Building buyers list

[Eric Kluth]

I have a list of buyers that bought properties within a year in my area. Im targeting small multifamily properties between 5-50 units. The list is roughly 80 buyers. I have done my first mailing campaign, a yellow letter in an invitational envelope. I have done a couple craigslist postings. So far i have no bites. I don't have a website yet. Any advice on getting buyers to respond? Whats the most effective strategy?
