I've read that currently governments in some countries are paying people to take mortgages, i.e. offering negative interest rates. The prices of property in those markets is probably so high that buyers are taking out interest-only loans that amount to renting, except they get all the rights/responsibilities and tax benefits of ownership.
Still, many people still don't want to own and be responsible for a mortgage, so those people are really just waiting for prices to come down, which signals overvaluation of real estate, which in itself signals cause for recession. in addition to stock markets being high.
The thing that's staving off correction at this point is volatility. The problem is that volatility generates a lot of short term profits, which stimulate spending if investors aren't very frugal with their 'winnings.'
If all the money being made on stock volatility would become frozen as long-term savings, that could cool the economy and prevent, or at least soften, a correction; but whenever I think the economy could become tempered by tightening of liberal consumer behavior and the economic/development activities that accompany it, my expectations are contradicted by widespread growth and development activities.
As a result, I expect a correction to occur at some point as markets become oversaturated with new developments and price overvaluation.
