Direct Mail in Philadelphia - Saturated?

[Jibu V.]

From almost every recommendation I've seen, it sounds like direct mail is the best way to generate leads for rehabbing and wholesaling.  My concern is this:

Philadelphia (in and around) is flooded with bandit signs.  I am presuming that it is also flooded with direct mail.  What kind of success are people currently having with direct mail in Philly?  

I hope to start off with 1000 mail pieces per month.  The main thing holding me back right now is a belief that the Philly market may be saturated with these mailings (sounds like everyone is buying a listsource list and marketing to vacant owners "with equity") and sellers are using it to their advantage to have investors bid against each other and make deals less appealing.  Am I thinking about this the wrong way?

Thanks in advance for any feedback.
