One of the features of Dan.com is that buyers can utilize a lease to own (LTO) payment plan to buy a domain name over a set period of time. Each month, the buyer makes a payment for the domain name until the domain name is paid-off in full. Payment plans can be as short as a few months or as long as five years. The Dan.com TOS covers some of the prohibitions
I’ve been under the impression that a LTO buyer can not actively sell a domain name before the purchase is paid in full. Outbound marketing of a domain name can be risky. For instance, attempting to sell a 3 letter .com domain name to a company that uses the 3 letters as its acronym or brand can lead to the company filing a UDRP or ACPA lawsuit. The company could cite the outbound email pitch as proof of bad faith registration.
