Oh come on, that’s being extremely, EXTREMELY… I can’t find the word. Not pedantic, not pessimistic, and not near sighted. Whatever the term is for when you take the absolute extreme edge case to try making a point.
Rent will always go up over time due to inflation. Yes, you might have dips for a year or two, but landlords will always raise the rent based on inflation at the minimum. And regardless of big drops in house prices during economy crashes, your mortgage does not go up over time outside of adjustments to taxes and insurance. Even when there was the worst housing crash in US history in 2008, my rent never dropped. My rent kept going up every single year by the maximum amount the city allowed under rent control. Housing prices dropped, which allowed me to buy a house. And in your case where you talk about losing $360k due to buying instead of renting over 10 years, you are ignoring that $245k will be going to buying down the principle (amortization calculations for a 6% loan on $1.5M for 30 years). You spent $552,000 at a bare minimum, assuming no rent increases (impossibly unlikely), and have 0 to show for it. The owner spent almost exactly twice that but has $245k in equity on top of whatever equity had grown from house prince inflation over 10 years. Every year it gets better for the homeowner, especially when you hit 30 years and have paid off the house… while you are still renting.
In reality, when I bought my house 12 years ago my mortgage was $3900 (with taxes and insurance) and rent would have been $4000. Now, my mortgage is $4100 and rent is $6000.
Now, I’m also ignoring the money that can be made investing the money you save renting vs buying. But if we use your assumptions, then there is no guarantee you’ll make money investing your money.
Just fine, because I kept it for longer than the recommended time that good mortgage brokers tell you to plan for evening out costs and riding out dips. It would have cost me an extra $300k to buy it before the crash, plus the four years it took to recover from the crash before prices started climbing again. In the four years that housing prices were dropping (2008 to 2012), my rent went up, not down. Sure it didn’t go up very much in those 4 years, but it didn’t stay flat like my mortgage would have (I don’t know if the property tax went down during the time due to assessments dropping, but I don’t think they did). And I wasn’t paying down principle like on the mortgage. Yeah, my house value would have only doubled in 10 years instead of tripled, which only means I wouldn’t have been able to leverage the equity to buy a vacation property that I still haven’t built on.
Also, remember that the stock market ALSO crashed during that time. It took nearly 5 years for the stock market to recover from the 2008 crash.
Finally, the guy who tried flipping it just before the crash made some questionable decisions on what changes to make for his flip, some of which I have had to undo. If he had just kept the house as it was and lived here instead of trying to be a flipper making a profit, he would have been fine after 5 years. But since I owned it instead of renting, I was able to change the house as I saw fit to be happier living in it.
