Add over $20k to a home's value" is a bit misleading. That's just an estimate based on averages and local comps. The actual value it adds depends entirely on what a specific buyer is willing to pay.

Oh man, this is so true. A buddy of mine ignored a weird feeling about a shortcut home one night and ended up with a flat tire in a really bad spot. He says he knew it was wrong the second he turned. That gut feeling is no joke, the_val. He just sat there with the doors locked until a tow truck could get to him. It really changed how he makes those little choices now.

My last project used stone from three states over, so the truck basically had its own frequent flyer miles.
