How can I raise $50K to finance my first deal?

[Ryan Lauritsen]

So I found a duplex I would like to purchase. I have the cash, but it is tied up for other purposes that I can not use right now. I would really hate to pass up this investment. The down payment would be about $50K. So my question is what are some creative financing that I could do to come up with the money? My credit is fine and should have no problem getting approved for a conventional home loan.
