Street Rates vs. Achieved Rates: Why Each Number Lies Alone

Two operators can describe the same facility honestly and give you opposite pictures. One says rates are up 30%. The other says revenue per square foot is down. Both are telling the truth. They are quoting different numbers, and the gap between those numbers is where most storage underwriting mistakes live.

Street rate is the advertised price for a vacant unit today — the number on the sign, the website, the aggregator listing. It is a marginal price. It applies to exactly one transaction: the next move-in.

Web rate is the online-only version of the same thing, typically discounted below the walk-in street rate to win the search click. In most markets it runs 10% to 20% below street.

Achieved or realized rate is what the existing tenant base is actually paying, blended across everyone in the building — long-tenured tenants who have absorbed several rate increases, recent move-ins on promotional pricing, and everyone in between. Public Storage reports this as realized annual rental income per occupied square foot. In its second quarter of 2026 that figure was $21.89, down 0.8% from $22.06 a year earlier, while occupancy rose to 92.5% from 92.3%.

Why they diverge. Street rates are volatile and seasonal, because they are set weekly by revenue management systems responding to unit-type availability. Achieved rates are sticky, because they are the accumulated residue of every pricing decision made over the past three years. When street rates crash, achieved rates barely move for a year — the existing tenants are still on their old rates. When street rates recover, achieved rates lag again for the same reason, in reverse.

This produces the single most common misread in the business: an operator sees street rates up 30% off the trough and concludes the market has recovered. It has not. It has recovered for new move-ins. What the operator collects next year depends on how many tenants roll, how many existing tenants absorb an increase without leaving, and what the move-out rate does when those increases land.

The bridge between them is ECRI. Existing customer rate increases — the periodic bumps sent to tenants already in place — are what pull achieved rate toward street rate over time. The economics are unforgiving and simple: a rate increase that raises revenue 8% but lifts move-outs enough to cost 6% of occupancy is nearly a wash, and it burns tenant goodwill you cannot re-buy. A facility with a big gap between street and achieved rate has room to push. A facility where achieved rate already exceeds current street rate has an exposure problem, because any tenant who checks a competitor website has a reason to leave.

That inversion — achieved above street — is the condition to look for in a soft market, and it is why occupancy can hold at 92% while revenue falls. The building is full of people paying yesterday price, and every replacement tenant comes in cheaper than the one who left. Public Storage second quarter is a clean illustration: occupancy up 20 basis points, realized rent down 0.8%, same-store revenue down 0.6%, same-store NOI down 2.2% as costs rose 4.3%.

What to do with this when underwriting. Three rules.

First, never underwrite a purchase on street rate. Street rate tells you the ceiling for new business in the current month. Underwrite on achieved rate and be explicit about how fast you think the gap closes.

Second, always ask for the rate roll — the distribution of what tenants are paying by tenure. A facility at 90% occupancy where the average tenant has been in place four years and is 25% below street rate is a very different asset from one at 90% where everyone moved in last quarter at promotional pricing. Same occupancy, same street rate, completely different forward revenue.

Third, watch web rate as the honest signal. Because it is set to win the click, the web rate is the least flattering and most current read on what the market will actually bear. When web rates rise, demand is genuinely firming. When street rates rise and web rates do not, someone is posting a number they do not expect to collect.

The discipline is holding all three in view at once. Street rate is the market opinion. Web rate is the market revealed behavior. Achieved rate is your bank account. Only one of those pays the debt service.
