Hey there —

Forty-eight basis points in five weeks.

That's how fast the 30-year mortgage rate moved — from 5.98% on February 26 to 6.46% by April 2, then a small pullback to 6.37% as of last Thursday. FRED publishes the number every week. If you weren't watching the weekly print, you might have missed that a buyer who locked at 5.98% in late February now needs roughly $5,000 to $7,000 more annual income to qualify for the same house at 6.37%. Same house. Same down payment. Different month.

I've been thinking about what Ray Dalio would say about this.

His new book Principles — which we reviewed this week — has a line that stuck with me: "I believe that the biggest problem that humanity faces is an ego sensitivity to finding out whether one is right or wrong and identifying what one's strengths and weaknesses are." The real estate version of that sentence: most investors can't admit when the math just changed.

The math just changed. Not dramatically. Not catastrophically. But enough that a deal that worked at 5.98% might not work at 6.37%. And the investors who pretend the rate didn't move — because they locked mentally at the number they saw when they started shopping — are the ones who'll overpay this spring.

Here's the concrete version of that statement. We published a county-by-county deal breakdown this week that shows the same Kansas City metro producing a $30,348 annual cash flow gap between two counties — Caldwell County at $278/month positive and Johnson County at $986/month negative. Same renter, same rent, same rate environment. The difference is entirely in the cost structure underneath the county line. The rate shock makes the gap wider, not narrower.

Meanwhile, the labor market is telling a story the headline number hides. We found 51 metros where unemployment jumped a full percentage point year-over-year — and 22 of them are in Florida. The same Florida metros where home values are declining and rents are flipping negative. Three federal data sources, all flashing the same signal.

So what do you do with a 48-basis-point move?

You don't panic. You sharpen. Pull the county-level data for your target metro. Stress-test your deal at 6.46%, not 5.98%. Check the unemployment trend before you check the cap rate. And if the math works at the higher rate with the real expense stack — not the broker's gross proxy — then the deal works regardless of where rates go next.

Dalio would call that "radical transparency with yourself." I'd call it underwriting discipline.

What's the one deal you passed on in the last 30 days — and does it still pencil at 6.37%? Hit reply. I read every one.
