Help. My husband and I are building a new house. We are a blended family and we need more space. I have two boys ages 10 and 12 that live with us full time. Their father passed away 4 years ago. My husband has three children but two of them are adults ages 23 and 21. The youngest is 17 and he visits a us every other weekend and two weeks in the Summer. He will be going to college next year and more than likely living on campus.
