I am in a "mixed" marriage.
I have lived in 3 houses and 1 condo in my nearly 66 years.
My wife is an Air Force brat, lived in 2 countries, 3 states and best she can recall 16 houses by the time she was 10. Thanks to her parents divorce, and her mom remarrying a couple of times, she lived in another 12 houses by the time she was 18.
Two different life experiences but one thing we decided on before getting married was we were going to stay put, moving was too big a hassle. We rented for the first 9 months when we got were married to save up a down payment, bought our house 40 years ago and expected it would be our last residence, and so far it has been.
