I am currently in Maryland (DMV region), which is very very tough for new investors using hard money to get in, and a friend had mentioned that NC would be a better area to consider and I do not mind relocating to NC if it is the right market for me.

I work on regional data projects quite a bit, and here are some links that will give you some sense of housing stock and growth projections.

I  came across few trophies and plaques in Toronto and its prices.
