I don't want to throw it into a volatile stock market.

However, with the current stock market volatility, this might be a good time to stick it in an index fund :)@Erik Sherburne couldn't agree more.  

Unless you have something locked, they could be blowing smoke in mirrors and/or the market can change daily (sometimes even mid-day if it's very volatile).  

@Alex CorralAs @Bill F.. mentioned, it definitely depends on your personal goals and risk tolerance, but on a straight comparison:2-4 Unit MF rentals are valued on a comparison basis so the equity appreciation or deprecation will be more volatile. 

The volatility index has been astonishingly low.

I had brought a game camera but the magistrate told us she wanted us and her to leave as the situation was volatile (she had already been in some heated verbal exchanges with a "sister" of the occupant that was trying to remove items that were "hers").

I'm a builder in Oklahoma, we have seen our share of booms and busts… The oil and gas industry is extremely volatile.

We provide wholesale properties to investors as well as hard money but I do caution my investors to stay up to date on where the Houston market goes due to oil volatility.  

I have contacts and investments in a particular business model in Australia, returning ~20% net (downside being exposure to a somewhat volatile currency) plus capital gains.The model involves the rights to manage hotels/ vacation apartment rentals/resorts.

Obviously this experience helped me to understand why people struggle here all the time with identifying high volatility and fluctuation on prices.
