First, I will add another vote to "don't assume a 7% return" camp. Others already mentioned inflation, 7% average over 20 yrs vs needing 7% every year, etc. But just as much as economics, consider a requirement to move every year or every few months. People, especially as they get older, tend to like knowing they have a home where they can spend as long as they want, where they know their neighbors, etc. It might not feel like a big thing until one loses it. Personally, I would consider downsizing and if needed do occasional work for travel money. My 2c.
