Leveraging portfolio equity

[Jonathan New]

My portfolio is now at 17 properties, and I am looking into the possibility of tapping into some of the $608k equity that I have built into these deals.  They are already leveraged at 75-80% however, so therein lies the rub.  Is liquidation the only option, or are there lenders/PM partners who would lend with the remaining equity as collateral?   I believe that I know the answer, but if such a lender or partner exists, this place knows about them.
