My financial advisor recommended the exact same approach. Nice to see it validated with actual numbers.

Has anyone tried this with a single income household? We are a one-income family and wondering if the same principles apply.

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.
