So long story short my fiance and I are financially struggling and my inlaws have graciously opened up their home to us , we will have our own room however we are also moving in to help them pay for a basement remodel which will eventually be our living area. But construction hasn’t started and I would be uncomfortable if we lived there for a year or two before it finished after we agreed to help them pay for it. My concern at the moment is my inlaws believe we will be there for the rest of our lives as once they pass the house will be ours anyway. So I want to have a baby before 30 and I don’t see us moving out in the next 7 years. Any advice?
