It has credit cards and bank accounts.  

I am looking for a format or template where all of the generic text is on the card and then I could run it through my printer to add property address and owner's name/address via mailmerge.

If you want the post cards to come back, just place "Address Service Requested" under your return address or under the postage that you add.

As far as wholesaling goes, I have listened to the gurus, purchased an LLC for my company, Nobility Real Estate Investments, got the website (www.nobilityrealestate.com), business cards, instagram page the whole 9.

This includes my house, car, and credit card.

Credit card or personal bank loan would work also. 

Business Card front, stick front door and car doors in drivewaysin Listeds, Expireds, FSBOs, FRBOs,Write on the back,I have a Buyer on Lease Purchase for you! 

With some business cards in hand and only $400 left to my name before the bank is dry (I have some deals in the works that should give me a decent chunk of change here soon) I want to generate more quality leads.

We do not have any credit card debt.

I would position my self very differently with a seller, buyer, or agent vs banker for example.I generally call myself a wholesaler but my card has no title or description just contact info.
