Sound decisions about what real estate to buy, own, or rent are important at any life stage, but especially when you're in your 40s and 50s. The benefits, costs, and emotional characteristics of real estate make it different than any other type of investment. Whether you upsize or downsize your home, buy a vacation property, or gift a down payment to help your kids get settled, the decisions you make about property now will have an important effect on your retirement plans, nest egg, and future lifestyle.
