In today's world, for a house to be habitable, services such as electricity, water, and natural gas (if there is no other type of heating) are required. Internet service can also be added to these services. Therefore, when moving after buying a new house, registration of these services should be made. To access these services, municipalities and/or companies are waiting for the new landlord to insure against natural disasters, DASK. After receiving the DASK certificate, an application is made for these services to the institutions serving the area where the house was purchased, along with other necessary documents. Tenants are obliged to make subscriptions for houses purchased for investment purposes, so the landlord does not need to open a subscription.
