There seems to be a misunderstanding.
The five signatures are required for obtaining a Concealed Carry Permit. At one time the requirement was for the five to be from your zip code or voting district, I really do not recall which. Nowadays it is five from your county.
The two property owners signatures were for you to purchase a handgun.

In 1991, when I got my DE CCP, it was 5 "registered voters, from your voting district".
I remember this because 1 of my first 5 was NOT a registered voter (how he didn't know that I'll never understand), and 2 were not in my voting district as it (the district) went thru my development a few houses down from me.
What a PITA it was, having to go in and confirm each of the 5, before submitting my application.
