I’m sorry if this question doesn’t belong here, but couldn’t figure out where else to write and this community doesn’t have a rule against english posts so decided to ask here:

Are landlords in Austria required to pay back the rent deposit with interest ? And if so, is the interest rate tied to something specific? Or are all of these things contract specific and the landlord by default is not required to pay back the deposit with interest to the tenant (if the tenant hasn’t caused any damage that would allow the landlord to keep the deposit obviously)?

I tried googling and translating some pages without success, and my German skills are limited to oida gemma zu billa so I thought maybe someone here could help.
