Real estate market data

The stated rental prices are standard market ranges, stated as from and to values, or modal rents that relate to a property that is typical for the location. The rental prices provide information about the net rents and are given in euros per square meter and month. Extremes, both upwards and downwards, are not taken into account. The specified rents are approximate and provide an additional orientation within the specified range. A larger number of properties typical for the location are rented at this value. The market for new letting of existing space and new-build first-time occupants is shown. Existing rents from existing rental contracts are not taken into account. The values ​​reflect the financial statements of the previous year and are based on a survey of real estate experts as well as the expert committees and business development agencies in the FrankfurtRheinMain metropolitan region. If the data basis is insufficient, rental prices or rent ranges are not given for the respective segment and marked with k. A. (not specified).

Office space

An office space is the area that is primarily used for working at the desk. The area can be in pure office properties or in mixed-use buildings. No distinction is made between different office space standards. In the regional centers of Aschaffenburg, Darmstadt, Gießen, Hanau, Mainz and Offenbach am Main, the office space is divided into preferred and other locations. Preferred locations are characterized by the presence of good transport links, sufficient parking space, as well as shops for daily needs and a gastronomic offer. The regional centers of Frankfurt am Main and Wiesbaden are subdivided into individual districts.

Retail space

Standard areas of up to around 120 square meters are considered retail areas. Areas in shopping centers are not taken into account. The catering areas include properties that have the necessary technical systems (including air systems, refrigeration and cooling systems, guest toilets). Gastronomy areas are exclusively subdivided into primary locations, the retail areas into primary and secondary locations.

Primary location: highest pedestrian frequency, central shopping opportunities in the area, extensive branch mix (hotspot location). Primary locations have the highest density of shops, including magnet shops and often branches. Good transport links and parking opportunities.

Secondary location: solid pedestrian frequency, shopping opportunities for daily needs, restricted branch mix, less crowded shops compared to primary locations. Not optimal transport connections or limited parking opportunities.

Logistics and production areas

For the logistics and production area segment, a standard area with an average equipment – based on the following criteria – is assumed: high voltage connection, ceiling height of at least five meters, heatable, ramp gates or driveway at ground level. The stated prices exclude larger office and social areas (approx. > ten percent of the total area). The rental price can vary significantly up or down if criteria are above or below average.

Statistical data

Labour market

The number of employees subject to social insurance at the place of work indicates the number of employees working in the respective city or district. Employees subject to social insurance at the place of residence are those employees that are employed at the place they live.

The unemployment rate, based on all civilian labour force, measures the percentage of registered unemployed in relation to the total number of the civilian labor force. The civilian labour force is the sum of the dependent civilian labour force plus self-employed persons and family workers.

Population and area

Population density indicates the ratio between the number of inhabitants and the land area of a given territory. Population includes all residents regardless of registration status or citizenship with the exception of refugees who are not permanent residents. Land area is the total area of a state. Population density is expressed in inhabitants per square kilometre.

Purchasing Power

Purchasing power refers to the disposable income of the population in a region a region's population (income excluding taxes and social security contributions, including transfer payments received). The purchasing power index expresses how high the purchasing power of a specific region is compared to the selected average. The standard value for the average is always 100. A value above 100 means that the population in the area has above-average purchasing power. The retail purchasing powerindex only considers the income components available for retail spending (including Internet and mail-order business).


Inbound commuters are employees who do not live at their place of work. Outbound commuters are employees who do not work at their place of residence. Commuter balance is the difference between inbound and outbound commuters. If the balance is positive, the number of inbound commuters predominates. If, on the other hand, it is negative, the number of outbound commuters is higher.

Tax assessment rates

Taxassessment rate is the percentage rate set by the municipality for the respective calendar year, which is applied to the measured amounts of the real taxes (trade tax, property tax A and B). Land tax is levied on land, including buildings. Property tax B (building) is land with residential buildings.

Economic data

Gross value added (GVA) results from the total value of goods and services produced in the production process (production value), reduced by the value of intermediate consumption, the costs incurred for goods or services in the production process, e.g. for raw materials and supplies, intermediate and semi-finished products, repair costs, interest payments, commissions, rents, leases and fees.

Centrality ratio

Retail centrality data reveal the retail drawing power of a given location. It indicates the extent to which the local retail trade is able to attract supra-regional customers. The retail sales made in a given region are compared with the retail-relevant purchasing power. A value above 100 indicates that more purchasing power flows from the surrounding area into the given region than vice versa.

The centrality level indicates the spatial planning hierarchy level of the respective municipality.
