If it's different this time... then, well... GREAT! That means these bidding wars will continue, homes will keep selling for well over listing, and my properties and overall investment portfolio will keep increasing in value. :)
If not, well, then trouble could be brewing if you're ill-prepared...
I'm not smart enough to figure out what will impact what causing what, but I do believe in cycles and what goes up usually comes back down again...
If an investor got in at an opportune time (like you did @J. Martin), chances are you loaded up and acquired a bunch of assets during the ripe-for-the-picking peak recovery period between 2009-2012... But even in 2013, 2014 it wasn't too late and good deals were still pretty plentiful... The last deal I closed was earlier this year, when I finally went ahead and said, "NO MORE!"
Could this thing keep inflating? Sure, it could... But I look at it from a risk/reward angle -- Trying to leverage more and winning "one last deal" can end up being the straw that breaks the camel's back.
When it comes down to it, it's fueled by greed... In the Bay Area, even if you only won a SINGLE house during the recovery, you're still coming out miles ahead and that SINGLE property has probably appreciated by a minimum $100,000...
Why keep pushing your luck? I'd rather preserve what I've got and stash cash from this point on (I completed two cash out refis recently to pull equity out for the next round!); I'm ok with missing out on whatever deals remain in 2015, 2016, 2017, etc., should this bubble keep expanding.
I'm happy with the progress I made this round (ain't contentment a wonderful thing???); now I just wanna live to fight another day...
