Hey there —

Say you decided last summer that Phoenix was overheated and you weren't buying into it. You'd have been right. A typical Phoenix home went from $454,692 to $447,054 over the following twelve months.

Here's what being right was worth. Twenty percent down, thirty-year fixed, rates at 6.72% then and 6.69% now: the payment goes from $2,352 to $2,305.

Forty-seven dollars a month.

That's calling the direction correctly and missing the magnitude by an order of magnitude, which is the most common way to be right in a way that doesn't help you. And here's the part that gets me — you'd still have no idea whether the plan was working, because nothing in it ever said what working would look like. Prices fell and you didn't buy. Had they risen the same 1.68%, you also wouldn't have bought. A position that produces the same action either way isn't responding to anything.

That's been the thread all week, and it showed up in three different disguises.

The median home price in a metro isn't the entry price — it's the midpoint of a distribution with a much cheaper band underneath it. "Wait for rates" has no exit condition — no number, no date, no branch for the case where the cut doesn't come. And the crash people are waiting for peaked last October and has been narrowing every month since December.

Same failure in all three: a number arrives from outside, it sounds authoritative, nobody asks what it measures, and then a real decision gets built on top of it.

One number this week. While everyone was watching the 30-year climb five straight weeks into early August, the bar we screen deals against moved too. The +5 Rule wants a cap rate at least five points over the 10-year Treasury — and the 10-year went from 4.48% in early July to 4.68%. So the green line rose from 9.48% to 9.68%. If you wrote "9.5%" on a sticky note in early July, you're screening against a number the market has already retired. (FRED DGS10, as of 2026-08-12. It moves — re-derive it the day you underwrite.)

A threshold isn't a constant. It's a function of things that move daily, and any rule worth using carries its inputs with it.

None of this is me telling you to buy. You might run the numbers and decide to keep waiting, and that's a completely legitimate answer — it's just a different animal when it comes with a price and a date attached. I walked through exactly that decision with three ways to play it, if you want the long version.

So here's my question, and I'd genuinely like to know: what's the number you're waiting on — and have you ever actually written it down?

Not "lower." A number, and a date. Hit reply. I read every one.
