Neighborhood that you wouldn't consider investing in?

[Dan C]

How would you describe a neighborhood that you wouldn't consider investing in? I live in a small to medium size Canadian city with a few not so great areas, but have some great deals from disgruntled landlords and/or foreclosures that I would love to take advantage of, but everyone I talk to tells me to stay away from these areas, granted they aren't landlords and really have no idea about the rental business. I'm also guessing the majority of the rentals in these areas are rented to, what the US would call section 8 tenants.
