The risks you spend the most time talking about are usually not the ones costing you the most. Here is how the gap opens. A pipe bursts in the middle of the night and floods three units. It makes a mess, it makes the local paper, and it makes for a very bad week. By the following month the operation has been reorganized around it. There is a new water-shutoff protocol, a new inspection added to every turn, a line item for leak sensors, and a standing agenda slot where the flood keeps coming up long after the last unit is dry.

None of that is wrong. A flood is worth preventing. But look at what did not change in the same month. The maintenance requests that sat four days too long, the handful of tenants who quietly did not renew because of it, the collections that slipped a little on three properties, the same small turnover churn that has been running in the background for years. Those got no new protocol, no line item, no agenda slot, because none of them flooded anything or made the paper. And between them, over the year, they cost far more than the flood did.

You Are Prepared For The Disaster That Already Happened

This is one of the most reliable ways human judgment goes wrong, and it has a name. In the 1970s the psychologists Amos Tversky and Daniel Kahneman described what they called the availability heuristic: when we judge how likely or how frequent something is, we do not actually count. We reach for how easily an example comes to mind. If instances spring up quickly, we treat the thing as common and dangerous. If they do not, we treat it as rare and safe.

Most of the time this shortcut works, because common things do come to mind more often. It breaks in a specific way: when something is memorable for reasons that have nothing to do with how often it happens. A flood is memorable because it is sudden and dramatic, so it lodges in memory and feels like a live threat for months. A maintenance ticket sitting a few days too long is not, so it never feels like a threat at all, no matter how many times it happens. The mind files risk by how loud it was, not by how much it cost.

What Memorable And What Costly Have To Do With Each Other, Which Is Nothing

The cleanest demonstration of this is a little morbid. Researchers once asked people to estimate how many Americans die each year from various causes, and the answers were wrong in a consistent direction. Dramatic, heavily reported causes like tornadoes and plane crashes were overestimated. Quiet, common ones like stroke and asthma were underestimated. A follow-up found the errors tracked almost perfectly with how often each cause appeared in the newspapers, not how often it actually killed anyone. People were not estimating frequency at all. They were estimating memorability.

At work, the newspaper is whatever your operation was just talking about. The flood, the owner who blew up on a call, the one bad review that traveled. Those events become the operation's headlines, and the headlines set the agenda, whether or not they represent where the money is actually going.

The Boring Risks Are Where The Money Actually Leaks

Here is the asymmetry that makes this expensive. Property portfolios almost never bleed from one spectacular event. They bleed from thousands of ordinary ones, each too small to seem urgent, that add up quietly across a year while the dramatic incident gets all the meetings.

The flood cost you a bad week and a repair bill, once. The maintenance delays that shave a few points off renewal at three properties cost you turnover, vacancy, and make-ready, every single month. One of those is a story everyone remembers. The other is a line on a report nobody reads. But if you added them up, the forgettable one would be several times larger, and it would be the one you did nothing about, precisely because it never gave you a moment dramatic enough to react to. You end every year thoroughly protected against the last vivid disaster and fully exposed to the ordinary ones that are actually draining you.

The Correction Is To Count Instead Of Remember

The fix is not more willpower or a better memory, because the bias lives in memory itself. The fix is to stop letting memory allocate your attention and let the numbers do it instead. The right question is never which risk feels most pressing, because feeling is exactly what is broken here. The right question is which risks, added up over the year, actually cost the most, and that is something you answer by counting, not by recalling.

The problem is rarely that the information does not exist. It is that it lives in pieces. The maintenance delay sits in one report, the slipped collections in another, the avoidable move-outs somewhere else, so each one looks small in isolation and none of them ever adds up in front of you. The single instance is all you ever see, and the single instance is never memorable enough to act on. When the operational history sits in one place, as it does in RIOO, those scattered small events finally sum into a pattern: the unremarkable four-day maintenance lag, multiplied by how often it happens, turns out to have cost more this year than the flood everyone still talks about. That total is the thing memory can never show you, because no single piece of it was ever worth remembering.

Judge Risk By The Bill, Not By The Memory

None of this means ignore the flood. Rare disasters are real, and some are worth real money to prevent. It means stop letting the drama of a risk decide how much attention it gets, because drama and cost are not the same thing and are often barely related. The most dangerous risks in a property operation are rarely the ones that make a good story. They are the small, dull, repetitive ones that never earn a meeting, because each instance is too minor to remember and the total is too spread out to feel.

So when the next vivid incident reorganizes everyone's priorities, it is worth asking a quiet, deflating question before you follow: is this actually where the money goes, or is it just where the memory is? The risks that cost you the most are usually the ones too boring to remember. Which is exactly why you have to count them, because you will never feel them coming.

FAQ

1. What is the availability heuristic?
It is a mental shortcut, identified by Amos Tversky and Daniel Kahneman in 1973, for judging how likely or frequent something is by how easily an example comes to mind. It usually works, because common events are recalled more often, but it produces systematic errors when an event is memorable for reasons unrelated to its frequency, such as drama or media coverage.

2. How does the availability heuristic distort property risk decisions?
It makes vivid, recent incidents feel more important than they are, so a dramatic event like a flood or a lawsuit captures attention and budget, while frequent but unmemorable risks get ignored. The result is an operation heavily defended against the last dramatic event and exposed to the ordinary ones that quietly cost more.

3. Why do boring risks often cost more than dramatic ones?
Because dramatic risks tend to be rare and large, while boring risks tend to be frequent and small, and frequent-and-small usually wins when you sum it across a portfolio over a year. A one-time flood is a single bill; a routine maintenance delay that erodes renewals happens continuously, so its total can be several times larger while never feeling urgent.

4. How do I stop over-reacting to the last big incident?
Replace memory with counting. Instead of asking which risk feels most pressing, add up which risks actually cost the most over the year using your own records. That means tracking the frequent, low-drama events, maintenance lags, slipped collections, avoidable move-outs, so their cumulative cost becomes visible and can be compared to the dramatic one everyone remembers.

5. Does this mean I should ignore rare disasters?
No. Rare disasters are real and some are worth serious money to prevent. The point is not to ignore them but to stop letting a risk's drama decide how much attention it gets. Prevent the flood, but do not let it crowd out the dull, repetitive risks that, added together, are quietly costing you more.
