Advice on funding the pay off of a lease to own property

[Rolando Frias]

I need advice on how to acquire funding to pay off a lease to own property. 

I am in the process of seeking out different options on how to get funding to pay the owner off and get the deed into my name.I owe the owner roughly 25K. Unfortunately I don't have that amount on hand in savings. The owner isn't troublesome, I just am ready to do other things with the property to help start my wife's and I venture into real estate investing. 

I contacted our lender on our current home but she stated that it would cost me a fortune for her to fund this amount as a conventional loan. I really felt she wasn't interested in working on it due to it being a small amount for a old home.

We do own another property that is free and clear. We planned to use that property early next year to help fund our first actual investment property. We feel we are finally at a point that we can commit to working on increasing our property porfolio for our future retirement.

Now my dilemma is that I have no clue what funding options I should seek out to pay this lease to own contract off and that would not put a road block in our plans of acquiring more properties next year?

I need advice before I make a wrong turn and put our plans on the sideline.
