I do know what you are feeling. We went from a three-story condo on Lake Michigan to having a wall behind us and a house in front of us.
But do know that if you end up not liking the lifestyle (which I doubt), you have made a non-risky investment that you will not lose money on if you decide to move on. You'll just have to pack again!
Good luck on the sale of your home. Don't forget to bury a statue of St. Joseph upside-down in your yard. Works like a charm.
