I called simply to confirm whether a property was still available to rent - and if so, ask a few short questions about it. Instead, I was immediately interrogated for sensitive information, e.g., my job title and salary. To be clear, I hadn't asked to view the property. But rather than help, they chose to "qualify" me first - presumably to help them decide whether I was worthy of their time. Of course, tenants are ten-a-penny, so my refusal to comply will make absolutely no difference to them. Bottom line: unless you're a landlord, you're just not important. Be warned!
