Tried them a while ago. The seller was under the impression that the house would be listed for free, she said lead to Realty assured her the agent would "take care of that".
The next seller was an apartment dweller with no property. He may work out as a buyer in a year or so, he at least follows up with the me and the Lender. So who knows.
The few other leads never panned out. One of them I was convinced it was a kid playing on the internet.
I do give LEad To Realty credit in that when I complained, they immediatly suspended my account and stopped billing me without hassle. They would not refund me money back, just credits for future credit if I chose to to reactivate my account. I did not really need the leads but they came highly recommended.
