We do not have "Agents" that will meet you at your rental or provide any "Delivery of Key(s)" services.
If a Landlord/Homeowner is mentioning any of these services, then this is most likely a Scam. Please do not send funds via wire or Western Union.
We strongly suggest to you that you report this fraudulent listing to the website that you you found it on and also report it to your local authority.
Please let us know if you have any further questions.
