The numbers

Price divided by annual rent: one figure, two names.

Divide the purchase price by the annual rent excluding heating and ancillary costs and you get the price-to-rent multiplier. Turn the calculation round and you have the yield. Maintenance, management, loan and taxes still have to come off that.

These figures come from sales of multi-family buildings that actually went through. The asking prices and rents for owner-occupied flats work out at around 31 annual rents (IBB Housing Market Report 2025). The gap is not a negotiating discount: different property types are being compared.

How we help: We work with the rent stated in the tenancy agreement, not the rent someone is asking. If you already own a flat, we assess it using the same calculation: Request a valuation.

Financing

The interest rate helps decide what remains of the income.

Besides price and rent, the monthly instalment, the fixed-rate period and the repayment determine what is left of the rent. Repayment is the part of the instalment that pays off the loan. How interest rates and conditions in Berlin have developed is shown in the market data.

Commission and contract

As a private individual, you are a consumer, even when investing.

You pay at most half

Since 23 December 2020, private buyers of an owner-occupied flat or a detached house pay no more commission than the seller (§§ 656c and 656d BGB, German Civil Code). If only the seller instructed us and you take over part of the commission, you pay later than the seller. The seller must have paid first, and we must provide you with proof of this (§ 656d para. 1 sentence 2 BGB).
The agency agreement requires text form, for example an email. A commission notice in an email signature is not enough.
If the agency agreement is concluded without meeting in person, you may withdraw from it. You receive the information on this before we work for you.

Where the line is drawn

If you buy through a company or as a business, this split does not apply. We then agree the commission before marketing begins, and it is set out in the agency agreement. The text form requirement under § 656a BGB still applies.
It never applies to apartment buildings, plots and commercial property. If a private individual buys several flats at once, we check it case by case. See Apartment building and Portfolio and packages.

Law relating to the property

Four rules that determine the income.

Rent cap (Mietpreisbremse)

When you re-let, you may charge at most ten per cent more than is usual in the neighbourhood (§ 556d BGB; Mietenbegrenzungsverordnung, the rent limitation ordinance for all of Berlin, valid until the end of 2029). Exceptions: new builds from October 2014, the previous tenant's rent, a modernisation.

How we help: Before the purchase, we check whether the current rent matches the usual level in the neighbourhood. And whether an exception applies. Guide: rent cap

Levy after a modernisation

If you have modernised, you may add eight per cent of the costs per year to the rent (§ 559 BGB). Over six years, this may raise the rent by no more than three euros per square metre, or two euros if the initial rent is below seven euros. If you replace the heating with the help of subsidies, it is ten per cent and no more than €0.50 per square metre per month over six years (§ 559e BGB). Normal repairs do not count.

How we help: In the minutes of the owners' meetings, we separate repairs from modernisation before you count on a levy. Guide: modernisation levy

When the tenant has priority

If a let building is divided into individual owner-occupied flats, the tenant may buy their flat first (§ 577 BGB). After that, in Berlin you cannot give them notice on grounds of personal use (Eigenbedarf) for ten years. The period is counted from the sale (§ 577a para. 2 BGB; Berlin Kündigungsschutzklausel-Verordnung, the eviction protection ordinance, valid until 30/09/2033).

How we help: Before the purchase contract, we clarify whether the flat comes from such a division and whether the tenant has priority. Guide: right of first refusal

Social preservation areas

In 82 areas of Berlin, the district protects residents from displacement; this is called Milieuschutz, or social preservation area (Geoportal Berlin, as of 16/09/2026). Anyone who demolishes, converts or changes the use there needs approval (§ 172 para. 1 BauGB, Federal Building Code). It is granted if the conversion brings the flat up to the standard of an average flat (§ 172 para. 4 sentence 3 no. 1 BauGB). If you buy a single owner-occupied flat, the district has no right of first refusal (§ 24 para. 2 BauGB).

How we help: We check the address before the purchase contract and tell you what modernisation is still permitted there. Social preservation map (Milieuschutz) with address check

Frequently asked questions

Flats as an investment: frequently asked questions.

Answers as of 20 September 2026

Do I also pay half the commission if I want to let the flat?

Yes, as long as you buy as a private individual. What matters is who buys, not what you later do with the flat (§§ 656c and 656d BGB, German Civil Code). The agency agreement requires text form, i.e. at least an email (§ 656a BGB).

What return does a flat in Berlin bring?

Multi-family buildings in Berlin recently cost a median of 21.1 annual rents, and 24.5 in Charlottenburg-Wilmersdorf (Guthmann Estate, as of 2026). 24.5 annual rents correspond to around 4.1 per cent a year, before any costs are deducted. We cannot guarantee that. It depends on your loan, on maintenance and on your taxes.

May I increase the rent after the purchase?

Only within narrow limits. The rent cap (Mietpreisbremse) limits the rent when a flat is re-let. The rent increase cap (Kappungsgrenze) limits increases during an existing tenancy. After a modernisation, you may pass on part of the costs. If you demand too much, the tenant can object.

How do I find out about flats that are never advertised?

Through the investor search profile. Anyone who has told us in advance what they are looking for hears from us first, even before a possible listing.
