So the Tax advantages and building equity are worthless and play no part in peoples desire to buy instead of rent. Ok
I'd also argue that most other assets are also highly inflated. The P/E on most tech stocks for instance looks a lot scarier than the overall real estate market. I'll add that people have been saying the Bay Area housing bubble will pop for over 30 years. It hasn't yet.
There is a huge lobby in society to convince you that owning a home is the way to go (banks, real estate agent, other homeowners and people repeating this nonsense all the time). Don't let this fool you and make the calculations before buying anything.
