Z-buyer is probably the best lead generation site out there. The leads are all over the board but then again for $120 a mo, what do you expect, someone else to filter them?
I get about 40+ leads a mo. Now they have started adding buyer leads as well, awesome. So you pay $1440 a yr for the service, get about 500 leads a year. let's say you really are bad at Real Estate so out of 500 you get only 1/5th of 1% to buy or sell.....1 sale in 12 months.
Lets say that sale was only $150,000 and your commission $4000. In 12 months you invested $1440.00 and turned it into $4000.00. That is a 36% return on your investment for ONE SALE! Try that in the stock market. Time spent calling leads, well at about 1.25 leads a day, maybe 5 minutes a day, unless they are good.
Now imagine your sales skills are ok and you sell to or for 3% of the leads.....15 sales...you do the math.
The reason people do not succeed is not the program, it is the lack of action, daily, regular, consistent action. if you do the work, anything will work.
