Yes, not sure how exactly his system works, but usually for such sites, you buy exclusive rights to a county and pay per lead or per month. They range from $35 to $70 per lead, and upwards of $2000 per month.
What you get in return is any submitted house for sale online. Go to a search engine and type “we buy houses”, that is basically how they work.
You have to see how much per lead is it costing you now before you find a good deal. It may not be for everyone, but it could turn into a deal or two per month depending on how good you are at closing deals. I subscribe to such service, and I must say, most if not all so far have been tight deals. I don’t mind that since I do sub2, but it may not be so good for deep discounters or rehabbers.
