The value of an apartment building depends on its location, condition, floor area, leases and sustainable income, among other factors. The purchase price multiplier and net initial yield help compare offers, but do not replace a property-specific valuation.
This article shows how professional buyers derive the value of an apartment building – with the two decisive key figures, the purchase price multiplier and the net initial yield, a worked example and the factors that push the price up or down. That way you set an asking price that is actually achievable in the market – instead of producing time on the market.
At a glance
- ✓Value follows income, not living space – what counts is the sustainable net cold rent.
- ✓Purchase price multiplier = purchase price ÷ annual net cold rent. Gross yield is its reciprocal.
- ✓Rising mortgage rates push down the sustainable multipliers – the achievable price today is below that of the low-rate years.
- ✓Rental upside, condition and location decide whether buyers pay a high or a low multiplier.
The income approach beats the price per square metre
For a single-family house, the cost or comparison approach provides a usable reference point. For a let apartment building, the income approach counts: value follows from the capitalised net income – rent less non-recoverable operating costs, divided by the capitalisation rate the market applies to that location and asset quality. In practice buyers usually express this logic through the purchase price multiplier, the simplified other side of the same coin.
Multiplier and yield: the two key figures
Two figures govern the negotiation:
- Purchase price multiplier: Purchase price divided by the annual net cold rent. A multiplier of 20 means: the purchase price equals twenty times the annual rent.
- Gross yield: Annual net cold rent divided by the purchase price – the reciprocal of the multiplier. A multiplier of 20 equals 5.0 per cent, a multiplier of 25 equals 4.0 per cent.
- Net initial yield: Net income (rent less non-recoverable costs) divided by the purchase price including transaction costs. It is the more realistic yield measure institutional buyers work with.
Worked example: from gross income to purchase price
An apartment building with 800 m² of living space and an average net cold rent of 9 EUR/m² generates an annual net cold rent of around 86,400 EUR. The table below shows how purchase price, gross yield and net yield shift with the multiplier applied:
| Key figure | Scenario A | Scenario B | Scenario C |
|---|---|---|---|
| Annual net cold rent | 86,400 EUR | 86,400 EUR | 86,400 EUR |
| Purchase price multiplier | 22.0 | 20.0 | 18.0 |
| Purchase price | 1,900,800 EUR | 1,728,000 EUR | 1,555,200 EUR |
| Gross yield | 4.5% | 5.0% | 5.6% |
| Net income after deduction of non-recoverable costs (approx. 20%) | |||
| Net income p. a. | 69,120 EUR | 69,120 EUR | 69,120 EUR |
| Net initial yield (incl. 8.57% transaction costs) | 3.3% | 3.7% | 4.1% |
Simplified example. Non-recoverable costs (management, maintenance, rent default risk) assumed at a flat 20% of gross income; transaction costs vary by federal state. Not a valuation within the meaning of the ImmoWertV.
With annual net rent of EUR 86,400, one multiplier point changes the calculated purchase price by EUR 86,400. The assumed rental income and costs should therefore be carefully reviewed and clearly documented.
What pushes the multiplier up or down
Why does the market pay a multiplier of 24 for one building and only 17 for another? The decisive factors are:
- Location: Macro location (city, region, economic strength) and micro location (street, transport links, neighbourhood). The scarcer and more sought-after, the higher the multiplier.
- Rental upside: If the actual rent is below the local comparative rent, investors buy the upside as well – which lifts the multiplier. A rent already at the top of the local index limits it.
- Condition and deferred maintenance: Roof, façade, heating, pipework. Buyers deduct deferred maintenance from the price as investment – often more generously than it actually costs.
- Energy performance: The energy certificate, heating technology and refurbishment obligations feed directly into the follow-on costs buyers calculate.
- Tenant structure: Solvent, long-standing tenants and healthy turnover reduce risk; vacancy and problem tenancies depress the multiplier.
- Site and planning law: Reserves for densification or a loft conversion can lift value beyond pure income.
Why interest rates move the achievable price
The multiplier a buyer can pay depends directly on their financing costs. As long as let assets are debt-financed, the yield has to exceed the interest rate for the purchase to work. When mortgage rates rise, buyers demand a higher yield – and a higher yield means a lower multiplier, that is a lower price for the same rent. The mechanics behind it – policy rate, Bunds, inflation – are explained in the article Why mortgage rates are rising.
Asking price: realistic rather than ambitious
Ein Angebotspreis, der noch auf Vergleichswerten aus den Boomjahren beruht, produziert heute vor allem eines: Liegezeit. Objekte, die monatelang sichtbar unverkauft bleiben, werden vom Markt kritisch bewertet – Käufer wittern einen Mangel und verhandeln erst recht. Umgekehrt zieht ein Preis, der am heutigen Zinsumfeld und an belastbaren Erträgen ausgerichtet ist, die richtigen Käufer an und führt zügig zum Abschluss. Ein spezialisierter Vermittler, der die tatsächlich gezahlten Faktoren Ihrer Lage kennt, ist hier mehr wert als jedes Online-Wertgutachten.
Frequently asked questions about the value of an apartment building
Income value or cost value – which counts?
For the sale of a let apartment building, the income value counts. The cost value (land plus building reconstruction value) serves at most as a plausibility check, or becomes relevant for assets let well below market.
How do I find the right multiplier for my location?
Asking prices from portals say little; what matters are the purchase price multipliers actually paid for comparable assets. Valuation committees, market reports and – most reliably – an adviser with a live view of transactions provide these figures.
Does selling with or without tenants increase value?
For investors, a let, income-producing building is the normal case and usually the preferred one. Only for assets with strong upgrade or subdivision potential can partial vacancy raise value for certain buyer groups.
What is a “good” multiplier today?
There is no blanket answer – it depends on location, condition and rental potential and shifts with the level of interest rates. What matters is not an abstract target multiplier but the price buyers with secure financing pay for your specific asset today.
Before setting the price
- ✓Sustainable net cold rent determined – including vacancy and default risk?
- ✓Non-recoverable operating costs applied realistically?
- ✓Rental upside against the local comparative rent reviewed?
- ✓Deferred maintenance quantified honestly before buyers deduct it generously?
- ✓Asking multiplier checked against multipliers actually paid and against the rate environment?
