Rental value

The rental value refers to the rent that can be obtained for a property under current market conditions. It forms the basis for the income approach in real estate valuation and plays a decisive role in determining the market value of income-generating properties. A distinction is made between the actual rental value (rent actually paid) and the target or market value (the amount that can typically be obtained on the market).

The rental value is therefore relevant not only for appraisers and banks, but for every owner who wishes to sell, mortgage, or profitably manage their property. An incorrectly estimated rental value leads either to loss of income (if set too low) or to vacancies and legal risks (if the market value is exceeded when re-leasing).

Rental Value as a Basis for Valuation

In the income approach, a property’s annual gross income is derived from the sustainable rental value. Appraisers and banks always use the market-standard rental value-not short-term peak rents or outdated existing rents. The higher the assessable rental value, the greater the calculated income value and, as a rule, the achievable sales price. For owners of multi-family homes and investment properties, the rental value is therefore one of the most important indicators.

The difference between the actual rental value and the market value is often significant for existing properties. In Nuremberg, for example, long-term leases often have a base rent that is 15 to 30 percent below the current market rent. When selling such a property, the lower actual rental value is factored into the capital value-which depresses the selling price. Buyers see this as potential for rent increases; sellers can achieve a higher capital value through targeted rent adjustments prior to the sale.

The key point here is that only rent increases that can be legally enforced-i.e., those based on the rent index or comparable evidence-actually raise the income value. An increase that is theoretically possible but has not yet been implemented is usually only considered by appraisers at a discount, as its actual realization is not guaranteed.

Factors that determine rental value

Location, amenities, year of construction, floor plan quality, and the general demand situation in the local rental market shape the rental value. In addition, rent control and the local comparative rent (rent index) play a role: The rental value may exceed the rent index, but rent control-where applicable-limits the rent for new leases to a maximum of 10% above the local comparative rent. These caps do not apply to commercial properties, which is why the rental value is negotiated more freely in those cases.

Energy efficiency is increasingly influencing rental value: Modernized apartments with efficient heating and good insulation command noticeably higher rents on the Nuremberg market than comparable properties with poor energy efficiency. With rising energy costs in recent years, this difference has grown-and it will be further amplified by the regulatory requirements of the EU Buildings Directive.

Feature sets also play a growing role: a built-in kitchen, balcony, parking space, elevator, and high-quality flooring justify surcharges on the base value of the rent index. Those who specifically upgrade their property before re-leasing it can significantly increase the achievable rental value within legal limits.

Rental Value, Rent Index, and Comparative Rents

A municipality’s rent index documents the local comparative rent for apartments of a certain standard. It is the most important public tool for determining rental value and provides guidance to both tenants and landlords. In addition, appraisers draw on comparable properties from listing databases and transaction records. For rented condominiums, the agreed-upon rent (actual rent) often differs from the rental value, which buyers must take into account when calculating returns.

A differentiated rental value assessment is particularly important for multi-family buildings with a mixed tenant base-partly long-term tenants with low existing rents, and partly units recently re-let at market rents. The weighted average of the actual rent and market value significantly determines the income value and thus the asking price.

In practice, the Nuremberg rent index provides values differentiated by neighborhood. An apartment building in Gostenhof has a different rental value than a comparable property in Langwasser or Schwaig. Those who know the rental value of their property and regularly compare it with the current rent index can identify potential for rent adjustments early on and, if necessary, initiate them in a legally compliant manner.

Practical Tip for Property Owners in Nuremberg and Franconia

In Nuremberg, the qualified rent index serves as the central reference; it is regularly updated and separately lists districts such as Gostenhof, St. Johannis, or Langwasser. Anyone looking to sell their multi-family home or their rented condominium should have the current rental value determined by an expert-outdated or below-market existing rents unnecessarily depress the determined income value and thus the asking price. We analyze for you whether and to what extent rent adjustments make sense before a sale and what effect they have on the selling price.

Frequently Asked Questions

What is the difference between rental value and the local rent index?

The local rent index documents the typical comparative rent in a municipality and is an official or recognized document. The rental value, on the other hand, is the market rent achievable in a specific individual case, which may be above or below the local rent index, depending on the property’s location and amenities.

How does a low rental value affect the selling price?

In the income approach, the rental value is directly factored into the calculation of the annual net income. A rental value set too low-for example, due to existing rents that have not been adjusted for many years-lowers the determined income value and thus the achievable sales proceeds.

Can I determine the rental value of my property myself?

The local rent index provides a rough guide. However, for a legally sound and bankable appraisal-such as for financing or estate settlements-a qualified appraisal by a certified expert is required.

Does the energy performance certificate affect the rental value?

Yes, increasingly so. Apartments with poor energy efficiency ratings (E, F, G) command lower market prices compared to similar apartments with better energy performance. With rising energy prices and regulatory requirements, this difference will continue to grow-landlords should keep a close eye on the energy efficiency of their properties.
