If I was at my house when it started, I would get a couple kitchen knives. If I have a chainsaw and lots of zombies come, I'll be slower because a chainsaw is heavier than knives. If there weren't that many zombies outside, I would try to get to the car and drive away (I would bring my pets and family with me, of course.) If there were lots of zombies outside, I might try and hide in the attic.
