Rental Property Investment Advice!!

[Jake S.]

My friend (seriously) owns 1 paid for primary residence, and 2 rental properties in which his uncle acted as the banker for him on those properties (off the books)

So in the banks eyes, all 3 of his properties are fully paid for.

Primary residence is around $400k
Rental 1 is around $170k and Rental 2 is around $600k

He was thinking of taking out a LOC for the properties and reinvesting it to purchase a larger property, a property that would still cash flow well after LOC interest payment, P&I and budgeted expenses.

So I thought I'd ask on here for some advice on what YOU would do in his situation or how would you go about investing the available equity?

Would love to hear opinions and thoughts!!
