Fed's "create" things by "making it rain" to create the actual producers to produce.

Real estate investments (STRs, MTRs, live in flips) have produced my best returns by a good margin.

The hedge funds and firms alone are buying more supply than is being produced. 

Consider selling the duplex to put it into a higher income producing asset (out of state, DST, something).

When the money dries up, they'll leave just as quickly as they arrived and you may be stuck with a real mess.If it can produce more money as a short-term rental, do it yourself.

@Mark Allen Hopefully, this gold mine is still producing.

SupplyLas Vegas is unique because it is a tiny island of privately owned land in an ocean of federal land.

in a few short years 1 property has produced over a $1/2 million in equity, thousands in cash flow, was leverage to buy another property which does the same and leverage to buy a small cash flowing business. 

How do you plan to build those tiny homes?

I self-manage and produce $700 in pure cash flow each month.Lessons learned?
