Dear Dave: My wife and I make a little over $50,000 a year combined, and we’re almost debt-free. Right now, we have $50,000 left on our mortgage and $4,000 in student loans left to pay. We’re both really excited about the future, and we’re thinking about selling our home and moving into a trailer her parents own. On top of this, we’d like to save my wife’s entire salary for five years to buy another, better house. What do you think of this plan?
