1) Do you have the rental agreement with the stamp duty paid? Not sure what you mean by "stamped" I assume that stamp duty is paid.
2) Do you recall if the bank authorised the landlord to rent the apartment - this is the sticky point. Owners are supposed to get bank authorisation if they're renting their mortaged property. If not, then there may be a problem.
You do need to be concerned. This happened to me about 15+ years ago. Luckily a good friend of mine was an MD at the bank and he put me in touch with their collections person.
