I'll leave out the moralistic component. When it comes to value, some other considerations are the low interest rates we experience, the fixed 30-year loan, in the U.S. that is, and interest tax deductions. So one isn't pummeling 1M in investment that could otherwise go into a business. One is putting in 200k, even less with an FHA loan, and deducting the price of the loan.
Now we get more advanced. Buy a multi-family property, and you get rental income. This rental income is balanced against depreciation of the house, so your personal income bracket isn't affected. When you combine the tax credits, the low cost of loans, the increasing rents, the principal you're getting back, when the dust has settled you're light years ahead of those folks who rented and pumped their money into some seesaw investment vehicle like the stock market.
I pay out of pocket less than the price of a studio, and own a standalone house in one of the country's top three rental markets.
It gets better, because you can sell the property to purchase another, and defer all tax payments on the profit of the sale. 1031 exchange.
As someone else said, it's pointless to generalize nationally. We live in a big country, assuming you are US-based. I bet there's a similar dynamic in the UK or Canada, both of which have noises of a bubble.
