BRRR strategy and the market

[Mike Shahi]

So what happens when the market tanks and the house you refinanced for $250k is now valued at $180k? 2008 anyone? 

Do you just continue to hold, rent and hope for the best? 

For the people who BRRR'd in 2004, 2005 etc etc up until the market took a turn- how did you deal with the crash? Advice please
