Our savings rate is around 35% including taxes. Approximately 12% goes to 401K, 8% goes to Roth and the remaining 15% goes to a fund to buy real estate. We occasionally increase the 401K contributions to avoid going from the 15% to 25% tax bracket.
We plan on buying house #3 within 12-18 months. I think the end goal is to be 50% stocks and 50% real estate which includes around 3-5 properties.
