Before it became a policy, the company had several issues collecting payment from tenants as many of them believed it should be their landlord's responsibility, and probably their landlord thought otherwise. To avoid such an issue, it became a matter of policy to collect credit card info if the service location is a rental property, and the person receiving the tech during the service call isn't the property owner. The same rule applies to places of business to make sure that the company gets to collect payment after the service call.
