Keep it. You’ve got a good rate, you like the house, and you’re planning on coming back.
To come out ahead, selling, the following needs to be true.
1. housing has to fall significantly both in real terms and nominally. I think this will happen, however, you need more than a 35% fall before you get to breakeven on selling costs and original price. That’s getting steep.
2. Rates have to fall another full percentage point after they’ve already fallen 1%.
3. You have to actually get it sold if you want to sell.
4. What you buy when you come back has to be in comparable shape to what you have today. I don’t think that’s likely.
