Hi namaste 🙏 to all ! Can you guys help me to make the best decisions please.....I currently have one primary house to live and one rental unit. Both of my property have 40-50% equity. The income from my  unit breaks even after the mortgage and condo fee. But I been paying almost $1300/month just in interest on my primary residence. Both property were refinanced last year with (4%) interest rate.  

Now, my question for you are as follows.

1) Should I sale my rental ( condo ) unit and pay off my residential property ( by doing this I might be saving lots of interest that I been paying every month plus market are still good ) ?

2) Keeping the rental and residential. But Cash out  from one of the property and buy another property?

3) sale the condo and buy a multi family house little in cheaper area and rent it out ?

Please please help me !
