The buyer implication

A house that's $50K cheaper but 5 extra miles from every kid activity can cost $24,000 MORE over a 10-year hold.

That's a real example, math available in the calculator. The "cheaper" house is often the more expensive house. Buyers don't see that until they've lived it. Sellers don't market it. You can.
