Using cross-collateralization as a method of down payment

[Ilya G.]

1. Hello,
2. I have several SFRs that have lots of equity in them and I wondering if anyone used a method of cross-collateralization to pledge the equity as collateral, thus avoiding doing a cash-out refinance or HELOC. It seems like a good strategy but would appreciate any advice and if anyone worked with banks/lenders that provide a service like that.
3. Thank you in advance!
