These 2 Variables Dictate the Financial Wisdom of Homeownership

Often times, we forget what a big difference small changes can make.

For much of the past century, the financial wisdom of buying and owning your own home was unquestioned. It was considered far and away the best investment one could make with his or her money.

And then the Great Recession came along and left in its path a wake of foreclosed homes and families with plunging net worth. The knee-jerk reaction was quick and decisive: Buying a home as an investment suddenly made no sense at all.

I personally added to that commentary a little more than two years ago, coming down on the side of renting. But life situations change -- my wife and I are once again pondering buying a house after moving our family to a smaller community to settle down.

Our primary considerations have little to do with money. As I'll show below, for the fiscally disciplined, I still don't believe homeownership provides the financial windfall many believe it does. Rather, we simply want to be able to make the home our own, remodeling or building as we see fit, and we also want the social benefits that come with establishing yourself within a community.

The fact that those reasons -- in our opinion -- don't usher in financial rewards is just fine with us. What's money for anyway, if not to help you live the life you want?

That being said, there are countless people buying homes to live in for the investment, rather than the soft variables, and for many of them, that's a mistake.

A quick look at both sides
The value of homeownership is one of those topics that can cause normally mild-mannered folks to jump up and down with indignation. Luckily, some of the brightest minds here at The Motley Fool can disagree and still remain friends.

No one has spent more time talking about the perils of homeownership than Morgan Housel. You can click the link to read his full argument, but it all basically boils down to this: Homes are fabricated goods, and as they improve, the one you own will become outdated and accordingly devalued. On the whole, expecting the price of your home to do more than keep pace with inflation is dangerous.

Morgan also pointed out  that many will end up owning a home for 10 years or less and that during that time, all they've really done is pay off a large sum of interest to the bank because of how amortization schedules work. What's the difference between that and paying rent?

On the other end of the spectrum we have Anand Chokkavelu. He penned a piece talking about why buying usually wins. While he concedes many of Morgan's points, he points out that, given the financial behaviors of many people, buying is better because it incurs forced savings via equity.

Though we might save money by renting, he notes, "I think a greater percentage of us than we'd like to admit end up blowing the money anyway." That's a fair point, and one that matches up with reality for many people.

As a simple matter of fact, however, my wife and I have spent the better part of the last four years figuring out what "enough" is for us. We're quasi-minimalists, and any money we might make beyond our "enough" simply gets put away in retirement, college or -- more recently -- down-payment funds.

The two variables that make all the difference
If you're in our situation, how can you determine whether it makes financial sense to buy a home? One of the tools I come back to over and over again is a nifty calculator designed by The New York Times. It takes 21 different variables into account before letting you know how the dollars and cents all play out.

Let's say I want to buy a $200,000 house, which is about the median price for existing U.S. homes right now. Let's also say I'm renting a house that's almost identical. Though it varies wildly by city, let's say that the price-to-rent ratio where I live is 19, which is the current average among 54 major U.S. metropolitan areas. That means I'm paying about $880 per month.

Using the default function of the calculator, I see that if I buy the house and live in it for six years, it's a better financial decision to buy.

But there are two default settings that I find to be highly misleading. The first is the assumption that home prices will increase by 3% per year, while inflation will push a 2.3% pace. Historically, the spread between the two is much thinner: 0.2%.

By changing my home's appreciation to 2.5%, I find that I now need to live in the house for nine years before it makes financial sense to buy instead of rent.

Another issue is that the calculator assumes your down payment will be invested and will return about 4% per year. But that flies in the face of the market's historical compounded annual growth rate of 9% (since 1871).

Even if you don't believe consistent 9% returns are possible anymore, you'd have to average below 6.2% returns in order for buying to make financial sense after living in your home for 40 years. That's significantly lower than what the market has historically yielded. 

Seeing the trees for the forest
You can play with the calculator all you want to see how your own situation would play out. And, of course, there are a lot of real-life variables to consider that have nothing to do with money. That's why I said from the beginning that my wife and I are considering buying even though we believe it to be the financially inferior choice.

Everyone has their own situation, but the numbers don't lie. If the century's worth of data we have is any indication, buying a house should almost always be a lifestyle decision over a financial one.

To be perfectly clear, this is not a get-rich action that my Foolish colleagues and I came up with. But we wouldn't argue with the approach.

A 2015 Business Insider article titled, "11 websites to bookmark if you want to get rich" rated The Motley Fool as the #1 place online to get smarter about investing.

"The Motley Fool aims to build a strong investment community, which it does by providing a variety of resources: the website, books, a newspaper column, a radio [show], and [newsletters]," wrote (the clearly insightful and talented) money reporter Kathleen Elkins. "This site has something for every type of investor, from basic lessons for beginners to investing commentary on mutual funds, stock sectors, and value for the more advanced."

Our mission at The Motley Fool is to help the world invest better, so it's nice to receive that kind of recognition. It lets us know we're doing our job.

Whether that's helping the entirely uninitiated overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we want to provide our readers with a boost to the next step on their journey to financial independence.

Articles and beyond

As Business Insider wrote, there are a number of resources available from the Fool for investors of all levels and styles.

In addition to the dozens of free articles we publish every day on our website, I want to highlight two must-see spots in your tour of

For the beginning investor

Investing can seem like a Big Deal to those who have yet to buy their first stock. Many investment professionals try to infuse the conversation with jargon in order to deter individual investors from tackling it on their own (and to justify their often sky-high fees).

But the individual investor can beat the market. The real secret to investing is that it doesn't take tons of money, endless hours, or super-secret formulas that only experts possess.

That's why we created a best-selling guide that walks investors-to-be through everything they need to know to get started. And because we're so dedicated to our mission, we've made that available for free.

If you're just starting out (or want to help out someone who is), go to, drop in your email address, and you'll be able to instantly access the quick-read guide ... for free.

For the listener

Whether it's on the stationary exercise bike or during my daily commute, I spend a lot of time going nowhere. But I've found a way to make that time benefit me.

The Motley Fool offers five podcasts that I refer to as "binge-worthy financial information."

Motley Fool Money features a team of our analysts discussing the week's top business and investing stories, interviews, and an inside look at the stocks on our radar. It's also featured on several dozen radio stations across the country.

The hosts of Motley Fool Answers challenge the conventional wisdom on life's biggest financial issues to reveal what you really need to know to make smart money moves.

David Gardner, co-founder of The Motley Fool, is among the most respected and trusted sources on investing. And he's the host of Rule Breaker Investing, in which he shares his insights into today's most innovative and disruptive companies ... and how to profit from them.

Market Foolery is our daily look at stocks in the news, as well as the top business and investing stories.

And Industry Focus offers a deeper dive into a specific industry and the stories making headlines. Healthcare, technology, energy, consumer goods, and other industries take turns in the spotlight.

They're all informative, entertaining, and eminently listenable ... and I don't say that simply because the hosts all sit within a Nerf-gun shot of my desk. Rule Breaker Investing and Answers contain timeless advice, so you might want to go back to the beginning with those. The other three take their cues from the market, so you'll want to listen to the most recent first. All are available at
