At some point in my life, I’ve dreamed about living in a gigantic mansion in some exotic location where the ocean breeze lightly blows against some beautiful Egyptian cotton curtains. I’d bet that most of us have that dream at some point—and perhaps some of us are already creating a path to get there some way, somehow. Want more articles like this?

Let’s start with that small, two-bedroom condo. Oh, wait. We need more space! We need a three-bedroom townhouse. But then we really want a yard—and this kitchen is too small. And where’s the “man cave”? Plus, our kids need a room. Pretty soon, we are trading up from that tiny apartment to a gigantic house or from a neighborhood where you are a bit scared to walk at night to that subdivision with the really good schools. It’s the American dream, isn’t it? But sometimes you have to consider the cost of trading up your residence. I know two couples who live in Orange County, Calif., who after living there maybe a couple of years, are already looking to trade up to a new home that costs nearly double what their previous residence is worth (i.e., $350,000 to the $800,000 range). Sure, it is in a much better neighborhood. Sure, sometimes you need that extra office and nurseryâbut consider the cost! Even at 4 percent, your monthly payment will have gone from $1,337 to $3,055 (assuming you put 20 percent down each time, and this is a 30-year fixed loan)! That is a lot of changeâno matter what you do. Related: Should I Pay Off Debt or Use Those Funds to Invest? What About Building Net Worth? Sure, you can build equity faster every month with the bigger house, but that is because you are putting that much more money into it. You are tying up cash into a house that you have to live in. Whether the housing market goes up or down, you are tied to living in that residence. It is also an extremely illiquid investment. While you think you can sell a house quickly today, that’s not always the case in a given market. Your entire net worth has become dependent on what the next person is willing to pay for your home. It is an extremely volatile and risky investment if you tie up most of your wealth into a house. “The Market is Going Up. I Can Sell to Buy a Better House!” Can you? If you only own that one house, is it worth it for you to sell that home to buy another one? In a rising market, all houses go up in value. If you are trying to buy a similar or better house, wouldn’t it cost you more money even though you sold your house for more money? What difference would it make? And another thing: Every time you trade up a house, you are paying a lot of expenses. I have flipped properties before, and I know selling costs can sometimes range from 8 to 10 percent of the actual selling price. It is a huge transaction cost. Those real estate agents are waiting for those big bucks—bucks that you don’t have to spend if you decide not to sell your property and go buy another one. Imagine selling a $350,000 house and having to spend $30,000 for transaction fees. That’s the price of a car! Related: Are Extra Mortgage Payments Worth It? A Look at the Numbers If You Have to Trade Up, Trade Up Wisely All I am saying is that it may not necessarily be wise to trade up for a bigger place until you are truly financially ready. Sometimes living in that two-bedroom condo will give you an opportunity to save a lot of your wealth for other investments. Or maybe you could live small and trade up really big further down the line instead of constantly switching. I’ve heard that the average time Americans live in a residence is seven years. Maybe the next time you switch up, you should wait 15 to 20 years. It is a long wait, and you may not like your old home so much. But hey, the rewards for saving now can benefit you greatly in the future. What do you think? Leave your comments below!
