It is going to cost you if you want to get out and into the market again. I think some people do have regrets about doing that in previous downturns,even though on paper they were losing and would continue to lose in the near future. Hopefully people who have experienced exactly that will respond.That is probably going to be your situation,as you know.Anyway crunching the numbers specific to you house and situation to understand your own risk/reward scenario is key. I think whether you feel you have a safety net that you don’t mind using, or not, should be the deciding factor if you just can’t make up your mind.
