Even if there is some overlap in buying/selling houses, you will be fine in the end. We went through all that a few times. The last time was the hardest since we had to move ourselves and finance the new house before the old one sold. Don’t worry… it will sell! People still need housing, and there always seems to be a shortage. Hopefully everything will fall into place, but even if it doesn’t all go smoothly, it will in the end!
