There is a specific piece of research that most real estate coaching content references without actually reading. It is usually shortened to "respond within 5 minutes," repeated in a webinar slide, and left at that. The original study is worth understanding properly, because the actual data is more useful, and more alarming for anyone running an agency, than the shorthand version suggests.
What the Five-Minute Rule Actually Proved
In 2007, Dr. James Oldroyd, working with InsideSales.com, ran what became known as the Lead Response Management Study, analyzing sales leads across multiple industries to measure exactly how response speed affects outcomes. The finding that made the study famous: agents who called a lead within 5 minutes of it arriving were 21 times more likely to qualify that lead than agents who waited 30 minutes. The same research found a 100 times higher likelihood of even making contact at all within that 5-minute window versus waiting half an hour.
Separately, Velocify, a sales acceleration platform later folded into ICE Mortgage Technology, analyzed roughly 3.5 million leads on its own platform and found that calling within 1 minute of a lead arriving increased conversion rates by 391% compared to waiting 2 minutes or longer. This is vendor platform data rather than independent academic research, and it's worth being clear about that distinction. But the sample size is large, the methodology has been consistently described the same way across multiple citations, and the direction of the finding matches the MIT research closely enough that treating it as directionally reliable is reasonable.
Why the Comparison Point Matters
Notice what both studies actually measured: not "fast versus slow," but specific minute-by-minute windows, each showing a steep, non-linear drop-off. The decline in a lead's willingness to engage is not gradual. It behaves more like a cliff than a slope, with most of the damage happening in the first several minutes after the lead is created.
Why We Recommend a 90-Second Target
Here is where we want to be transparent about something: 90 seconds is not a number from an external study. We have not found a published benchmark that names 90 seconds specifically as a meaningful threshold, and we are not going to imply that one exists.
What we do know, from the research above, is that the documented advantage is concentrated inside the first 5 minutes, with the sharpest gains appearing inside the first 1 minute. A 90-second target sits comfortably inside both windows, while giving a real, automated system enough of a buffer to handle a genuine spike in inquiries without missing the mark. We recommend it as a practical operating standard for agencies using automation, not as a claim that 90 seconds specifically has been proven superior to, say, 75 seconds or 2 minutes. The honest summary is simple: get as close to immediate as your systems allow, and treat anything past 5 minutes as a real, measurable loss.
Where the Hours Actually Go Before a Lead Gets a Reply
If the research is this clear, and has been available for close to two decades, the obvious question is why most agencies still respond so slowly. A widely cited 2014 study by WAV Group and Weichert, measuring response behavior across 384 US brokers, found an average response time to a buyer inquiry of 917 minutes, over 15 hours, with 48% of inquiries receiving no response at all.
That study is now over a decade old, and it would be reasonable to assume the gap has closed since then. It appears it largely has not. Industry surveys and platform data reported through 2025 and 2026 continue to describe real estate response times in the range of many hours on average, not minutes. The underlying causes are structural rather than a matter of individual agents being careless: leads arrive fragmented across a Zillow inbox, a website form, a direct text, and a phone call, with no single system surfacing all of them together, and a significant share of inquiries, commonly cited as roughly half, arrive outside standard 9 to 5 business hours, when no one is actively monitoring any of those channels.
Why This Is a Systems Problem, Not a Discipline Problem
It is tempting to treat slow response time as a training issue, something fixed by reminding agents to check their phones more often. The data does not support that framing. Even highly motivated, well trained agents cannot maintain a 90-second or even 5-minute response standard manually, across every channel, at every hour, indefinitely. The agencies that consistently hit fast response times are the ones that have built a system, typically some combination of unified lead routing and automated first response, that does not depend on a specific person being at their desk at the exact moment a lead arrives.
Why 78% of Buyers Never Give You a Second Chance
NAR's 2025 Home Buyers and Sellers Generational Trends Report puts a number on what is at stake. 78% of homebuyers report working with the first agent who responded to their inquiry. Separately, 95% of buyers rate responsiveness as very important when selecting an agent, and 75% report interviewing only one agent before committing to work with them.
Read together, these numbers describe a market with very little tolerance for a second chance. A buyer is not typically comparing five agents' responsiveness over a week and picking the best one. In most cases, the first agent who gives them a real, helpful response becomes the agent they work with, and everyone else who responds later is competing for a relationship that has already been decided.
The Practical Takeaway
If your agency's current response time is measured in hours, the research suggests this is not a minor optimization opportunity. It is very likely the single highest leverage change available to you, ahead of spending more on lead generation itself. Before increasing ad spend or switching lead sources, it is worth honestly measuring your own current response time, including nights and weekends, since that number is usually the real constraint on how many of your existing leads convert.
