Asking "where to invest" is as nuanced as asking "what car to buy" or "what do you like to eat" .. as it is highly individual, depends on one's appetite for risk, one's ability to write a sizable cheque, one's ability to spend time researching an area, one's desire to spend even more time managing an asset impeccably once acquired etc ..
To make money in real estate you have to know a SMALL area of a city with upside very very well, and then specialize in an asset type, as one cannot be an expert in THs, SFHs, multi-family, mobile home parks, commercial office towers, retail strip malls, land development or ocean front acreages although all of them allow plenty of upside (or downside if done poorly).
As such, a better question to ask, for example in Edmonton is: I have $105,000 to invest and I am thinking to buy an up-down house in BonnieDoon (close to the new LRT) or in Millwoods (also close to the new LRT). Which one is better ? Or: will Calgary be better than Red Deer ? Or: AB is recovering. is it too early to buy now, better wait a year ?
