I was thinking about this some more and i thought of something i really like
beach houses, particularly the ones on slits, if you disable one of the entries you can control the zombies access to your house, get more creative and you could even have a draw bridge.
you could grab a golf cart, those run on electric and would be a good way to get around town without making too much noise.
plus its a well know fact that zombies cannot swim, so you could leave a boat anchored not far off that you could swim too should things ever get extra ridiculous
