There's no such thing as reliably predicting a crash - that's why it's called a crash. There's bulls and bears but no one side is 'right' in aggregate.
real estate doesn't really crash, like the stock market. It kind of... slides as liquidity dried up for higher price points. All of this takes many months, with many early leading indicators if you know where to look and have the right data
Holy wishful thinking batman. I don't know why you are fucking around with start ups, you should be on wall street
I'm describing data from '07-'10 across markets, not how I believe things might play out. Don't troll, show data otherwise.
