Why This Matters
Real estate decisions are often made on feel — "it seems like a hot market" or "I heard prices are dropping." But the data tells you exactly what's happening, and it gives you leverage that gut feel doesn't.
Buyers who understand these numbers know when to move fast and when they have room to negotiate. Sellers who understand them know whether their pricing is aggressive or leaving money on the table. Throughout this article, I'll use real numbers from Ellicott City's June 2026 market to show what each metric actually looks like in practice.
Days on Market (DOM)
What it is: How many days a listing has been active before going under contract.
What it tells you: DOM is one of the clearest signals of demand. A low median DOM means buyers are deciding quickly and competition is real. A high DOM means buyers have time to think, shop around, and negotiate.
In practice (Ellicott City, June 2026): The median DOM is 5 days. That means the typical home goes from listed to under contract before most buyers have scheduled a second showing. In this environment, buyers who wait for the weekend to "think about it" are almost always too late.
Watch out for relisted homes. When a home falls out of contract or expires and relists, the days counter often resets to zero. A home showing "2 days on market" may actually have been sitting for 60 days across two listing periods. Ask your agent to check the listing history.
How to use it as a buyer: If DOM is under 10 days in your target area, treat every showing as a potential same-day decision. Have your pre-approval updated, know your ceiling, and be ready to write.
How to use it as a seller: If your home sits past the median DOM for your neighborhood, something is off — usually price. The first two weeks on market are the most valuable. After that, buyers start asking why nobody else wanted it.
Months of Inventory (MOI)
What it is: How long it would take to sell all current listings at the current sales pace, if no new listings came on market.
What it tells you: MOI is the best single-number summary of whether buyers or sellers hold the power in a market.
- Under 3 months — seller's market. Low supply, high demand, prices firm or rising.
- 4–6 months — balanced market. Neither side has a strong negotiating advantage.
- Over 6 months — buyer's market. Homes sit longer, sellers negotiate, buyers have options.
In practice (Ellicott City, June 2026): MOI is 1.68 months — well into seller's market territory. There is less than 2 months of supply available at the current sales rate.
How to use it: MOI tells you the negotiating environment before you ever see a specific home. At 1.68 months, buyers should expect competition and come prepared. Sellers can price confidently and expect offers.
Sold-to-List Price Ratio
What it is: The sale price as a percentage of the original list price. Above 100% means the home sold for more than asking; below 100% means it sold for less.
What it tells you: This is the clearest measure of whether buyers are paying over or under asking — and by how much.
In practice (Ellicott City, June 2026): The median sold-to-list ratio is 104.5%. The average home sells for 4.5% above its list price. On a $750,000 listing, that's an additional $33,750.
How to use it as a buyer: If the ratio is above 100%, listing price is a floor, not a ceiling. An offer at asking price is unlikely to win in a competitive situation. Know the ratio in your target neighborhood before you write any offer.
How to use it as a seller: A ratio above 100% is a signal that pricing at market — or even slightly below — can generate competition and drive the final price up. Overpricing often produces the opposite effect: it sits, the ratio drops, and you end up accepting less than you would have at the right price from day one.
Price per Square Foot
What it is: Sale price divided by the home's finished square footage.
What it tells you: A useful tool for comparing similar homes. Less useful for comparing across neighborhoods, home types, or lot sizes.
In practice (Ellicott City, June 2026): The median price per square foot for sold homes is approximately $294–$301. That's a useful baseline — a 2,500 sq ft home priced at $800/sq ft is worth a second look; one priced at $250/sq ft may be underpriced or have significant issues.
Price per square foot has real limits. A 1,000 sq ft condo and a 4,000 sq ft single family home on half an acre are not comparable on a per-foot basis. Use this metric only within the same property type, same neighborhood, and similar condition. Don't let it override common sense.
Median vs. Average — and Why It Matters
Most real estate reports show median figures, not averages. There's a good reason for this.
The median is the middle value when all sales are sorted from lowest to highest. It's resistant to outliers — a handful of $2 million sales won't pull it dramatically upward.
The average adds all sale prices and divides by the number of sales. Three $500K homes and one $2M home produces an average of $875K — which tells you almost nothing about what a typical home costs.
When evaluating any market report, look for medians. They're the more honest number.
Putting It Together
None of these numbers exist in isolation. The power is in reading them together. Ellicott City in June 2026 shows:
- 5 days on market → buyers must move fast
- 1.68 months of inventory → demand far exceeds supply
- 104.5% sold-to-list → asking price is a starting point, not a ceiling
- $294–$301/sq ft → useful benchmark for pricing and evaluating specific homes
The picture those four numbers paint is consistent: this is a seller's market with real urgency. A buyer who understands that going in makes better decisions than one who's discovering it after losing their second home.
