(they are typically buying for the long run since that is where they are going to live so they might not really case as much about the cyclical market neither).Yes, you can get into a flip just when the market crashes and you are screwed but you might not be able to predict that  time anyway so my advice is to move as fast as you can and do as many flips as you can while it lasts to save up some cash for when the market is down, then start getting a great deals.I think the worst thing is to keep waiting..
