I entered a one year contract with Market Leader/ House Values/ Just Listed for house buyer referrals at $159 per month billed to my credit card. They often did not send the agreed number of referrals and those they did send were largely fictitious referrals of non existent persons.This service is a rip off. The National Association of Realtors gave these people credibility by allowing them to advertise in the NAR magazine which sullies the NAR of which I am a member.
