I guess they aren’t used to stamps haha.

It's a cost of the sale, just like your closing attorney, title company, tax stamps, etc. 

The notice to quit cites the KRS code and was hand delivered by me to her door where I taped it to her door and took several photos with date and time stamps.

It's basically a stamp of approval that the county followed all of the instructions and the deed was transferred properly.

A stamp costs $0.49 for first class, I think $0.34 for a postcard.

That's odd, I never sent out one yellow letter, the only stamps I bought were for verifications mailed out, then got a meter, never ran a TV, radio or newspaper ad, but they talked to me in interviews.

One good thing about the forms is they are automatically dated and time stamped.

All I had to do was file the Writ of Execution form and have the court clerk stamp it once it was filed. 

These would be stamped by a structural engineer.

One thing I am going to try next time is I heard you can hire a architect engineer firm and when they finish the city will pass their plans with no changes, as it as a stamp from the engineer.
