One can blame Airbnb, Zillow or whoever else, but the truth is that speculation in real estate and vacation towns have both been a thing for a very long time. If the population rises and we refuse to build more houses, the existing ones will get more expensive no matter what. The solution is out there in front of us but everyone prefers to dance around it.
> If the population rises and we refuse to build more houses Building more houses is generally good too, but it's a bit of a cop-out to blame the whole situation on that. Totally independent of supply concerns, I would argue that it's not great that in so many areas the value of homes seems to be almost entirely divorced from the fact that people need homes to live in . Imagine if a bunch of very wealthy people just…
Additionally it kind of strains belief that people are buying homes, paying property tax, etc. just because they like collecting them the way a kid likes collecting pokemon cards. More likely they'd buy a home because they expect home prices to rise and they'll be able to sell the home for more in the future. It may be unintuitive, but if your market is not incredibly supply-constrained this is actually a good thing.
Here's why. Let's say there's an up-and-coming college town, and speculators think that in a few years the town will become trendy and many people will want to move there. If they're right, demand will go up and home prices will rise. That means you can buy a home now on the cheap and sell it in a couple years when houses are more expensive to make a profit. But of course, when you buy a house now, you're contributing to demand for houses, so you're making the price rise in the present in response to a change in demand you anticipate happening years from now. Since home prices are rising, it now becomes more profitable for people to build new homes. (Their costs haven't changed, but now they can sell the homes to speculators who are willing to pay a lot because they expect to sell the homes to the people who'll move in as the town becomes trendier.) So what you get is people building homes now in preparation for people wanting to move here years from now. Making homes available will cause home prices to go down, until the market is at equilibrium and homebuilders are no longer willing to build homes for the price that homebuyers are expected to be willing to pay.
So in theory it all works out quite nicely. In practice, people who own the homes hate this because they like that the home they bought for $200k in the 90s is worth $2M now, so the lobby to get local governments to ban people from building homes. If there were enough homes that everyone who wanted to live there could, the prices of housing would come crashing down and homeowners would lose the bag they worked so hard to get (not).
