Every coaching deck in real estate has the same slide: respond to an online lead within five minutes and you are dramatically more likely to convert it, with impressive multipliers attached and Harvard's name underneath. It is one of the most repeated statistics in the industry. So it is worth asking a simple question about it. Is it true?
What can actually be verified
The article is real. The Short Life of Online Sales Leads, by James B. Oldroyd, Kristina McElheran and David Elkington, was published in Harvard Business Review in March 2011. Its publicly visible summary says this: most companies are not responding nearly fast enough.
That is the verifiable claim. The full article sits behind a paywall, which means the overwhelming majority of people repeating its statistics have never read it. And the specific multipliers that travel with the citation, the ones about being some large factor more likely to make contact at five minutes than at thirty, appear to originate in a separate and older dataset produced with vendor involvement, then to have been attached to the Harvard name in retelling.
I could not verify those multipliers in the primary source, so this post will not repeat them as fact. That is not pedantry. A number nobody has checked, quoted by everyone, in an industry that sells urgency, is exactly the kind of claim that deserves the scrutiny.
The advice survives without the numbers
Here is what makes the statistic unnecessary: the mechanism is observable in your own business.
An online enquiry rarely reaches only you. Portal enquiries are often distributed to several agents, and people researching independently usually contact more than one. So the reply is a contest, and the first useful answer does something the second cannot. It frames the conversation, sets the terms, and quite frequently ends the search altogether, because the person's goal was to get an answer and stop looking.
Nobody needs a multiplier to believe that. You have been on the other side of it, choosing the contractor who called back.
Speed matters differently depending on the lead
The blanket rule is where most agents waste effort. Not all leads are contested in the same way.
Portal and paid leads are the most contested, frequently shared, and almost purely a speed contest. Here, minutes genuinely matter, and a considered reply that arrives fourth is worth very little.
Your own website enquiries usually arrive with intent about you specifically. They came because of your content, your reviews, or a recommendation. You are typically racing the person's attention rather than three other agents, so a thoughtful reply within a couple of hours generally outperforms an instant, generic one.
Referrals are the least contested of all, and per NAR's 2025 data reported by Virginia REALTORS, 43% of buyers found their agent through a referral. These people already have your name. Frantic speed here reads slightly oddly; reliability reads better.
Sorting your urgency this way is more useful than a universal five-minute rule, because it puts your fastest response where the competition actually is.
Fast and empty loses to specific
A reply that arrives in ninety seconds saying "Hi, thanks for reaching out, when can we talk?" has spent its speed advantage and bought nothing. The next agent who answers the actual question becomes the helpful one, and helpfulness beats being first.
The useful first reply does two things: answers what was asked, at least partially, and proposes one concrete next step. If someone asked about a specific building, say something true about that building. That is harder to systematise than a template, which is precisely why it works.
Being fast without living on your phone
Permanent availability is not a strategy, it is a countdown to worse service. What works is deciding in advance what deserves interruption.
Notifications on for the contested categories only: form submissions and calls. Everything else routed into two or three deliberate clearing sessions a day. The aim is a reliable maximum wait rather than an impressive best case, because consistency is what your response time actually is, and your median is what clients experience.
Automatic acknowledgements have a narrow, legitimate role here: they buy time honestly when they sound like an acknowledgement and state when a real reply will come. They damage trust when they imitate you personally and then leave silence behind, because the person believes they have already reached a human.
Measure yours before you fix it
Most agents overestimate their response time considerably, because the memorable cases are the ones where they answered immediately.
For one month, log two timestamps for every enquiry: when it arrived, and when a real reply went out. Not an auto-reply, a real one. Then look at the median rather than the average, since one holiday week will distort an average completely.
Compare that spread against which enquiries turned into conversations. This is a small, boring dataset from your own business, and it will tell you more about your conversion problem than any industry statistic, because it is actually about you. If the enquiries themselves are the problem rather than your speed, our post on traffic without calls covers the other end of the pipe.
Why the window has narrowed
One genuine change worth noting. The person contacting you today has usually already done their comparing somewhere you cannot see, across several tabs or inside an AI chat that summarised their options. They arrive nearer a decision than enquirers did a few years ago, as we described in how leads arrive from AI search.
That compresses the window in which your reply is still relevant to the decision they are making. Not because of a multiplier, but because the research phase moved earlier and out of sight, leaving the contact moment carrying more weight than it used to.
The second contact matters more than most agents think
Speed wins the opening. What loses the client afterwards is the gap that follows it.
The common pattern: a fast, good first reply, then nothing for four days, then a message asking whether they are still looking. From the other side, that reads as someone who was keen until they were not, which is worse than a slower start would have been.
Two things prevent it. Decide the next step before ending the first contact, out loud, so the follow-up is expected rather than intrusive: I will send you those three listings tonight and check back Thursday. And make more attempts than feels natural if they go quiet, spread across days and channels, because a missed call proves nothing about intent. Most agents stop after two tries and conclude the lead was junk, when the person was simply at work.
There is a limit, obviously. Somewhere past a couple of weeks with no response at all, persistence becomes noise. But the failure that costs real business is almost always the opposite one, and it is invisible, because nobody writes to tell you they went with the agent who kept in touch.
The takeaway
The five-minute statistic is repeated far more often than it is checked, and its usual attribution does not hold up to a look at the primary source. Treat it as folklore. Then act on the mechanism anyway, because the mechanism is real: contested enquiries are won by the first useful answer, and your own logs will prove it faster than any study. Sort your urgency by how contested each lead type is, make the first reply substantive rather than merely quick, and measure your median for a month before deciding you already respond fast.
