An all-in price means that the landlord only gives you a total amount for the rent. This way you don’t know what your bare rent is and what you pay for service charges, for example.
All-in rents are not desirable. With only a total price you cannot determine whether the bare rent is justified or whether you are possibly paying too high an advance for the service costs.
An all-in price can never be liberalized because the bare rent is unknown. The bare rent is essential to determine whether it is a liberalized rental property. For the same reason an all-in price may, in principle, not be increased.
You can request your landlord to divide the all-in price into the bare rent and service costs. If the landlord does not honor that request, you can contact Rent Support Center Groningen.
The Rent Support Center can mediate with your landlord or help you present the case to the Rent Tribunal. That process could result in a lower rent.
