Help! I made a newbie mistake!

[Sarah Hood]

I made a cash offer on a duplex in another state ( Grand Rapids, MI), it's an off market deal and I had to act fast. I misjudged how long it would take to get through my re-finance on my house, and my loan officer said I would not have the money in time.  I had started the process before making the offer and only moved forward when she said she had found an underwriter, which I thought meant I was in the clear, but it doesn't. The property is 195k, I have 125, so I am needing a 70k bridge loan, in a week. Is that a thing? 

Is there a loan product in the world that can help me? 

This is not my first deal, but my first that includes financing and I have never borrowed from a bank before. I have 2 other properties besides my home, and it's my home that I am financing to fund this duplex. So I am sitting on a heap of equity, I have a very low reportable income, which is (I think) what is making this thing take so long. I spent a lot of time studying deals and I am confident this is a good one. I know that leverage is the way to grow my real estate business, but I didn't think to study the loan industry and its products and processes.  

Any advice appreciated!
