Today I am going buy more stamps , envelopes, and legal pad.So I write more letters every free moment I get.

I figure that the few bucks for paper, envelopes and stamps could be worth it. 

PoL is negotiating with this person to save their shirt on another of his delinquent deals!

What service did you use to print stamps onto envelopes?

@Spencer Trotman,You may want to re-think your approach.Why not just drop them a hand-written letter in a hand-written envelope with a 1st Class stamp stating your interest in buying a home in their neighborhood and asking if they know of any that might be for sale?

It is a pre-manufactured, and much "beefier" (Lower left photo) support system designed to provide additional vertical and horizontal resistance in wind, snow, and seismic zones for which the design criteria has been pre-approved and stamped by an engineer.

They can do this cheaper than I can because they can get discounts of buying stamps in bulk (2million at a time), and I do not have the resources to do that on that large of a scale.

The shirt and right newer is yes.  

I have a tenant on food stamps who was at the social security office and saw me at the property when she got back.

Gently serve copies of said time stamped legal documents to your "tenant" and respectfully ask for the arrears.
