Hi John,
The leads I subscribed to were for single family houses mainly but some of the sites offered commercial, apartments and land. When I spoke to the property owners the majority have an urgency to sell fast but there were a few who didn't call back or were just entering information to see what would happen.
I really like getting leads this way because the property owners were essentially coming to me to tell me they needed to sell vs. me having to send out a bunch of direct mail letters or postcards trying to find motivated sellers. I'm not saying that you shouldn't do this type of marketing as well but I feel my time is very important and I'd rather spend it on other things that will help my real estate investing business.
I've done other marketing and didn't have nearly as great of success as I did subscribing to these sites.
Incidentally I'm not subscribing now because I'm taking a break for awhile and focusing on other areas in real estate right now.
Regarding price point - in all my research I did not find anything below $30 per lead (for fresh leads) and frankly I didn't expect to. I know a lot about internet marketing and I tend to be slightly skeptical of anything advertised as free or cheap. In my experience, in order to get something good, you usually need to pay reasonably for it.
Just my two cents!
