... was a couple years back ..
and that is useful in today's low oil and NDP days why ?
AB is retracting to a normal province with a left-leaning overspending government, with lower oil prices for longer, thus with reduced investments, in a world where oil and gas is systemically assaulted with carbon taxes, pipeline opposition, electric car technology and global warming / climate change policies bordering on extremes, with an overpaid civil servants apparatus (25-30%), growing deficits and now ex-migration. Why is this a good place to invest in the next 2-3 years until the painful retraction to a "new normal" is over ?
House rental rates in AB are 10-25% lower than a year ago in many places, or if they are not, they will be once your current tenant leaves. As such, Devon is as good or as bad a place as any to own a house. I see no reason why it would be any worse or any better than say St. Albert or Sherwood Park or Edmonton. The nearby mall at the airport might help.
If you think you can cash-flow a place with realistic rents, then yes you should buy as you will make money even in a flat or slightly declining market. But as I said earlier, I'd wait as Edmonton and area has not yet seen the drop Calgary has experienced in 2015, and with layoffs to come in the biggest employment sector in AB, construction, Edmonton's drop so far has been very muted but will get worse this year and next. As such, wait to 2018.
