IMHO -
1) Down markets come every 8-12 years. 2000-2008-xxxx? The story I got out of this past recession was that it was a very slow (unusual) recovery and therefore the 8-12 year cycle should be more on the longer side.
2) Seems like we are agree that when interest rates start to creep up that it will lead to a downturn in markets. I'm sure the government knows this and they are going to put some mitigation in place so this does not happen to a great extent. They have said they were going to raise raise since 2012 but we are still in the holding pattern.
3) BP has grown to 300k users... is this a good thing or a bad thing. We can't be all RE investors.
4) I want to point out that there is a paradime difference in people who are investing in their own homes (& living in the cyclical East/West coasts) and those investing for cashflow with rentals. If you are investing in Cash Flowing Rental (w/ 50% rule) who cares if we are near a bubble.
