Rental agreement and payment

In all Koas housing locations, electricity, water, internet connection, weekly sauna and use of laundry facilities are included in the rent.

The rent is due on the 6th of every month. Always use your personal payment reference number and check that the amount payable is correct. The rent bill is sent by email and the payment details are valid until further notice. Didn't receive the bill in your email? Please contact vuokrat(at)

If you don't have a bank account in Finland or you can't use your own account, you can use TransferMate - KOAS for rent payments.

Late rental payments

If you have any difficulties paying your rent, please contact vuokrat(at) or call 029 180 4444 to agree on a payment schedule before the due date of the rent.

Late payments are handled by Visma Duetto. If we don't receive the payment on time, you'll first receive an email from Visma Duetto. Notification will be sent around 14 days after your rent was originally due. A notification charge of €5 will apply.

A history of late payment may lead to the annulment of your contract, debt collection and a bad credit history. Loss of creditworthiness will remain on your record for a long time, and it can make your life significantly more complicated in the future. You can prevent problems by paying your late payment notices by the due date.

We charge interest on the rent arrears at a fixed rate determined by Finnish law. Interest will start accruing from the day after the due date, regardless of any payment plans made. Interest fees will be invoiced separately.

Joint liability

Spouses share liability for the rent of their family apartment, as does anyone else living in Koas housing with a joint rental agreement. If one person moves out, the joint rental agreement needs to be terminated. Joint liability continues until termination of the rental agreement.

Tenant eligibility

Living in Koas housing entails that the tenant is registered as a student or a graduate student in secondary or tertiary education. For couples living together in Koas housing, at least one person must have student status. Koas will verify the student status of the tenants regularly and whenever deemed necessary. When you no longer meet the criteria for Koas residents, please make sure you terminate your tenancy in good time. If your studies are interrupted, please contact the Koas housing office.

Rental agreement

Your rental agreement can be valid until further notice or for a fixed term. The rental agreement is signed in the Koas housing office, or is sent to you for signature by post or email. For tenants under 18 years of age, parental signature is also required. For family rental agreements, both spouses or cohabiting partners are required to sign.

By signing the rental agreement you agree to abide by the terms set out in your agreement, Finnish law on residential agreements as well as the House Rules drawn up by Koas residents.

Fixed term rental agreements for exchange students are confirmed by paying the first month's rent + the furniture fee + the processing fee.

Verification of contractual obligations

As a tenant you are obliged to notify Koas if there are any changes in your personal circumstances or details you have given to Koas at the time of signing the rental agreement (for example finishing or leaving your studies early). Giving false information or refusing to provide information may result in termination or annulment of the rental agreement.

Annulment of the rental agreement

In the event of serious contract violation, Koas may exercise the right to terminate the rental agreement without a notice period. These eventualities include non-payment of rent, constant and excessive disturbance, transferring the tenancy or handing the apartment over to another person without permission. The rental agreement will expire one week after the termination notice is issued by Koas.

Temporary subletting

Koas allows tenants to temporary sublet apartments to a third party for a maximum of 1 year. The subletting tenant needs to be a full-time student except during the summer months (May 1 to August 31).

If you wish to temporarily sublet your Koas apartment, do as follows:

  1. Draw up a fixed-term rental agreement with the subtenant. Set the date of the rent payment as the 2nd of every month. Arrange for them to pay the rent into your account so you can keep track of their rental payments. The rent collected from the subtenant may not exceed the amount of rent paid to Koas.
  2. Contact the Koas Housing office by email koas(at) to notify them of the subtenant's name, personal ID (henkilötunnus), email address, phone number and the duration of the subletting agreement.
  3. Give the subtenant temporary use of your KOAS Booking log in details. You as the main tenant are responsible for possible paid services, such as parking, used by the subtenant. Remember to make sure you both receive important Koas information during the subletting period.

You as the main tenant are responsible for the rent payments and the condition of the apartment. You are required to notify Koas of any changes to your rental agreement.

In a shared apartment, subletting is only allowed to someone of the same gender.

Rent deposit

Tenants have not generally been required to pay a deposit since June 1, 2018.

A deposit is only required if a tenant has credit history problems. The deposit is paid before signing the agreement, by the date specified in the housing offer. The deposit is paid by the tenant to ensure they fulfill their responsibilities agreed upon in the rental agreement. Koas may deduct any possible cleaning or repair costs or unpaid rent from the deposit.

Refunding the deposit

The deposit will be returned to the tenant in full on the condition that all the tenant's obligations have been met. The deposit will be returned to the bank account specified in the Termination of Tenancy request, within a month from the day tenancy ends. The rent deposit cannot be used to pay the last month's rent.
