I've heard that banks don't like to give you 30 year notes if you already have 5 or more existing notes.  8% COC return isn't bad for most people who want conservative and less volatile investments. 

There is much more volatility and seasonality in it.3.

Appreciation is a very market specific topic that I am sure we can write essays about and it is more volatile than returns from rent.

The longer your hand stays in the pot with these, the more volatile they become.

I had to sell some of my investments stocks, Rentals, ... because of the high volatility in 2017.

A lot of big rental property investors much more intelligent than I right now are looking closely at the midwest and south for high yield properties in less volatile markets that probably won't crash as hard as major cities will in the event of a correction in nationwide property values.I looked at @Tim Herman's list.

@Ryan Weimer there should not be that kind of volatility in the rents and those numbers don't even make sense. 

Within your Roth you could get more conservative with stocks and add in bonds or other low volatility investments and cash. 

However, on the macro level, Canada as a whole isn't very strong right now and there is tons of volatility.

If you look at stock market volatility, I'd say this week we are starting down that path.
