HELOC on Rental Properties

[Ryan McCook]

Are there any lenders that offer HELOCs on investment properties? I have 25 properties and would love to somehow use those as collateral for a HELOC - either multiple helocs, or ideally, just one larger line of credit.

However, all properties have mortgages on them with about 40% equity on average. I'm not interested in refinancing and pulling out cash as they are all locked with 30 year fixed rates, with very low interest. For me, I'm interested in HELOCs only.
