HELOC using an Investment property as collateral?

[Gary Onstad]

I found a property I would like to purchase. I'm in the process of selling my home to fund owner occupy deals on multi family opportunities, but I'm not sure I will get to close of escrow in time to purchase the new place. I can't use my home as collateral on a HELOC while i'm selling it. Is it possible to get a quick HELOC loan using one or both of my investment properties as the collateral so I can have the down payment I need for the investment property? I think there is a lot of potential in this deal so I'm considering bringing in hard money or partners to fund it and rehab or add units. Any ideas are welcome.
