Whether it is a buyer’s or seller’s market is not a fixed label — it is a reading of four indicators at a specific place and time: months of supply, absorption rate, list-to-sale ratio, and median days on market. A market with low supply, a fast absorption rate, sale prices near list, and short days on market favors sellers; the reverse favors buyers. The Triangle rarely reads the same way in every submarket at once, so the metro-wide number can mislead.
What is months of supply, and how do you calculate it?
Months of supply (also called months of inventory) is the number of active listings divided by the average number of homes sold per month, and it estimates how long the current inventory would last at the current sales pace if no new listings were added. If a submarket has 60 active listings and homes are selling at 20 per month, that submarket has three months of supply. It is a snapshot, not a forecast — it changes as both the numerator and denominator move.
What is the absorption rate, and how does it relate to months of supply?
The absorption rate is the inverse relationship expressed as a percentage: the share of current inventory sold within a given period, usually a month. A higher absorption rate means inventory is being sold off faster, which corresponds to a lower months-of-supply figure. Some local boards report one, some report the other; they describe the same underlying pace of sales relative to supply from opposite directions.
What conventionally separates a buyer’s market from a seller’s market on months of supply?
The commonly cited convention runs in one direction: a lower figure favors sellers, and a higher figure favors buyers, with a middle range read as roughly balanced. The specific cutoffs are conventions repeated across the industry rather than a single codified standard, and different local boards and analysts draw the lines slightly differently — so treat the direction as reliable and any specific cutoff you see cited elsewhere as a rule of thumb, not a formula, worth checking against its source before you rely on it.
What is the list-to-sale ratio, and what does it tell you that months of supply does not?
The list-to-sale ratio compares the final sale price to the most recent list price, expressed as a percentage. A ratio at or above 100% means homes are selling at or above asking on average, which points toward a seller’s market; a ratio noticeably below 100% suggests buyers are negotiating price down, pointing toward a buyer’s market. Unlike months of supply, which measures inventory pace, the list-to-sale ratio measures actual negotiating leverage at the point of sale — it can move faster than supply figures when buyer or seller psychology shifts.
What does median days on market add to the picture?
Median days on market tracks how long, typically, a listing sits active before going under contract. A falling figure signals rising demand relative to supply before that shows up clearly in a months-of-supply calculation, because days on market reacts to buyer behavior in real time while months of supply is an averaged, lagging figure. Read together, a submarket with falling days on market, a rising list-to-sale ratio, and falling months of supply is moving toward sellers on all three measures at once — a stronger signal than any single indicator alone.
Why does the Triangle need to be read submarket by submarket rather than metro-wide?
Cary, Morrisville, Apex, and Raleigh do not move in lockstep, and neither do neighborhoods within any one of them. A new-construction corridor with active builder incentives can post a very different months-of-supply figure than an established, low-turnover neighborhood a few miles away in the same city, because the two pull from different buyer pools and different price bands. A metro-wide average blends new construction, resale, luxury, and starter-home segments that behave differently enough to cancel each other out in the topline number. A seller or buyer acting on the metro figure for a ZIP code-specific decision — pricing a listing, timing an offer — is working from a number that may not describe their actual competition.
Where do these figures come from, and how current are they?
Months of supply, absorption rate, list-to-sale ratio, and days on market are all derived from MLS data, typically published monthly by local Realtor associations or aggregated through MLS-fed platforms. They lag by the reporting cycle — a figure released this month describes last month’s closed activity, not this week’s showings. Anyone checking these numbers should confirm the reporting period stated alongside the figure, not just the number itself.
| Indicator | What it measures | Buyer’s market range | Seller’s market range |
|---|---|---|---|
| Months of supply | How long current inventory would last at the current sales pace | Higher figure — more inventory relative to sales pace | Lower figure — inventory sells off faster than it is replaced |
| Absorption rate | Share of active inventory sold within the period | Lower percentage | Higher percentage |
| List-to-sale ratio | Final sale price versus most recent list price | Below 100%, negotiated down from list | At or above 100%, at or above list |
| Median days on market | How long a typical listing sits active before going under contract | Longer — listings sit before an offer arrives | Shorter — listings go under contract quickly |
This table gives you the indicators and the direction each one points, not a number to plug in — that number changes every reporting cycle and is only accurate for the moment it was pulled. For current published figures at the metro and submarket level, see the market page, which tracks these indicators as they update rather than restating a single answer here that would age past its reporting period. Buyers timing an offer against these conditions may also want the due diligence period and closing costs in North Carolina; sellers deciding whether current conditions favor listing now should see should I sell my house now.
Who should not rely on these four indicators alone?
Anyone buying or selling a property type thin enough in a given submarket that a handful of transactions swing the numbers — new construction in a just-opened phase, or a luxury segment with few comparable closings — should not treat these metrics with the same confidence as a high-volume starter-home submarket, because small sample sizes make months of supply and list-to-sale ratio volatile from month to month. In that situation, a broker’s read of active showings and pending contracts in the immediate competition matters more than the published metro or even submarket figure.
