Do you want to be on call 24/7?
Are you willing to field 50-75 of these buyer calls before closing a transaction?
Are you willing to pay additional money for a tool like Follow Up Boss which will ensure that the money you spend on the leads is not wasted but that a powerful response plan and long-term follow-up plan is instantly launched for each and every leads that comes in?
If you answered "No" to any of the above, then this might not be a good source of leads for you. If, however, you can say "YES! I'm cool with that!" then it might be something worth doing.
