You can trade vol just in different areas, real estate isn't one unless you're deep with money. 

Bitcoin ETFs are up 38%. 

We have discussed selling the property and rolling it into a multi-family but again feel like we may be trading a fairly hands off property with good cash flow for one that may be a bit more labor intensive and only yield marginally better performance.Any advice on how to expand our rental portfolio/maximize its performance is greatly appreciated!   

Another path to consider is to sell them under a 1031 exchange and trade into higher-value real estate.

I don't have any career worthy trade skills or college degree, so finding a higher income job is slim pickins for me.

Not sure if you need to think about budget or not, but downtown will be very very expensive.I don't think there are enough lots that trade that there would be any time of accurate or even ballpark pricing.I don't know anything about it, but there does seem to be some good demand in self storage parking and also in truck parking. 

But the income from the STR far surpasses that of the LTR, so it's a trade off.
