No one can decide for you, for a while I lived in a neighborhood where the guy with the shotgun in the shower would NOT have been paranoid.
I don't like the idea of stashing myself. Unless you want to keep several identical guns in various places in the house and can be sure that no one will find them I think it is a liability. If the threat level is that high, I want a full size service sidearm, backup sidearm, reloads, flashlight and designer kevlar on my body 24/7! And only until the moving van gets here.
I keep one up and one downstairs ready to rock, both under "accessable" lock and key. BUT I also live in a town of 900, across the street from the city building and I know my neighbors.
If I were in a city of any size, I might consider carrying on my own property but I would not stash guns with the hope I would be in the right place to grab it if I needed it. Too iffy.
