A few months ago, I saw a sale sign in front of my neighbor Gina’s house. She’s lived on my street even longer than I have, so I was surprised that she was selling her home. I bumped into her a week later at the supermarket and asked her where she was planning to move. She told me (with some regret) that she was downsizing to a less expensive house. The alimony payments she’d been getting from her ex-husband had ended last year, and she hadn’t prepared for the loss of that income. She soon realized she could no longer afford to live in her home.
