As soon as the property has been transferred to the lessee, the rights and obligations of the lessor of the lease are transferred to the new owner of the property, in accordance with the Debt Act. In other words, for example, if you have moved as a tenant into a rented apartment, the apartment is in your possession and the lease is automatically transferred to the new owner. If the new landlord wants to enter into a new lease with you after the purchase of the apartment, there is really no need to do so. For example, such a topic may be on the agenda if the new landlord wants to change the contractual terms for you – for example.B. to increase the rent. If you do not want to enter into a new contract, the new owner of your apartment only has to accept the situation or terminate the lease. A rental contract of indefinite duration can normally be terminated with a period of 3 months. This means, however, that if the new owner still exercises this right of withdrawal under a fixed-term rental agreement, you can claim damages from the new owner under the sales contract. In other words, if the tenant is wronged, you must always resurrect the disadvantage for the tenant.
