Marketing to Pre-Foreclosure properties: Post Card or Envelope?

[Shawn Ward]

BP Investors,

I am currently closing on my next flip acquisition (in escrow now, should close next Tuesday) and already looking for the next deal. 

QUESTION: I was recently able to acquire two lists from an associate of mine:

1. Eviction Records

2. Tax Lien/Pre-Foreclosures

I have all of the names and addresses (this is in California) and about to market to them. I wanted to know if anyone had suggestions based on success or not on the best way to market to these home owners? I was thinking a post card, but they can look a bit promotional and get thrown away pretty fast. Then I thought, maybe I'll type a letter and put in an envelope that I HAND WRITE on the outside so it looks a bit personal. But not sure. 

Anyone have any suggestions? Totally open to what works...and I know its a numbers game, but wanted to know the most efficient way to reach out. 

Thanks in advance!

Shawn
