When my dad retired from the Air Force at age 49 they moved to Oklahoma City and spent a few weeks at my mom's moms house. Only long enough to find a house of their own. I teased dad about moving into his mother in laws house, but we both knew it was temporary.

They found a house owned by a retired Air Force officer. They wrote up a bill of sale, and shook hands. They went to the tax commission and paid the tax stamps, and had the deed changed. No real estate pros involved.
