Hey Sal....I coach Realtors nationwide and in order to give the proper response to this question, I have tried everything on the market for a minimum of 6 months each, and most of them for a year.
Hands down, Homegain.com is the most beneficial, honest, well planned lead generating site out there.
The leads go out to everyone...you have the opportunity to submit a proposal to the prospective client who then chooses from the proposals with whom they wish to meet.
Create a strong proposal and be sure to "personalize" it with each response you give. I do a ton of business from Homegain every year and the more you do, the less the referral fee is.
If you wish to discuss further, feel free to contact me at email@example.com or call me at 631-425-6150...will be happy to "share."
