On Monday I want to start contacting realty agents, brokers, mortgage brokers, loan officers, and title insurance companies to let them know I'm an investors and would like any distressed property referrals they may have. What are some great incentives that work with these group of professionals?

I know after I call them, they may just forget. So should I send a handwritten (or typed) note or a fax to follow-up? Is e-mail just as effective?
