Thanks for sharing your insight about this topic.
Also do domain brokers provide such leasing facility , i mean to say will they assist in finding suitable lease requirer and how lease rate be decided?
also at present what's the lease rate?
Do you mean a company that will rent your domains for you?
I'm not aware of any such site, but as for the rates, it's anything you agree upon with your buyer/renter. In the domain world, you can ask for pretty much anything as long as somebody is willing to pay that much. It's still smart to keep your price fair and reasonable though or you won't get any bites.
