Pay down or Scale up

[Shrikkanth Parthasarathy]

All, 

I'm a newbie. House hacking does not work for my situation. I still have a mortgage on my primary home, and recently acquired a rental in a smaller cheaper market. I might come into money. My internal debate is whether to first pay off my primary mortgage, get to a point where I am living mortgage free, or should I buy more and continue to work. 

Any thoughts and inputs will be highly appreciated..

Thanks!
