The only thing I'd worry about on your detailed plan is waiting till a certain year to start selling your real estate, and then needing to sell on a regular basis for income. Real Estate is so variable that I'd be keeping an eye on the markets and selling places when it's a good market, and not when you need the money.
Very good point and you're absolutely right! My thought was keeping a year or two cash reserves in a short term CD or something similar just for those occasions when the timing isn't right for selling a home or maybe if we go through another dip in the market and I may not want to touch the money in my IRA for a couple of years to allow it to possibly build back up. That is the problem with relying on investments when retiring early. Don't want to keep it in too safe of a investment vehicle because will miss out on some good growth but obviously can be nerve wracking in too aggressive of an investment. I have a lot of research and thought to put in before I take the plunge. Thanks for you input!
