Direct Mail : Best lead source? Distressed homes or lists?

[Thai Le]

Hi everyone,

I'm on my 5th week of a tiny direct mail campaign here in Phoenix, AZ. I've mailed 250 people x5 weeks yellow letters. They were distressed houses that I found driving around. 

I've gotten only 2 inquiries about selling thus far. What are your 2 cents, everyone?

1. Is it just that I have to continue mailing beyond 8 weeks?

2. Anyone having success from mailing your distressed homes? Have you found it more efficient to use your local title company for a mailing list? Are they the same?
