.: Hello,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.

These properties can often be acquired through creative financing methods like:Seller Financing: Negotiate flexible terms with motivated sellers who want to avoid traditional bank processes.Lease Options/Subject-To Financing: Take over a seller’s mortgage without assuming full responsibility, especially for properties needing renovation.Creative Terms: Adjust terms to fit market conditions, like offering lower down payments or longer payoff periods.Staying connected with investors and tailoring deals to current conditions can help you secure opportunities even in challenging markets.
