Direct Mail KPI - Wholesaling

[Amani Clarke]

Hi guys I'm thinking about trying out direct mail for lead generation in my wholesaling business. I was thinking about driving for dollars to build a list of at least 3,000 properties. I have about $18k to spend on the marketing to try and yield a return. I know that it's recommended that I send in batches which is what I'll likely do. I spoke to a very successful real estate investor/ broker in my market and he said he's finding great success with sending mailers 6 times to a list every 21 days. 

I was curious to know 

1) How many letters are you sending out to convert one closed deal? And how often?

2) How much are you spending to get the deal compared to the average assignment fee?
