Blanket Loan scenario?

[Ken Eck]

I am looking at creative financing options (low to no- money down). I am trying to scale my protfolio, limit my mortgages  and trying to not lock up much liquid captial into DPs so I have been reading up on Blanket Loans and had a question form in my head.  

I have a property that has 30% (I know not a lot but hear me out) equity and I was wondering if it was possible to refi this existing property into the a blanket loan and bring what ever the difference would be, if any, in cash to keep the loan at a 70% LTV level?

Is it feasible or should I drop it and move on.
