My great-grandmother and her son, my grandfather each owned 50% of a house. They are both deceased. However,?

they are both deceased and the property is currently in the middle of two separate probate proceedings. My mother, who is the administrator and I would like to keep the property. We are now in the accounting stage of my grandpa's half. We owe $15,000 from court costs, etc. We are broke, but the house has only one loan of $11,000. As it's only half of the property, my attorney told us we could only obtain a hard money loan as my grandmother's half is ongoing. Could both halves of the estate be consolidated and paid back at the same time so that we could get a loan on 100% of the house?
