Frankfurt condominium prices rose 2.4% in Q3 2026

Condominium prices in Frankfurt am Main rose 2.4 percent in the third quarter of 2026, both compared with the second quarter and against the same period a year earlier, according to figures highlighted by Frankfurt-based brokerage Marc Haerter Immobilien. The increase, drawn from the GREIX Purchase Price Index published November 5, came even as the city's official appraisal committee reported a roughly 15 percent decline in the number of condominiums sold during the first half of the year. Higher prices and fewer transactions, the firm notes, are not mutually exclusive.

Index Shows Frankfurt Outpacing the Nation

The 2.4 percent quarterly and annual increase in Frankfurt condominium prices compares favorably with the broader national picture. The nationwide GREIX Housing Index showed a slight year-over-year decline of 0.2 percent over the same period, meaning Frankfurt's local market moved against the national grain in the third quarter.

The GREIX index is built from completed, notarized sales recorded in purchase price databases maintained by local appraisal committees, rather than from asking prices or listings. Statistical adjustments account for differences between properties sold — including location, size and condition — so the published figure reflects an adjusted market trend rather than the price movement of any single apartment. The changes are also nominal, meaning they are not adjusted for inflation.

Marc Haerter, a real estate economist (EIA) who owns and runs Marc Haerter Immobilien, specializes in appraising and selling residential property across Frankfurt and the neighboring Taunus region. The firm's reading of the latest data frames the quarter as a positive signal for condominium values in the city, while cautioning that it is too early to call it a sustained trend.

Transaction Volume Tells a Different Story

Separate figures from the Frankfurt Appraisal Committee paint a more cautious picture of market activity. In the first half of 2026, 1,354 condominiums changed hands in the city, down from 1,589 in the same period of 2025 — a decline of about 15 percent. The firm notes that these half-year sales figures cover a different time window than the quarterly price index and should not be compared directly to it.

Within that half-year data, results diverged sharply by building age. Newly built condominiums sold for an average of roughly 8,200 euros per square meter, just under 7 percent higher than a year earlier. Apartments built in 1991 or later, excluding new construction, carried a median price of 6,670 euros per square meter — about 6 percent lower than the prior year. The firm attributes that drop largely to a compositional shift: proportionally fewer very new apartments were sold within that category compared with the year before, which pulled the median down without necessarily reflecting a loss in value for comparable units.

That distinction between index movements and simple averages matters for anyone pricing an individual apartment. A market index captures a general trend, while a price-per-square-meter average blends many different sales together. For a specific unit, factors such as floor plan, level of modernization, floor level, outdoor space and the condition of shared building areas can all move the final price well away from any headline figure — and listing prices, which largely reflect what sellers are asking, differ from the notarized contract prices that feed into the official index.

Price indices built from completed sales, like GREIX, are widely used across German cities precisely because they strip out the noise created by shifting property mixes — a newly built luxury tower sold one quarter and a stock of older walk-ups sold the next can otherwise distort a simple average. That methodological care is part of why composition effects, such as the one seen in Frankfurt's 1991-and-later segment, can produce a falling average price even when comparable apartments are holding or gaining value. For buyers, sellers and agents trying to read a market with both rising prices and falling transaction counts, the gap between index and average is often the first thing worth checking.

No complete analysis is yet available for the fourth quarter of 2026, which was still underway at the time of the report. Whether Frankfurt's condominium market sustains this price momentum, or whether falling transaction volumes eventually weigh on values, will become clearer only in the quarters ahead. For now, the data point to a city market moving in a different direction than Germany as a whole.
