NAR did a study on the home buyer and here's the stats for you fellow realtors...
It takes 4.8 weeks for the consumer to be ready for more contact from a realtor.
52% of those consumers prefer EMAIL contact only.
88% expect an immediate response.
You need 11-17 touches (email, mail outs, etc) for the average consumer to remember your branding.
This last one hurts- Realtor lose 40% of there contacts every year! WOW!
