I have a really simple post that you can put on facebook. you can post in groups that you are a part of or on your personal page. The results of the post will generate potential leads for you and best of all it is free and the leads that you get from it are free since you are just posting and not paying for advertising. Send me a message through the contact page if you would like the simple post and I will email it over to you.
The last agent that posted it told me that they got 9 leads in the 1st 30 minutes and they were all free.
