Rented apartments in Germany



New Member
I 've got a couple of questions about properties in Germany. Can someone, please, help me with some info?
Firstly, I need to know if it is safe for a foreign person to buy an already rented apartment with people living in it. Is there any risk of any kind?
Next, If you do buy a rented one, who pays the Hausgeld - the owner or the tenant ? I suppose that should be divided between the two parts as the one who lives in the apartment is the one who consumes water, electricity, etc. which are included in the hausgeld, but the part of the hausgeld that goes to pay the administrator and maintenance of the building are to be paid by the owner.
I would appreciate any info you could provide.
Many thanks beforehand.
