There is a number written on a whiteboard in the RESMP office, and we walk past it every single day: 3,800,000,000. Three-point-eight billion dollars. People assume it's a fantasy — the kind of round, ambitious figure every startup scribbles down to feel important. It isn't. It's the output of a very specific piece of arithmetic, built entirely on numbers the real estate industry already agrees on. The strange part isn't the size of it. The strange part is that the road to it runs straight through a single statistic that almost everyone misreads — and once you see it, you can't unsee it. We're going to walk you to that number step by step. But here's the deal: we will not tell you the trick until the very last section. Stay with us.

A number, and a promise
Most articles give the ending away in the headline. This one won't. Here's all you need up front: $3.8 billion is not our revenue today — we're an early-stage startup, and we'll be the first to say it's a target, not a trophy. It's the size of a prize sitting out in the open, inside a market nearly everyone assumes is completely locked up. By the end of this page you'll have done the math yourself and landed on the same figure. You'll also understand why almost nobody else is chasing it the way we are. Deal? Good. Let's build it from scratch.
First, forget RESMP for a second
Picture the U.S. housing market from 30,000 feet. Roughly five million existing homes are bought and sold every year. It is enormous, old, and — on the surface — utterly settled. About nine out of ten of those sellers hire a real estate agent. They have for decades. The names on the yard signs change; the basic deal does not. If you were a betting person staring at that picture, you'd call it a closed game. No room. Every house already has a process, a professional, and a commission bolted to it. That is exactly what most people see. It is also exactly why they miss the number on our wall.
Everyone's been watching the wrong rebels
For twenty years, the "disruption" of real estate had a designated hero: the do-it-yourselfer. The seller who skips the agent, plants their own sign, and keeps the commission — the For-Sale-By-Owner, or FSBO. Every pundit hunting for the future of real estate kept one eye locked on this group, waiting for them to take over the market. So how's the revolution going? Look at the chart. In 1985, about 21% of sellers went it alone. Today it's around 5% — the lowest figure the National Association of Realtors has ever recorded, and still drifting down. The DIY uprising didn't conquer real estate. It quietly collapsed. Which raises a very awkward question for a company with a ten-figure number on its wall…
…so if the rebels lost, where's the $3.8 billion?
Here's the trap nearly everyone falls into. They see that shrinking 5%, conclude there's no real appetite to change how homes are sold, and walk away: "People tried cutting out the agent, they didn't like it — case closed." But that conclusion quietly assumes something false: that the only two options are (a) pay a full traditional commission, or (b) do everything yourself. It assumes the 5% who left and the 95% who stayed feel completely differently about the deal. They don't. And the gap between what those 95% say and what they actually want is precisely where the entire number lives.
What sellers say vs. what they quietly resent
Ask sellers why they keep hiring an agent and the answers are consistent and rational: marketing reach, access to the MLS, pricing expertise, negotiation, and someone to handle the contracts and disclosures so they don't get sued two years later. Notice what is not on that list: "because I love paying five to six percent." Sellers don't stay for the price — they stay for the expertise, and then they grit their teeth at the bill. Survey after survey lands on the same finding: the dominant motivation isn't to fire the agent, it's to stop overpaying the agent. The 5% who went FSBO weren't the whole rebellion. They were just the few willing to throw out the professional to escape the price. The other 95% want something almost nobody was really offering them: keep the pro, lose the markup.
We don't sell to the 5%. We sell to the space between.
This is the trick — and now we'll say it plainly. RESMP is not a FSBO platform, and it is not a traditional brokerage. We are built for the enormous, ignored middle: the sellers who absolutely want a real, skilled agent, and absolutely do not want to pay a 1985 commission to get one. On RESMP, those sellers compare verified local agents and the terms they offer — from lean low-commission pros to full-premium service — and pick the fit. They keep the human. They cut the markup. That's the whole idea. And here's why that FSBO chart was a red herring: the prize was never the 5% who leave. It's a slice of the 95% who stay but are quietly furious about the bill. Look at the second chart — even a modest share of that middle is multiples larger than the entire FSBO market the headlines can't stop talking about.
Now the math — the part we promised
So, the whiteboard. Start with the ~5 million homes sold in the U.S. every year. We are not chasing the 5% FSBO fringe; we're chasing the commission-conscious middle. Assume that over the next several years RESMP earns the trust of just one in eight of those sellers — 12.5%, or about 625,000 homes a year. At a U.S. median sale price near $400,000, a lean listing-side commission of about 1.5% works out to roughly $6,000 per home. Multiply it through: 625,000 homes × $6,000 ≈ $3.75 billion in commission flowing across the platform every year. Round it for the wall: $3.8 billion. In the name of honesty: those are forward-looking assumptions, not a promise — the median moves, the capture rate is something we have to earn one happy client at a time, and "commission volume" is not the same thing as profit. But every input is a real, widely-agreed number, and the conclusion is hard to dodge: the money was never in the 5% who left. It was in the space between FSBO and full price — and that space is measured in billions.
Why we just handed you the secret
You might wonder why a company would publish the exact thinking behind its biggest bet. Simple: the insight isn't the moat — the execution is. Anyone can read that the middle is the prize. Very few can actually build the thing that earns sellers' trust, verifies agents, matches on fit instead of ad spend, and lets great professionals win by being great rather than by being cheapest. That's the part we're heads-down building. If you're a seller who's tired of choosing between "do it all yourself" and "pay full freight," that middle is finally a place you can stand. And if you're an agent who is genuinely good at the job, a 625,000-door opportunity isn't a threat — it's your next decade of clients. The number on the wall was never a fantasy. It's a map. Now you've seen it too.
Frequently Asked Questions
Is RESMP a For-Sale-By-Owner (FSBO) service?
No — in spirit it's the opposite of FSBO. RESMP keeps a skilled, verified agent in the deal; what it changes is the price. Sellers compare agents and the commission terms they offer, so they keep the expertise without overpaying. FSBO removes the professional; RESMP removes the markup.
Where does the $3.8 billion figure actually come from?
It's a forward-looking model, not current revenue. Take ~5 million U.S. home sales a year, assume RESMP eventually serves about one in eight commission-conscious sellers (~625,000 homes), at a ~$400,000 median and a lean ~1.5% listing-side commission (~$6,000 per home): 625,000 × $6,000 ≈ $3.75 billion in annual commission volume across the platform. The inputs are public industry figures; the capture rate is the part RESMP has to earn.
Does using RESMP mean settling for a worse agent?
No — and that's the whole point. RESMP lists agents across the full spectrum and matches on local expertise, track record, and communication fit, not just price. Plenty of excellent agents offer competitive terms to win motivated, ready-to-move clients. You're choosing a fit, not settling for cheap.
Is the FSBO market really shrinking?
Yes. For-sale-by-owner has fallen from roughly 21% of sellers in 1985 to about 5% today — the lowest the National Association of Realtors has recorded. The lesson isn't that sellers love commissions; it's that they value professional help and would rather pay less for it than go without it entirely.
