Looking for creative ideas

[Karen Ness]

We are currently trying to buy a property in North Dakota which will be an investment property for us, but my mother-in-law will be living there. Our problem is, we have identified a property to buy but we are right in the middle of construction on our new home and our lender has told us not to finance anything else until construction is completed. We have about 2-3 months until our home will be done but I don't believe this home in North Dakota will still be available if we wait. So, looking for creative ideas to finance the new home purchase in North Dakota. 

Open to all ideas.
