BP,So I have come to the realization that I am going to have to do some kind of mail marketing campaign in order to start up my wholesale business.

Someone wrote a good summary of the zoning process in the forums, but I can't find it right now.edit: maybe look up your property on atlas (atlas.phila.gov), see who the RCO is (under zoning), and e-mail the contact to see what they think your odds are of getting the 3rd story.

But one thing I would suggest is to talk to and get on the mailing lists of all the biggest brokers like Marcus Millichap and CBRE.

Plus, there is no question or despute for the old story of the "check is in the mail."

I landed my first couple of deals from skip tracing the returned letters from my mail campaigns.

Philadelphia told him he can go home and they will mail out all necessary documents to his home.  

Or should I wait and send it via mail?  

Of course it's by  they’re not going to give you the off market right away, but you've got to start right from the first impression and then after ten days you go again call them, text them, e-mail them “Hey. by the way, I'm Richard or I'm Tim, I'm Vinnie and I just want to follow-up for sending me that property or I looked at it and it really doesn't fit my criteria, and why does it not secure criteria.”

I have a lot of calls from a direct mail campaign.  

Do it legal and have the law AND a judge on your side.p.s. send the notice via certified mail.
