Leads that come complete with all the information you could possibly need can be considered easier. These leads come ready for you to get on the phone right away and get working. On the other hand, leads that have the bare minimum of information provided require you to obtain it.
Consider this, leads with less information are, in the long run, more expensive because they cost you time to track down information that you need to call them. Therefore, it makes sense to spend a few more marketing dollars initially, in order to buy virtually guaranteed leads that are ready.
Of course, it is your choice when picking which type of lead you want to pursue. Knowing the real cost of obtaining leads and conversions will help agents determine what is best for their work style and the future of their agency.
