Most homeowners spend more time picking a contractor than choosing the agent who will handle their biggest financial asset.
That’s not a guess. Research shows 81% of sellers contact only one agent before hiring (NAR Profile of Home Buyers and Sellers, 2024). And 78% of buyers go with the first agent who calls them back (NAR Profile of Home Buyers and Sellers, 2025).
Here’s why that’s a problem. The gap between a strong and weak agent on a $750,000 home in Northern Virginia can top $37,500 (Cunningham, Gerardi & Shen, Federal Reserve Bank of Atlanta, Working Paper 2022-11). Choosing based on who you know—or who responds first—is a costly way to make that call.
Why Online Reviews Won’t Help
The first thing most people do is check reviews. For real estate agents, reviews are almost useless as a quality signal.
A Consumer Federation of America study looked at 600 agents across 30 cities. It found that 80% of agents on Zillow are rated 5.0 stars—and 92% are rated 4.8 or higher (Consumer Federation of America, 2020). The reviews don’t measure results. They measure whether the client liked the agent as a person.
Being friendly and getting you a great deal are two different things. You can have a perfectly pleasant experience with an agent and still walk away with tens of thousands of dollars less than you should have. You’d never know the difference.
Sales Volume Doesn’t Mean What You Think
Most sellers assume the busiest agents are the best. The data says otherwise.
A study published in the Journal of Housing Research looked at 62,035 home sales. The researchers found that the most active agents—the ones closing the most deals—sold homes for 8% less than the least active agents (Beck, Scott & Yelowitz, Journal of Housing Research, 2022).
Why? Follow the math. On a $750,000 home, fighting for an extra $10,000 in sale price puts about $122 in a listing agent’s pocket after brokerage splits and taxes (Levitt & Syverson, Review of Economics and Statistics, 2008). If holding out for that money means two more weeks on the market, it’s not worth it to the agent. It is worth it to you.
The same researchers found that when agents sell their own homes, they stay on the market 9.5 days longer and sell for 3.7% more than similar client homes (Levitt & Syverson, Review of Economics and Statistics, 2008). They know how to get results. They just don’t always use that knowledge on your behalf.
The Performance Gap Is Real—and It’s Expensive
A Federal Reserve Bank of Atlanta study analyzed more than 2.3 million home sales. Moving from a 25th-percentile agent to a 75th-percentile agent increases your final sale price by 5–6% (Cunningham, Gerardi & Shen, Federal Reserve Bank of Atlanta, Working Paper 2022-11).
On a $750,000 Northern Virginia home, that gap is $37,500 to $45,000.
That’s more than many families save in a full year. And it’s a gap that most sellers don’t even know exists when they’re shaking hands with the first agent who called them back.
What Actually Predicts Whether an Agent Will Perform
The research points to a different set of questions than most sellers think to ask.
Local concentration matters. Agents who focus on a specific area near your home get better results. A 2024 study found that agents with concentrated local activity produced about $4,000 more in sale price than agents spread across a wide area (Fang & Hayunga, Real Estate Economics, 2024). An agent who “covers all of Northern Virginia” is not the same as one who knows your neighborhood street by street.
Original pricing accuracy matters. Look at what percentage of an agent’s listings close at or above the original asking price—before any reductions. An agent who overprices and then cuts is a different animal than one who prices accurately on day one.
Listing success rate matters. What percentage of their listings actually closed? In Northern Virginia, homes sell in about 27 days at median (NVAR full-year market data, 2025). If an agent routinely fails to close their listings, that tells you something important.
Why This Problem Keeps Happening
The real estate industry measures success by one number: how many homes you sell. Top producer rankings, brokerage awards, and agent marketing are all built on transaction count. Not your net proceeds. Not how your sale price compared to your neighbors.
This creates a gap. Selling a lot means you’re good at getting clients. It doesn’t mean you’re good at getting results for clients. Most sellers only transact once or twice in their lifetime. There’s no way to compare. You don’t have a benchmark.
The solution isn’t to distrust every agent. The solution is to use a better selection process—one built around the criteria that actually predict results.
Four Questions to Ask Before You Hire Anyone
- What is your sale-to-original-list-price ratio for the past 12 months—before any price reductions?
- How does your average days on market compare to the neighborhood average?
- What percentage of your listings actually closed in the past year?
- How many of your recent transactions were within five miles of my home?
These four questions will tell you more than any amount of time spent reading Zillow reviews.
The Vetted Agent Program exists because most sellers never ask these questions—and most agents never volunteer the answers. We run the evaluation for you, using the same structured process applied to vendor selection on major commercial real estate projects.
