Paying off current Mortgage or invest in new rental?

[Jedd Storoshenko]

I currently live in what will become a rental property and vehicle for retirement. I am contemplating whether or not to buy another property that cash flows in a high priced market or payoff the mortgage of the property where I currently live in and want to rent out. I max out 401k, IRA, and HSA contributions. I carry no debt other than current mortgage on property I live.
