Property and pessimist theories

[Mark Wolk]

Some say that the current financial situation may evolve into a crisis similar to that of 1929. So, how did mum and dad property investors come out of the 1929 crisis?

I suppose they had a hard time for several years, whilst their tenants did not pay their rent, and then... what happened with the value of their properties?

I suppose also that those who bought properties during the crisis made a fortune with them when the crisis was over. Is that correct?

Anything that can be extrapolated from the past into the future?
