It's much easier to set-up a trigger-free home environment if living alone or with another very compatible person. (For some people, living alone may serve as a trigger.)
Be very mindful of the neighborhood: the noise, the nearby interstate highways and/or truck routes, the police reports. When I used to hunt for apartments, I'd check the address with the police and was almost always shocked with the police reports; this method saved me a ton of money and stress.
I need to give this a bit more thought.
A great question, by the way!
