The 2 avenues always seem to be do it now it's not getting any cheaper, and just wait it out things will come down soon enough. I don't think there's any one good answer anyways. IMO the answer you get depends on if you sign the front of a check, or the back. Personally, and I sign the back of my check, I'm going to wait for any huge purchase.
We want to build a house on some property we bought a year ago, that would also include drilling a well. We haven't done anything to get the ball rolling yet with the hope that material prices will become more affordable as whatever it is were in right now evolves. "They" say housing is slowing down but there are still what seems like a million new homes under construction around these parts, so the truth is housing hasn't slowed down at all, the price of existing single family homes may have slid down a bit but construction is still going strong. That in itself is enough to keep materials and labor healthy.
I used to think I made good money at my job but when I see how much less I can buy here lately it makes me want to quit and learn a new trade, I "have" been wanting to open up a tropical fish store...
