We have to move/Need to rant for a sec

Yesterday we got a call from my husband's aunt telling us that we're probably gonna have to move, due to her mother in law (who owns our house) and sister in law up and deciding they want her to move back in. We've helped put a lot of work into this house while we've been here and it was talked about letting us start doing payments so we could buy the house but that all is out the window now. We know that when she moves back into the house every bit of work we put into fixing it is going to go down the drain because she's the one who destroyed it in the first place and refused to have any actual (and much needed) work done to it. We don't have any family we could stay with, and I'm due in less than a week with our 2nd baby and our daughter who will be 2 by the end of the year hasn't stayed anywhere else, this is home to her, we may have to rehome our cats, and I'm just overall really upset that this is happening. I got my hopes up thinking we finally have a place to call home and have a family after moving around multiple times and then this happens.. We have at least 3 months to find a new place to go.. And I dont even know where to begin to look for a new place on top of having a baby on the way...
