Cheapest option to obtain financing for bidding in cash

[David Kosiorek]

Hi All, 

I currently have 3 properties  (purchased and partially rehabbed with cash-260k) and I'm not sure how to best bridge the gap in cash between now and I assume about 75 days or so (Expect to sell one of my rehabs, the other two like need another 3 weeks before they are finished).  I'm sitting on about 25k cash but for me to continue to bid on more houses im thinking i need another 50-75k.  Which I'm not sure ill even be able to purchase another property before i close so id like to have access to the money but not necessarily need it unless any of my bids are.accepted.  

What are some of my options?

Thanks
