Very rarely somebody says "I've decided I want to sell my home." On the rare occasion when they decide to sell a home, it's because there's been a lifestyle change.
Somebody's had a major health event. Maybe they had a stroke and it broke a hip. So I'm sitting in your living room because you had a lifestyle changing event and do you really want to wait for that?
What we tell people is "Make the decision now, you don't have to do it now. Decide what you're going to do when and if something happens." Because it's the 'when' is the question mark. The 'if' shouldn't be the question mark.
So you need to make the decision now, and frankly, it's a gift to your children. More importantly, It's a gift to yourself. You make the decision now on what you want to do, where you want to go, how you want to go.
