Valuing apartment buildings

Jens Krüger, property valuation expert

With an apartment building, income is what counts in the end. I assess rents, operating costs, condition and remaining useful life together – the way the market assesses such a building.

For apartment buildings, floor areas and sustainably achievable rents are among the key value drivers. For a proper valuation, however, they have to be considered together with the plot, the tenancy structure, operating costs, condition, remaining useful life and conditions in the local property market. As an expert, I examine these relationships for the specific property – for an inner-city rental building as much as for a residential complex on the edge of town.

The focus is generally on the property’s sustainable income potential – not simply on the total of the rents currently agreed.

Assessing sustainably achievable income correctly

With apartment buildings, the focus is generally on the property’s sustainable income potential. What matters is therefore not only which rents are currently agreed, but which income can be assumed on a sustainable basis, taking into account the specific property and the local property market.

Particularly relevant may be the current net rents excluding service charges, lease start dates and rent development, flat sizes and unit mix, let and vacant units, parking spaces and garages and other let areas. Differences between contractual rents and market rents can also matter for the valuation.

The tenancies are considered from a valuation perspective; this does not replace a review under tenancy law.

From gross income to sustainable net income

In the income approach, the operating costs to be applied in line with the valuation model are taken into account. Depending on the model, these include in particular management costs, maintenance costs and the risk of rent loss, and where applicable other non-recoverable costs.

Which inputs are appropriate depends on the property, the valuation model and the relevant property market data.

Property yield and market-based capitalisation

For apartment buildings, the income approach (Ertragswertverfahren) is generally a key valuation method. Put simply, it examines what sustainable income can be expected from the land and building and how this income is to be capitalised, taking into account the remaining useful life and a market-based property yield (Liegenschaftszinssatz).

The property yield cannot be chosen freely. Where suitable property market data is available, it must be applied consistently with the model from which it was derived. On the importance of model consistency, please see the guide ImmoWertV & ImmoWertA.

Land value, plot utilisation and plot characteristics

The standard land value is not automatically the same as the land value of the specific plot. Plot size and shape, type and density of permitted development, servicing and other characteristics affecting value may have to be taken into account. With larger plots, the existing or possible level of development can also play a particular role.

The basics and distinctions are explained in the guide standard land value & land value. Rights affecting value such as a right of residence or usufruct and heritable building rights may also have to be taken into account, depending on the property and the task.

State of modernisation, maintenance needs and floor areas

With an apartment building, the state of modernisation and foreseeable capital expenditure can have a considerable influence on the economic assessment. The roof, facade, windows, heating system, pipework, electrical installation, staircases and balconies, among others, can affect value. The expert valuation does not replace a full technical building survey.

Living and usable areas are also a key basis of the valuation. Incorrect area figures can affect both the rents applied and comparison ratios. If there are doubts about existing figures, a separate floor area measurement may make sense.

Not all vacancy is to be valued in the same way

A flat that is empty between two tenancies has to be assessed differently from a unit that cannot be let in the long term or from structural vacancy. Temporary vacancy may also be related to modernisation or re-letting.

For the valuation, what matters is therefore not only that a unit is vacant, but why it is vacant, how long this is likely to last and what sustainable use or lettability can be expected in the market.

Extension reserves and other possible uses

Attic conversion, additional building potential, changes of use or other development potential can affect value. However, they should not be included in the valuation merely because they are theoretically possible.

What matters is whether the potential can be assessed with sufficient certainty in legal, structural and economic terms. Unsecured hypothetical floor space is therefore not treated in the same way as existing usable or lettable space.

Which valuation fits an apartment building?

Short-form valuation

Depending on the size of the property and the task, a valuation with more compact documentation can be agreed individually.

Full market value report

For a comprehensive investigation, derivation and documentation of the market value. For apartment buildings, the scope and fee are calculated individually.

Pre-purchase consultation / pre-acquisition assessment

For apartment buildings, the scope of a pre-purchase consultation or pre-acquisition assessment is agreed individually according to the property and the task – with a view to purchase price, income, condition and investment needs.

Which documents are needed?

Depending on the property and the instruction, the following are particularly helpful:

  • Land register extract
  • Cadastral map
  • Building drawings and floor plans
  • Living and usable area calculations
  • complete tenancy schedule or rent roll
  • Leases or relevant rent details
  • Details of vacancies
  • Details of management and operating costs, where required for the task
  • Overview of modernisation and major repairs
  • Energy performance certificate, if available
  • Information on rights and encumbrances
  • documents on extension or development options, if applicable

For larger or more complex properties, further documents may be required depending on the task. Not everything needs to be complete at the first enquiry.
