If you’ve talked to a real estate agent in the last year, you’ve probably heard the phrase “pre-marketing” more than once. It’s everywhere right now. Zillow changed its rules around it. Compass built an entire strategy around it. Industry trade publications can barely get through a week without writing about it.
But most of the coverage is aimed at agents and industry insiders, not homeowners in Reston trying to figure out what it actually means for them. So let’s bring it down to earth.
Two separate studies — one from an academic economist with 20 years of data, one from Compass’s own research team analyzing thousands of transactions — have reached the same basic conclusion. Sellers who start their listing off-market before going live on the MLS tend to get better outcomes. Not always. Not automatically. But the data points clearly in one direction, and it’s worth understanding why.
Here’s what the research says, what we’ve seen firsthand working with sellers in Reston and Herndon, and how the three-phased marketing approach actually works in practice.
What the Research Actually Says
The University of Georgia Study
Earlier this month, a professor in the real estate program at the University of Georgia named Darren Hayunga submitted a paper to the Journal of Urban Economics. He had spent years analyzing MLS data from 2002 to 2022, specifically looking at what happens to homes that sell off-MLS compared to homes that sell through the traditional MLS process.
His finding: private listings sold for a 1.7% premium on average. At luxury price points, that premium jumped to 8%.
The reason he found was something he calls the “negotiation tax.” It’s a simple but important idea. When a home goes live on the MLS, buyers arrive knowing they’re in a traditional negotiation. They expect to offer less than list price. That expectation is baked into every offer. Sellers on the MLS are essentially fighting against that current every time.
Homes sold off-MLS sidestep that dynamic. Buyers in a private setting have less leverage to anchor low, and they know it. The result, across 20 years of data, was a meaningful and consistent price advantage.
Hayunga also found that sellers avoided two other MLS-specific problems: days-on-market accumulation and visible price drop history. Both of those signal weakness to buyers and invite lower offers. Keeping a listing out of the MLS data stream, at least initially, protects the seller from those visibility problems.
One more thing worth noting: Hayunga specifically tested whether this premium was the result of dual agency — agents trying to double-end deals by keeping listings in-house. It wasn’t. The price premium showed up equally in arm’s-length transactions where both sides had independent representation. That matters because it tells us the outcome is driven by the structure of the sale, not by agent self-interest.
The Compass Study
Compass released its own research in February 2025, covering every sell-side transaction the company handled in 2024. Using a hedonic regression model that controlled for property type, location, and seasonality, the company found that pre-marketed listings were associated with a 2.9% higher close price compared to listings that went straight to the MLS.
The additional findings were just as compelling. Pre-marketed homes received accepted offers 20% faster once they went active on the MLS — about 8 days sooner, on average. And only 13% of pre-marketed listings experienced a price drop after going live, compared to 19% of listings that skipped pre-marketing. That’s roughly 30% fewer price drops.
Compass’s explanation aligns with the UGA findings. Pre-marketing gives sellers a window to test pricing, gather real feedback, and fine-tune their approach before the listing goes public and the clock starts ticking. Once the home hits the MLS, it arrives with momentum rather than uncertainty.
Put the two studies side by side and you get something worth paying attention to. An independent academic economist says the data supports pre-marketing. The company that has built the most visible pre-marketing program in the country says its own numbers confirm it. They’re not working from the same data set. They’re not coordinating their conclusions. They just found the same thing.
What This Looks Like for Reston and Herndon Sellers
Northern Virginia is not a slow, forgiving market. Reston and Herndon attract buyers who are often relocating for government or tech work, moving fast, and doing a lot of online research before they ever walk into a home. They know the market. They watch days on market. They notice price drops. A listing that sits for three weeks and drops $25,000 is going to get a much different reception than a listing that arrives fresh.
That’s exactly why the pre-marketing window matters here. The ability to come onto the MLS with no accumulated days on market, no price drop history, and no stale photos — that’s a competitive edge that shows up in the offers you receive.
We’ve worked with sellers in Reston who went through this process and sold before they ever finished getting the house ready. The pre-marketing phase created enough buyer interest that the right offer came in before the renovation checklist was complete. That’s not a fluke. It’s the product of controlling the timing and protecting the listing’s reputation before it goes public.
How the Three-Phased Marketing Strategy Works
The approach Compass developed — and the one we use with our clients — runs in three stages. Each one serves a different purpose.
Phase 1: Compass Private Exclusive
The home is listed within the Compass agent network. It’s not on Zillow, Redfin, or Realtor.com. It’s not on the MLS. But it’s visible to every Compass agent and their buyers. This phase gives sellers something valuable: real-world feedback from actual buyers without any of the public exposure.
If the pricing needs adjustment, you can do it here with no one the wiser. If buyers ask the same question about the basement or the HVAC, you know what to address before going public. The clock isn’t running. No days on market are accumulating. You’re gathering intelligence.
This is also the phase where we sometimes see sellers get offers. Motivated buyers who are working with Compass agents know about Private Exclusives and they move on them. If the right offer comes in during Phase 1, the seller can accept it and never go to the MLS at all.
Phase 2: Compass Coming Soon
The listing goes public on Compass.com, visible to all consumers, but still not on the MLS and not on third-party portals. This is the broader soft launch. Buyers who are actively searching and who find the home on Compass.com can register their interest. Agents from other brokerages can show their clients the listing.
This phase builds anticipation. When a listing shows up on the MLS and already has documented buyer interest, that changes the dynamic. It signals demand. Buyers who have been waiting to act know they need to move.
Phase 3: Active on the MLS
The home goes fully live. Zillow, Redfin, Realtor.com, all the third-party portals. Full MLS exposure. Maximum buyer pool.
The key is that by this point, the home has already been tested, refined, and positioned for success. The pricing has been validated. The presentation has been tightened. The feedback from Phases 1 and 2 has been incorporated. The listing arrives on the MLS in the best possible condition.
The Part About Getting the House Ready (and Sometimes Not Needing To)
This is where our process as a team differs from just running through a checklist.
When we take on a seller client, we start having conversations about the home well before it lists anywhere. What needs to be done? What’s cosmetic versus structural? What will actually move the needle for buyers in this neighborhood? A house in Reston’s South Lakes area will get evaluated differently than one in Herndon near Dulles. Buyer profiles differ. Price expectations differ. What they respond to differs.
During the pre-marketing window, we’re doing that work alongside the listing. We’re coordinating with contractors if needed, staging the home, getting photography done, preparing the marketing materials. The pre-marketing phase isn’t just a waiting room — it’s a preparation runway.
And sometimes the home sells before the runway is fully used.
We’ve had sellers go through the Private Exclusive phase with a home that still had a punch list of items to address. A buyer came in who loved the location, loved the bones of the house, and made a strong offer. The seller accepted. The buyer’s inspector found the same things the seller already knew about. They negotiated appropriately, and the deal closed. The seller never had to manage a full renovation, never had to deal with contractor delays, never had to vacate the house for weeks. They got a fair price, and they kept their sanity.
That’s not a trick. It’s just smart sequencing. Pre-marketing creates the conditions for that kind of outcome.
A Few Things Worth Knowing Before You Decide
Pre-marketing works well in most situations, but it’s not a universal answer. Here’s an honest take on when it helps most and when you should think carefully.
It works especially well when your home is in a price range where buyers have options, because a fresh listing with no history commands more attention. It works well when the home needs some preparation, because you have time to do it without the pressure of a live listing. It works well in Reston and Herndon specifically because the buyer pool here is informed and they pay close attention to listing history.
It works less cleanly when you’re in a fierce seller’s market where everything is getting multiple offers the day it lists regardless. And it’s not a substitute for good pricing. A home that’s overpriced in Phase 1 will get honest feedback — which is actually useful — but it won’t sell at an inflated number just because it’s private.
What the research confirms is that the pre-marketing window, used properly, gives sellers information and control they don’t have when they go straight to the MLS. That’s worth something. The 1.7% to 2.9% average premium in the studies represents real money. On a $750,000 home in Reston, 2.9% is about $21,750.
What Happens When You Work with Greater Reston Living
Kathy and I work through this process with every seller who’s interested in it. We start with a walk-through and an honest conversation about the home’s current condition, what buyers in this market are expecting, and what the realistic price range looks like. From there, we build a plan.
The pre-marketing phases are built into how Compass works, which means we have access to a significant network of buyers and agents right from the start. We know the Reston and Herndon markets closely — the neighborhoods, the schools, the commuter patterns, the buyer profiles at different price points. That local knowledge informs how we price, how we present the home, and how we sequence the marketing.
If you’re thinking about selling your home and want to understand whether this approach makes sense for your situation, we’re glad to have that conversation. There’s no pressure and no commitment. Just a real discussion about what the process looks like and what you might reasonably expect.
The research is clear that pre-marketing, done well, tends to produce better outcomes for sellers. The data comes from 20 years of transactions and from one of the largest real estate companies in the country. It points in the same direction. For homeowners in Reston and Herndon who are thinking about selling, that’s worth knowing.
