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

Great article! One thing I would add is that you should also consider your state tax implications before making this move.

The math checks out but I think you are being a bit conservative with the return assumptions. Historical averages suggest higher.
