Understanding the Price Index

What it measures, what the categories mean, and how to use it

Home / Reports / Price Index / About

The Price Index answers one question: Are homes in this neighborhood selling for more or less than comparable homes elsewhere? It's not a quality rating. It's not a forecast. It's a pricing lens that helps buyers and sellers set realistic expectations.

How It Works

We analyze 12,102 recent home sales across 4 Triangle counties. For each sale, we use the home's size, age, location, and time of year to predict what it should have sold for based on broader market patterns.

Then we compare the actual sale price to that prediction. If homes in a neighborhood consistently sell above their predicted prices, that neighborhood has a higher Price Index. If they consistently sell below, it has a lower one.

Think of It Like This

Imagine two nearly identical 2,000-sqft homes built in 2010 — one in Neighborhood A, one in Neighborhood B. If the home in Neighborhood A sells for 15% more, the Price Index captures that difference. It measures the neighborhood premium (or discount) after accounting for what makes homes physically comparable.

The Price Index Spectrum

Every neighborhood receives a score from 0 to 100 and falls into one of three categories:

Value-Priced
Market-Aligned
Premium-Priced
0 20 50 80 100

Value-Priced (0–20)

Recent sales closed below what comparable homes sold for in other neighborhoods.

  • This does not mean the neighborhood is less desirable
  • Buyers may find more room to negotiate
  • Could reflect less buyer competition, newer community growth, or home conditions not captured in records

Market-Aligned (21–79)

Recent sales are consistent with what comparable homes sell for across the county.

  • The largest category — most neighborhoods fall here
  • A strong baseline for setting price expectations
  • Pricing reflects the broader market, not an outlier in either direction

Premium-Priced (80–100)

Recent sales closed above what comparable homes sold for in other neighborhoods.

  • This does not mean homes are overpriced
  • Buyers may face stronger competition and less flexibility
  • Often reflects high demand, established reputation, or location advantages

Real Examples from the Data

Here are three real Triangle neighborhoods — one from each category — to show what the numbers look like in practice.

Wendell Falls
Wake County
Premium-Priced
80.8 Price Index
+12.4% vs. Comparable
$519,750 Median Price
286 Recent Sales
Stone River
Wake County
Market-Aligned
43.6 Price Index
-2.1% vs. Comparable
$500,000 Median Price
152 Recent Sales
Edge Of Auburn
Wake County
Value-Priced
17.7 Price Index
-11.7% vs. Comparable
$450,000 Median Price
201 Recent Sales

What Do These Numbers Mean?

Take Wendell Falls as an example. With a Price Index of 80.8 and a premium of +12.4%, this tells us that homes here recently sold for about 12% more than what comparable homes sold for in other neighborhoods.

Meanwhile, Edge Of Auburn has a Price Index of 17.7 with a -11.7% adjustment. This means homes sold for about -12% less than comparable homes elsewhere — which could mean more negotiating room for buyers, not that anything is wrong with the neighborhood.

Using the Price Index

For Buyers

  • Premium-Priced areas often mean stronger competition. Come prepared with competitive terms and expect less room to negotiate.
  • Market-Aligned areas are a solid baseline — expect pricing that reflects the broader market.
  • Value-Priced areas may offer more flexibility on price and less competition. Pair this with the turnover report to find neighborhoods with more available inventory.

For Sellers

  • Premium-Priced areas may support a higher list price, especially with low turnover where supply is tight. Always confirm with recent comps.
  • Market-Aligned areas suggest pricing close to recent comparable sales is the most effective strategy.
  • Value-Priced areas call for strategic pricing. Work with your agent to position your home competitively given local dynamics.

What the Price Index Does NOT Measure

This is important. The Price Index is a pricing analysis, not a judgment on neighborhoods. Here's what it is not:

Not a quality or desirability rating. A lower Price Index does not mean a less desirable place to live. Great neighborhoods exist at every point on the spectrum.
Not a school, safety, or amenity rating. The model only looks at sale prices relative to home characteristics. It knows nothing about schools, crime, parks, or walkability.
Not a forecast. It reflects what happened in the last 12 months of closed sales, not what will happen next.
Not a replacement for professional advice. Use this alongside guidance from a licensed real estate agent who understands the full context of each community.

Why Pricing Differs Between Neighborhoods

Differences can come from many things the public records don't capture: interior renovations, upgraded finishes, lot views, HOA amenities, micro-location within a community, or simply the pace of demand. A Value-Priced label might reflect a newer community still establishing its market, homes that need updating, or simply a place where buyers face less competition. It's context, not a verdict.

Data Depth

Data Depth tells you how much sales data backs up a neighborhood's score. More sales mean a more reliable picture of where the neighborhood truly sits on the pricing spectrum.

Why It Matters

A neighborhood with 50 recent sales gives us a much clearer view than one with only 6. Both get scored, but you should weigh them differently. Data Depth makes that easy at a glance.

Deep 30+ sales. Plenty of data — the score is well-supported and unlikely to shift much with new sales.
Solid 15–29 sales. A good amount of data. The score is reliable, though a few unusual sales could nudge it.
Thin 5–14 sales. Limited data. The score gives a directional read, but treat it as a starting point rather than a definitive answer.

Neighborhoods with fewer than 5 qualifying sales are labeled "Insufficient Data" and excluded from rankings entirely.

How We Calculate It

Here's the process in plain language:

Collect sales data. We pull 29,580 recent single-family home sales from county public records across 4 Triangle counties.

Build a pricing model per county. We use a statistical model that predicts sale price based on home size, age, zip code, and time of year. Each county is modeled separately so neighborhoods are compared to local peers.

Measure the gap. For every sale, we calculate the difference between what the home actually sold for and what the model predicted. Then we average those gaps by neighborhood.

Stabilize small samples. Neighborhoods with fewer sales get "pulled toward the average" using a statistical technique called empirical Bayes shrinkage. This prevents a couple of unusual sales from creating misleading scores.

Score and rank. The stabilized neighborhood premiums are converted to a 0–100 scale and assigned a category. Each neighborhood also receives a Data Depth rating (Deep, Solid, or Thin) based on how many sales support the score.

Current Data

  • 29,580 single-family closed sales analyzed
  • 4 counties: Wake, Durham, Orange, and Chatham
  • 800 neighborhoods ranked
  • 365-day lookback window
  • Minimum 5 sales required per neighborhood

Common Questions

Does "Value-Priced" mean a neighborhood has a problem?
No. It means recent home sales closed at lower prices than comparable homes in other neighborhoods. This could reflect a newer community still building its track record, homes with older finishes, less buyer competition, or simply an area where prices haven't caught up with demand. Many Value-Priced neighborhoods are wonderful places to live — the label describes pricing dynamics, not quality of life.
Does "Premium-Priced" mean a neighborhood is overpriced?
No. It means buyers consistently paid more than what comparable homes sold for elsewhere. This often reflects genuine advantages — location, established reputation, amenities, or high demand. The market sets the price; we just measure where it lands.
Can a neighborhood's category change over time?
Yes. The index is updated weekly using the most recent 12 months of closed sales. As market conditions shift, neighborhoods can move between categories. A growing community with rising demand might move from Market-Aligned to Premium-Priced over time.
Why isn't my neighborhood listed?
We need at least 5 qualifying single-family home sales in the past 12 months to generate a reliable score. Smaller communities, those with very few recent sales, or neighborhoods known by different names in county records may not appear. Try the Neighborhood Finder to search by name.
Should I use this to decide where to buy?
The Price Index is one helpful data point, not the whole picture. Use it to understand pricing dynamics and set expectations, then work with a knowledgeable real estate agent who can factor in everything the data doesn't capture — schools, commute, community feel, future development plans, and your personal priorities.

This report is for informational purposes only and is not a substitute for professional real estate advice. Pricing dynamics reflect recent closed sales data from county public records and do not represent a judgment on neighborhood quality, safety, schools, or desirability. Always consult a licensed real estate professional before making buying or selling decisions.
