REIN has no official studies on MB but I like Winnipeg for its low/no vacancy (I hate/fear vacancies), high-inmigration most of it international - have made offers there (have been told to steer clear of zones 9, 4A, 4B, 4C & 5A, 5B except for certain decent pockets in 4C , 5A, 5B). The fundamentals are there if you research & read things like the CMHC report on this CMA & it cash flows - we are nearly closing at $75k on a $700/mo. rent 2br & tenants pay all utilities there - but these are older homes & there`s rent control.
Market`s going wild though (houses selling in hours or over list in my preferred price range), and if u don`t get good cash flow from the bidding wars, go buy where u can get cash flow. For me, if certain numbers don`t match up, I`d rather stick to Southern Ontario where I live as I put a risk premium on a more distant city that I don`t know as well). WInnipeg has also one of highest crime rates in Canada. Other areas of MB may be better than Winnipeg but I don`t have the temperament & time to dig up research into smaller cities right now. Because of the royalty fees/increases in AB, many resource/mining companies are moving to SK & MB.
