I don’t think being young have anything to do with it. I’m 25, but I find myself explaining why there is a bubble to people much older than me. I see people who completely forgot about the last down turn. I think it has alot more to do with mindset than age.
One way for people to see there is a bubble, if they want to see it, is to just simply compare mortgage payment to rent. That alone will tell you price is not right. Why buy a 600k house when you can rent it for 2k/month while mortgage payment for an interest only loan is much higher than that. But the problem is, most people don’t want to see it. I talked some people buying recently but there are also other people that, even after I gave them reasons there is a bubble, they still buy anyways.
