Full disclosure: I am a newbie at all of this.

I a rental property that needs some attention.  It is currently occupied and the residents seem okay with the work being done.  

I do jot want to use any of my personal money, so I am thinking of tapping the equity. I also want to use this equityvto purchase another property.  

My question is: with rates about 2% higher on investment loans, (heloc and 2nd) should i just use my own residence to secure a loan or should I keep them completely seperate?
