's €10.10 per sqm. Frankfurt follows at €17.32 per sqm, while Berlin, Stuttgart, Hamburg, and Cologne cluster around €15-16 per sqm. Even Düsseldorf, traditionally expensive, posts relatively moderate €14.25 per sqm.
These price gaps reflect varying local dynamics. Some markets like Hamburg saw strong 1.3% quarterly growth, while others like Frankfurt remained flat at -0.2%. Rural areas continue catching up with strong growth - village rents have risen 50% since 2017 according to JLL analysis, though from much lower bases.
Single-person households face particularly acute pressure within the rent divide. Federal Statistical Office analysis shows people living alone pay 7.7% more per sqm in large cities than multi-person households. Singles now comprise 52% of large city households, up from 37% in 2011, but small apartment supply has grown just 5.5% over the same period.
The mismatch is stark: single-person households increased by 25% between 2011 and 2022 to 17.4 million, while apartments under 60 sqm rose only from 9.5 million to 10 million. When new small apartments are built, they're often serviced apartments charging €20+ per sqm, far above what average earners can afford.
Construction completions fell to 252,000 homes in 2024, down 17% from previous years, with 2025 expected to drop further to around 220,000 units. This supply shortage perpetuates the rent divide by limiting options for new tenants while protecting existing tenants from displacement.
The rent divide is approaching sustainability limits even as growth moderates. Property consultancy bulwiengesa forecasts "rent increases skyrocketing by at least three percent, and in some large cities we are seeing five percent and more," according to André Adami, Head of Residential North/East. Many renters already spend well above the recommended 30% of income on housing.
Some regions are hitting affordability ceilings. "Some areas are reaching the limits of affordability," JLL's Sören Gröbel observes. "People can no longer afford to live there and are unwilling to do so. Many landlords are likely to recognise this." This suggests the rent divide may eventually constrain further increases as demand reaches breaking points.
For institutional investors, the divide creates both opportunities and risks. Existing rental stock generates stable, index-linked returns from long-term tenants, while new lettings command premium rates but face higher vacancy risks and tenant turnover. The rapid re-letting speeds indicate strong underlying demand, but affordability constraints could limit future growth.
Policy responses remain limited. Zdrzalek warns that even successful housing programs "will still take time to materialize" given high demand levels. The rent brake (Mietpreisbremse) protects existing tenants but may inadvertently worsen the divide by discouraging new supply and encouraging landlords to maximize asking rents for vacant units.
The great German rent divide reflects deeper structural tensions between tenant protection and housing supply. As existing tenants enjoy relative stability and new renters face market pricing, the gap between housing haves and have-nots continues widening. Without significant supply increases or policy reforms, this two-tier market seems likely to persist—offering stable returns for patient capital but increasingly challenging social and economic consequences for German society.
