The Zillow Research data dashboard publishes dozens of metrics every week, but most of them blur together without context. Learning to read three key indicators, however, gives you genuine insight into what's actually happening in any local market.
Zillow Research publishes public data on housing prices, inventory, and market velocity across thousands of zip codes and metro areas. Real estate agents, investors, and homebuyers use these numbers to benchmark their own deals and understand whether they're entering a buyer's market or a seller's market.
The catch: the metrics are only useful if you know what they're measuring. A 3% price cut share means something different than a 12% price cut share. Median days to pending tells you about buyer interest, not price strength. The Zillow Home Value Index (ZHVI) is an estimate, not a transaction price.
Understanding how to read each metric saves you from drawing false conclusions about what's actually moving in your local market.
The ZHVI is Zillow's estimate of the median home value in a given area. It's weighted by square footage and adjusted for seasonal variation. Zillow publishes ZHVI figures for single-family homes, condos, and all homes combined.
Here's what matters: the ZHVI is not an actual sale price. It's a statistical model based on recent transactions, property characteristics, and Zillow's algorithmic assessment of similar homes. When you see "median home value $425,000" on Zillow Research, that's the ZHVI, not the actual price homes sold for last week.
The ZHVI is most useful for tracking direction over time. If the ZHVI in your zip code rose 4% year-over-year, that tells you values are appreciating. If it's flat or declining, that tells you something different. Month-to-month ZHVI moves can be noisy, so look at three-month or year-over-year trends instead.
You should also use the ZHVI alongside transaction data. A rising ZHVI paired with declining median sale prices suggests that newer or better homes are selling relative to the overall stock, not necessarily that the market is strengthening.
Median days to pending measures how long a home sits on the market before an offer is accepted. It's one of the cleanest signals of market temperature.
When median days to pending drops, buyers are moving faster. This typically means demand is outpacing supply, prices are likely to rise, and sellers have leverage. When it rises, homes linger longer before getting an offer, which signals cooling demand or excess inventory.
The benchmark varies by region. In hot coastal markets, 20 days to pending is normal. In slower Rust Belt metros, 45 days might be typical. What matters is the trend: is the metric moving toward 0 or away from it?
One crucial detail: median days to pending doesn't include the time from pending to close. A home can sit pending for 30 more days while financing and inspection contingencies play out. Days to pending tells you about offer velocity, not how quickly deals actually close.
Watch for seasonal noise too. Median days to pending naturally rises in winter and falls in spring. Compare the same quarter year-over-year rather than month-to-month.
Price cut share is the percentage of homes that reduced their listing price during a given month. It's a direct measure of seller pressure.
Here's why this matters: when 3% of listings cut prices, the market is tight. Sellers can hold the line. When 15% of listings cut prices, sellers are struggling to move inventory at asking price. This is the market telling you that homes are overpriced relative to buyer demand.
Price cut share is one of the earliest warning signs of a shifting market. Before median prices decline, price cuts increase. Before days to pending stretch, price cuts spike. Investors and agents who watch this metric catch market turns earlier than those who only look at price trends.
The data:
- Below 5% price cut share: seller's market, inventory pressure
- 5% to 12% price cut share: balanced market, normal adjustment
- 12% to 20% price cut share: buyer's market, inventory relief
- Above 20% price cut share: stressed seller conditions, possible further price declines ahead
Note that seasonal variation is real here too. Price cuts tend to increase in late summer and fall. But year-over-year changes in price cut share are directional and reliable.
No single metric tells the whole story. You need to read them as a system.
If ZHVI is rising, median days to pending is falling, and price cut share is below 8%, you're in a classic seller's market. Homes are appreciating, selling fast, and sellers rarely need to cut price.
If ZHVI is flat, median days to pending is climbing, and price cut share is above 12%, you're in a buyer's market. Values aren't appreciating, homes sit longer, and sellers are cutting prices to move inventory.
If ZHVI is rising but price cut share is also rising, that's a warning signal. It means that while median values are higher, sellers are struggling to sell at higher prices. This usually indicates that a few high-end homes are skewing the ZHVI upward while the broader market is cooling.
The pattern matters more than any individual number.
Zillow Research publishes all of these metrics on its website at zillow.com/research. Data is typically updated weekly for zip codes and monthly for broader geographies. You can download raw data files for further analysis or view interactive maps.
The data is public, free, and historical. You can pull trends going back several years in most cases, which lets you compare current conditions to previous market cycles.
Learning to read Zillow Research metrics replaces intuition with fact. You stop wondering whether your local market is heating up or cooling down; you read the data and know.
Start by pulling the three metrics above for your target zip codes and comparing them to the same period last year. Look for divergence between them, not perfect alignment. Watch price cut share most closely, since it typically leads price and days-to-pending changes.
Over time, reading this data becomes automatic. You'll spot market turns before they hit the news, negotiate from better ground, and make decisions based on actual conditions rather than neighborhood gossip.
