They got a crime page somewhere that shows the incidences in each neighborhood. I would stay well away from anywhere East of the airport, places like Falconridge, Taradale, Martindale, Castleridge, Whitehorn, Rundle etc etc etc.
Mayland Heights would be alright, I guess...but Id have to do a little research in that neighborhood. Like driving by and seeing who lives there, how many rental places there are, looking at their yards, cars, how many liquor stores, bars, porn and pawn shops their are. Looking at conditions of roofs, siding etc. Same deal in Dover, Dover seems alright. Ogden seems alright.
Anywhere in the NW is good to go in my books. Cheaper area would be like Bowness.
The SW is all good. The SE is different when you get into Forest Lawn thats why I always double think Dover because of its proximity to F.L.
I've always been peeking in on MLS, I am want to buy a rental property. You can find some great deals all around the city. Some places go for $320 in the SW. I would stay well away from Condos unless you are retired because of the condo fee and the repair costs that can and do go aove the reserve that you will ave to pay.
