What we take care of

Long-term or short-term? It depends on the home and the rules. That is why we work out both options before you choose.

Do you have several units?

We rent out and manage every tenancy with the same processes and the same reporting, whether you have one home or several. The fee is the same for each tenancy.

In Mit BY (in Danish) you follow all your homes on one login, with the lease period, rent, lease and statements for each home. If you own the homes through several companies, or both privately and through a company, you see each customer number separately on the same page.

If you are thinking of buying more, we go through the rules and the finances with you before you buy.

Do you have new homes to rent out?

Which rules apply to the rent depends on, among other things, when the building was first used. For apartments in buildings first occupied after 31 December 1991, the rent can as a rule be agreed freely under section 54 of the Danish Rent Act (lejeloven). In older buildings, special rules apply to the level of rent.

The rent still has to be in line with the market if you want a tenant who stays. We set the rent based on current market data and local insight, within the limits of the Rent Act.

In Copenhagen Municipality, newly built homes can be subject to the residence requirement (bopælspligt, a duty to have someone living in the home) as early as six weeks after construction is completed, if the local plan (lokalplan) was adopted after 1 January 2021.

This page is general information, not legal advice. The rules change, and your situation may differ.

Frequently asked questions

Answers to what landlords ask us most.

Have another question?Call +45 50 52 15 37 or book a meeting.

Do you work with investors and portfolios?

Yes. We work with private landlords and investors with several units, and the service scales with the size of the portfolio, with the same processes and reporting.

What does it cost?

17% of rental income for short-term rental and 8.5% excl. VAT of the rent for long-term rental. Cleaning, linen, supplies and maintenance are billed separately at cost or at agreed rates. No hidden fees. The platform’s fee, such as Airbnb’s, and any payment fees are deducted from the payout and are not part of the 17%.

See all prices
Does the 70-day rule cover a home I own as an investment?

No. The rule covers your own permanent residence, meaning the home you actually live in. If you own two homes, it only applies to the one that is your permanent residence. A home subject to the residence requirement (bopælspligt) that you do not live in yourself may not be used for holiday rental without the municipality’s consent (section 7(1) of the Housing Conditions Act). Before we take it on, we look at location, the building and association rules, layout, furnishing and demand in the market. If your home suits mid-term or long-term rental better, we will recommend that instead.

See the Airbnb rules
How do I follow the finances when I have several homes?

Every month you get a statement of income, costs and net result. In Mit BY (in Danish) you follow all your homes on one login, with the lease period, rent, lease and statements for each home.

Which areas of Copenhagen do you cover?

All of Copenhagen, from Indre By, Christianshavn and Vesterbro to Østerbro, Nørrebro, Frederiksberg, Valby, Nordhavn, Sydhavn, Islands Brygge and Amager.

Applies to new management agreements entered into up to and including 31 December 2026. A few one-off services at the start, such as photography, styling, a key box and a deep clean, may be billed separately by agreement.
