If you could sell the houses for 800k each, subtracting the debt means you've got about that much in equity on the two put together. If the 15k you make from them is the total income, that's a pretty lousy rate of return, under 2%. If that's a profit above and beyond the mortgage payment and you are hacking away significantly at the principal each year, that would be better. Again, we need a little more clarity.
To be totally honest, and I don't mean this as an insult, but for the kind of advice you're looking for I'm wonder if this is really the right forum. The classically "mustachian" thing to do would be to retire right now, sell the almost million dollar house, the ski condo, and the guns, invest all that cash you have sitting in the bank, and figure out a way to live a rewarding, enjoyable life in a smaller house, using the investment income and rents you have coming in. That way you don't have to worry about how health care reform is going to affect your income. I know that's not the kind of advice you're looking for but I can't help suggesting it.
