</p>
<p>Sorry to be so long getting back. I had real work to do.</p>
<p>Implicit in your question are the following:</p>
<ol>
<li> All people live in major metro areas</li>
<li> All people buy houses for 20-30 years</li>
<li> Metro areas are homogeneous</li>
<li> Wealth gains from housing outstrip wealth gains from other investments</li>
<li> Past performance predicts future performance</li>
</ol>
<p>First, I don’t know where to find that data. But if I had to guess, I’d say one should look at Flint, Michigan, Rochester, NY, Muncie, IN, and Gary, IN for some possible housing value declines. All those places had major employers shut down or go through substantial layoffs.</p>
<p>But, to your issues.</p>
<ol>
<li> Not everyone lives in major metro areas, contrary to popular belief. The issue is about buying a house, not buying a house in Palo Alto. For instance, my parents bought a house in rurual Florida in the 60s on some land. They rented it out for less than the payments and got some income from selling their tobacco rights. When they got divorced, my mother called me home from college to go over the numbers, since that was far from her strong suit. What I found, going over the numbers, was that they had shelled out around $100,000, after income and tax benefits. They sold the property with $20,000 of equity in it. So, they might as well have set fire to that $80,000, not to mention the opportunity cost of not investing in, say, an S&P index fund.</li>
</ol>
<p>It’s true that out-migration from rural to urban areas has driven up housing costs in urban areas, overall, which simply means that buying a house in a rural area might be a bad idea.</p>
<ol>
<li> Which brings us to the next point, which is that all people don’t buy houses for 20-30 years. Houses are sold because of divorce, but I’d venture a guess that most houses are sold because someone lost a job. Often, jobs are lost because an employer closed down or had substantial layoffs. Naturally, a lot of families put their houses on the market just when no one is moving in because there are no jobs. And just as naturally, the housing market takes a steep nose dive. This happens in metro areas (especially in neighborhoods), small cities, and most especially rural areas.<br></li>
</ol>
<p>My wife has a friend who spent years trying to get rid of a house in Cosmopolis, WA after the bottom dropped out of the wood products industry for a while. She lost her shirt.</p>
<p>I also referenced Houston, where an acquaintance of mine bought a 6,000 square foot house around 1989 in the suburb where the astronauts live (can’t remember the name) for $190,000, complete with pool and helipad! But the guy who sold it to him had to bring a lot of money to the table just to unload it.</p>
<ol>
<li><p>Metro areas are not homogeneous. Some neighborhoods decay. Others gentrify. Often, there is not a good way to predict this. For instance, the Denny Regrade area in Seattle is now gentrified, but there are other parts of the city one might have thought would gentrify that haven’t done so. Neighborhoods can quickly deteriorate when an employer that drew heavily from the locality closes down, housing prices drop sharply, and many houses are abandoned or rented for songs.</p></li>
<li><p>Wealth generated from a house is often heavily leveraged, so a small percentage increase can be significant when compared to the initial investment or, for that matter, the total real cost. As I’ve said before, however, that works both ways. A 3% increase on a $200,000 house generates $6,000 in wealth, and a 3% decrease generates a $6,000 loss.</p></li>
</ol>
<p>But what if the difference between rental costs and buying costs had been invested in an S&P indexed fund at, say, 12% return (historically average)? The first house I bought cost me a net of $7,200 more per year than renting. That’s money I could have invested at 12% compounded yearly. It takes a fairly good return on a house to match that. I didn’t care. I wanted to own. But I didn’t go into the deal thinking it wasn’t possible to do better, elsewhere.</p>
<ol>
<li> As you know, past performance never predicts future performance. It’s not a bad place to look for trends, but assuming that a trend will continue into the future without doing some due dilligence is foolish. Looking at the long term, I’m not at all sure that we won’t see suburban houses lose value as energy/transporation costs increase. Someone buying a nice house in a suburb that tradionally has had increasing house prices might be in for a nasty surprise.</li>
</ol>
<p>Hey, I’ve owned four houses. I like owning a house. But that doesn’t mean that I think owning a house is the be all and end all of building wealth. For many people, that is probably not true.</p>
