The people in this thread who are building are doing so because they can. You know the costs (or have ridden out the cost hikes along the way), but said eff it, are enduring the pain and getting it done. Why? You have the money and will to do it. You are likely secure in your job and are well-versed in the risks you are taking. You are not the average American right now.
You are also invested in this housing market big-time, and might not like hearing what I am saying because it may mean you will soon own a house that you "overpaid" for, which you were hoping would not be the case. Even though I purchased from inventory, I have the same concern. But that's a price you were willing to pay (and I was as well), you wanted this for your family and you plan to be in the house for decades, if not the rest of your life. You accepted the risk.
I can't predict the future, I'm just telling you my opinion based on what I am seeing. Understand I am not predicting that the housing market will crash. At worst, I think the housing market could pull back maybe 5 percent by this time next year. but beyond the housing market, I see an economic downturn which will affect people not in this thread a hell of a lot more than the people in this thread. People who don't own houses and aren't secure in their employment and are already paying out the @ss for an apartment and are getting pummeled by high gas and grocery prices. Those are the people who are about to feel the pain.
