Thanks for your elaborate answers. here in Germany the fees are sometimes in the range of 1 - 2 monthly rates. The last one is the maximum allowed value by law. But, as you have to pay a damage deposit to your new landlord as well, this might add up in cost around 5 monthly rents. OK, if everything goes well, the damage deposit returns to your valet, once you move again, but that is a lot of money to have at hand upfront.

So a service like this will help a lot of people - as said before.
