I used true stamps.

gaswcc.org/docs/eands/IARSTREAM509.pptThe first step will be to have a Professional Engineer draw and stamp the proposed design to submit to DeKalb.

So various counties kicked back the mortgage and deed claiming they wanted doc stamps on the entire line potential per property. 

Maybe you can send your last tenant a survey and a $5 bill asking why they moved, how much their utility bills were and what improvements could be made....for the next tenant  and say you regret losing a great tenant so they feel complimented maybe...self addressed stamped envelope for return.       

I know there are certain fixed costs that will be on every house no matter the purchase price (processing, inspection if I get one, document preparation fee, survey) and some variable fees that I have a % worked out (title insurance, doc stamps on mortgage ect).

Yellow letter I'd print a bunch of blanks with the chosen persons handwriting then make a lot of copies with my scanner and the person would then simple take my list source and fill in sellers info,  property address, stuff, address and stamp the letters before returning them to me. 

I am referring to direct marketing costs ( lists, stamps, envelopes, fulfillments etc.)

Well, William - the time stamp on this post is 7:02.  

I spend over $50 bi-weekly on stamps.Any advice of other way to marketing without spending so much money on stamps?

I didn't know you needed a stamp for local mail."
