What to Do When a Lead Actually Arrives
The response-time research everyone quotes, what it really found, and why the most repeated figure in real estate marketing is attributed to the wrong study.
Part of the Real Estate Lead Generation guide · Last reviewed 2026-08-09
Speed of response matters, and the numbers used to prove it are almost always misattributed. The claim that replying within five minutes makes you 100 times more likely to reach a lead comes from a 2007 Lead Response Management study run with InsideSales.com, a company that sold lead-response software, and the comparison is five minutes against thirty minutes rather than five against ten. Harvard Business Review's 2011 article is a different piece of research: it audited 2,241 companies, found 23% never responded at all, and reported that contacting within an hour made firms about seven times more likely to qualify a lead. Neither study included real estate.
Key takeaways
- The 100 times and 21 times figures come from the 2007 Lead Response Management report by James Oldroyd with InsideSales.com, not from Harvard Business Review.
- That study's comparison is 5 minutes versus 30 minutes. Between 5 and 10 minutes the reported drops are much smaller: about 5 times for contact and 4 times for qualification.
- HBR's own 2011 audit of 2,241 US companies found 37% responded within an hour, 24% took more than a day, and 23% never responded at all.
- HBR's separate analysis of 1.25 million leads found contacting within an hour made firms nearly 7 times more likely to qualify a lead than trying an hour later, and over 60 times more likely than waiting a day.
- Neither study covered real estate. HBR names financial services, automobiles, education, software, health care and professional services.
- The 2007 figures come from a company selling lead-response software, so they are attributable but not independent. The HBR company audit is the cleaner number.
The claim, and where it actually comes from
Almost every article about real estate lead response quotes a version of this: respond in five minutes and you are 100 times more likely to make contact and 21 times more likely to qualify the lead. It is usually credited to Harvard Business Review, and sometimes to MIT.
Both attributions are wrong, and the correction matters because a checkable claim on your own website is worth getting right.
Those two figures come from a 2007 Lead Response Management study led by James Oldroyd and conducted with InsideSales.com. The original report states that the odds of contacting a lead called in 5 minutes versus 30 minutes drop 100 times, and the odds of qualifying drop 21 times. The scope was three years of data across six companies, more than fifteen thousand leads and over one hundred thousand call attempts, drawn from InsideSales.com's own system.
The MIT attribution comes from Oldroyd having been a faculty fellow at MIT Sloan during that period. MIT did not publish the study, and the data came from a vendor's platform.
What Harvard Business Review actually reported
HBR published a short article in March 2011 called The Short Life of Online Sales Leads, by James Oldroyd, Kristina McElheran and David Elkington. It contains real and useful numbers, and they are not the ones usually quoted.
The first part audited 2,241 US companies by submitting a web-generated test lead and measuring the reply. 37% responded within an hour. 16% responded within one to 24 hours. 24% took more than 24 hours. And 23% never responded at all. Among companies that did respond within 30 days, the average response time was 42 hours.
The second part analysed 1.25 million leads across 29 business-to-consumer and 13 business-to-business companies. Firms that contacted a lead within an hour were nearly seven times more likely to qualify it, meaning have a meaningful conversation with a decision maker, than those trying an hour later, and more than sixty times more likely than firms waiting 24 hours or more.
So HBR's real finding is about the first hour, not the first five minutes, and the multiplier is roughly seven rather than one hundred. That is still a strong argument for responding fast. It is a different argument from the one being made in its name.
Why the distinction is worth making on your own site
There are three reasons to care about this beyond pedantry.
The first is that the 2007 figures were produced with a company selling software to speed up lead response. That does not make them false, and the underlying pattern is corroborated by the independent HBR audit. It does mean they come from a source with a commercial interest in the conclusion, which under any honest sourcing standard should be disclosed rather than laundered through a Harvard citation.
The second is scope. Neither study included real estate. HBR names financial services, automobiles, education, software, health care and professional services. The 2007 report's examples were insurance, automotive and lending. Applying a finding from software sales calls to a home purchase involves an assumption worth stating, because the decision timelines are not comparable.
The third is the comparison itself. The famous drop is measured from five minutes to thirty minutes. The same report shows the change between five and ten minutes is far smaller, roughly five times for contact and four times for qualification. That matters practically, because an agent who cannot answer in five minutes has not lost the near-hundredfold advantage the headline implies.
What to do with the finding, honestly stated
Strip out the misattributed numbers and the practical guidance survives intact, which is the useful part.
Respond quickly, ideally within the hour, because that is the window the independent evidence actually supports. The mechanism is not mysterious: a person who submitted a form is thinking about the topic right now, may have contacted others, and moves on quickly.
Respond at all, which sounds trivial until you note that 23% of the companies HBR tested never replied to a web enquiry. Failing to respond is more common than being slow.
Keep trying, since the 2007 data was built on over one hundred thousand call attempts against fifteen thousand leads, meaning multiple attempts per lead were normal rather than exceptional.
And match the channel. Someone who texted probably prefers a text back. Someone who submitted a detailed form may prefer a considered reply over an instant call from a number they do not recognise.
The part response speed cannot fix
Speed helps at one specific step, and it is worth being clear about which one, because fast response is often sold as a complete answer.
Responding quickly improves your chance of reaching someone who has just enquired. It does nothing about whether they were ever likely to hire you, and it does nothing about the look-up that happens either just before or just after your call.
This is where the rest of this hub connects. Given that NAR's data shows 57% of buyers choose an agent they already knew or were referred to, and 75% interview only one agent, most people arrive with a predisposition already formed. Answering in ninety seconds does not change what they find when they search your name.
The realistic order is to fix what someone finds when they check you, then respond fast to whoever contacts you. Doing the second without the first means arriving quickly at a conversation that was already decided.

Frequently asked questions
Is the five minute lead response rule true for real estate?
The five minute rule is based on real research, but neither underlying study included real estate. Harvard Business Review's 2011 article covered financial services, automobiles, education, software, health care and professional services, while the 2007 study behind the famous figures used insurance, automotive and lending examples. Fast response is still well supported as a principle, but no real-estate-specific version of the five minute finding exists.
Where does the 100 times more likely lead response statistic come from?
The 100 times figure comes from a 2007 Lead Response Management study led by James Oldroyd and conducted with InsideSales.com, which sold lead-response software. The report states that odds of contacting a lead called in 5 minutes versus 30 minutes drop 100 times, and odds of qualifying drop 21 times. It is not from Harvard Business Review, despite being credited there constantly, and MIT did not publish it either.
What did the Harvard Business Review lead response study actually find?
Harvard Business Review's March 2011 article audited 2,241 US companies with a test web enquiry and found 37% responded within an hour, 16% within one to 24 hours, 24% took over a day, and 23% never responded at all. A separate analysis of 1.25 million leads found firms contacting within an hour were nearly seven times more likely to qualify a lead than those trying an hour later.
How fast should a real estate agent respond to a lead?
Within the hour is the target the independent evidence supports. Harvard Business Review's analysis of 1.25 million leads found contacting within an hour made firms nearly seven times more likely to qualify a lead than trying an hour later, and over sixty times more likely than waiting a full day. Responding within five minutes is better still, but the difference between five and ten minutes is far smaller than headlines suggest.
Is responding in five minutes much better than responding in ten?
The difference between five and ten minutes is real but modest. The 2007 Lead Response Management report shows contact odds dropping about five times and qualification odds about four times between those two points, against the hundredfold and twentyfold drops reported for five minutes versus thirty minutes. An agent who cannot answer within five minutes has not forfeited the large advantage the headline figure implies.
Why should I be careful quoting the five minute rule on my website?
Because the usual version is checkable and wrong in three ways: it credits Harvard Business Review for figures from a different study, it states the comparison as five versus ten minutes when the source says five versus thirty, and it implies a real estate finding that neither study produced. Publishing a misattributed statistic on a site meant to establish your credibility works against the purpose of publishing it.
How many companies never respond to online enquiries at all?
23% of companies never responded, according to Harvard Business Review's audit of 2,241 US companies published in March 2011, which submitted a web-generated test lead and measured replies over 30 days. A further 24% took more than 24 hours. Among those responding within 30 days, average response time was 42 hours. Failing to respond at all is more common than responding slowly.
Should I call or text a new real estate lead?
Match the channel the person used, since it indicates their preference. Someone who sent a text usually expects a text back, while someone who submitted a detailed form may prefer a considered written reply to an immediate call from an unknown number. The 2007 study's data covered over one hundred thousand call attempts against roughly fifteen thousand leads, indicating that multiple attempts, not a single perfect one, is the normal pattern.
Can fast response make up for a weak website?
No, because they fail at different steps. Fast response improves your odds of reaching someone who just enquired. It does not change what that person finds when they search your name, which most people do before or shortly after the first conversation. With 75% of buyers interviewing only one agent, a look-up that raises doubt ends the process without producing any signal you can see.
Is the InsideSales study unreliable because a vendor produced it?
The study may well be sound, but it is not independent, and that distinction should be stated rather than hidden. The 2007 study was produced with InsideSales.com, which sold software for speeding up lead response, so the publisher had a commercial interest in the conclusion. Its broad finding is corroborated by Harvard Business Review's independent audit of 2,241 companies, which is the cleaner figure to rely on.
