Personally, I think urban inner-city real estate is much more secure than suburban (with some local-specific exception). So your inner city examples, given proximity to downtown, and being single-family, would probably be safer bets then those looking further afield.

I also think that there's more international speculation than just China, although agreed, they have been a major driver as of late.

One factor to keep an eye on, is vacancy rates. I've heard mixed messages, but from what I see, there aren't nearly as many empty condos as many people assume there are.
