I generally sell domains. I have offered payment plans where they can use the domain immediately but it doesn't get transferred until final payment is made. Leasing would work good for seasonal domains or super premium ones where you would rather have a monthly cost than some x,xxx,xxx purchase on the books. Few years ago leasing kinda made a splash with LeaseThis.com but didn't seem to do anything significant, seems to be a push for leasing lately in the mainstream world so see if it has wings this time around. I have never leased only offered payment plans for purchases.
