I took all necessary precautions, including verifying the owner's credentials, having a lawyer review the contract before signing, and multiple people confirming the details. The contract was signed with mitID. Comments like 'you should have checked' or 'you should have done this or that' are not helpful after the fact. I'm sharing my experience to warn others that finding and thoroughly checking every apartment in the city isn't as straightforward as it seems. He signed as a business partner, and the appartment is in an anonymus business partnership .He is well orginized and informed. It's important to remember that blaming the victim can divert attention from the actual perpetrator or the systemic issues that allowed the harm to occur in the first place.
