Does a hot market actually mean good cash flow? I tested it and honestly, no

There's a shorthand a lot of us use without noticing: fast market equals good market.

Homes go under contract in days, buyers are lined up, and somewhere in there "this market

is hot" quietly becomes "this market will cash flow." Those are two different things. One

is how fast the market clears, the other is how much rent a dollar of price buys you. So I

put them side by side across 672 metros at current data, using mean days to pending as the

heat measure and gross rental yield as the cash-flow proxy.

The relationship is real but weak. The fastest fifth of metros, going pending around 29

days on average, yields about 5.84 percent; the slowest fifth, around 96 days, yields about

6.56 percent. That is the whole spread, roughly 0.72 of a point. The correlation is about

plus 0.21 and the rank version agrees, so it is not outliers, but an r that small means

heat explains only something like 3 to 6 percent of the variation in yield. So heat is a

poor predictor of cash flow. You cannot read one off the other.

This cut against my own prior. I expected a strong negative link and it came back weak. And

sort by heat instead of speed and the yield gradient is not even monotone, the lowest

average yield sits in the second-hottest bucket, not the hottest.

Here is the useful part, and it is easiest to see by naming names. The hottest markets in

the country do not share a yield, they split. Rochester New York goes pending in 15 days

and yields 6.72 percent. Syracuse, 22 days, yields 7.40 percent. Buffalo, 24 days, 6.01

percent. All three are as hot as anything in the country and all three cash flow. Now San

Francisco, 29 days, every bit as hot on the demand side, yields 3.40 percent. Same heat,

four full points of yield between Syracuse and SF. Heat put them in the same bucket and had

nothing to say about which ones would feed you.

Go the other way, to the highest-yield markets, and it skews slow and cold as you would

expect, small Deep South and Plains metros where homes sit: Meridian Mississippi around 13

percent at 71 days, Woodward Oklahoma near 12 at 109 days, Big Spring Texas around 10.7 at

115 days. But it is not clean either. Danville Illinois goes pending in 34 days, genuinely

fast, and still yields 10.75 percent. Charleston West Virginia is fast, hot, and yields

10.2. Speed does not cleanly sort this list in either direction. I am naming both the

fast-and-fat and the fast-and-thin markets on purpose, because this is a description of how

price and demand are distributed across these metros, not a buy list.

One caveat I will put on the table myself: yield has price in the denominator, and a hot

market bids price up, so part of this is arithmetic. True, and I am not hiding it. But if it

were purely mechanical the hottest markets would all be yield-poor, and Syracuse and Buffalo

show they are not. The mechanical piece is real but not the whole engine.

Limits, up front. This is 672 metros with both a usable absorption reading and a usable

rent-to-value pairing; about 250 drop out for lack of a clean rent index and skew small, so

the set leans larger and more rentable. It is a single snapshot, so no claim that speed

predicts future yield, only that at any moment the two barely track. I checked that the

pattern holds back to 2019, weakest right at the 2022 peak when everything ran hot at once.

And days to pending is a seller-side clearing-speed measure, not a statement about the

people who rent in these places.

What I am chewing on, and would like your read on: have you caught yourself using a market

being hot as a stand-in for it cash-flowing, and did it ever burn you? And when you find a

fast market that also cash-flows, like a Syracuse or a Danville, do you treat the speed as a

bonus or get suspicious that you are missing why it is cheap?
