The 30-second version

  • A CMA is a market read, not a guess. It sets fair value by comparing your home to similar ones that recently sold nearby in the Triangle.
  • The adjustments do the real work. A two-car garage, a renovated kitchen, an extra bath—each one adds or subtracts value against the comps.
  • Active, sold, and pending tell different stories. Sold shows what buyers paid, active shows your competition, pending hints where prices are heading.
  • A CMA is not an appraisal or a Zestimate. I build it from local data and 17+ years of walking these neighborhoods—not an algorithm guessing from afar.

Price a home right in the City of Oaks and it can pull multiple offers in a weekend. Price it wrong and it sits—then you're chasing the market down. The tool that keeps you on the right side of that line is a Comparative Market Analysis, or CMA.

In my 17+ years across Raleigh, Durham, and Chapel Hill, I've watched a sharp CMA make or break a deal. Here's what one actually tells you, how I build it, and where its limits are.

What a CMA Is

A CMA determines the fair market value of a property by comparing it to similar homes that recently sold in the same area. Think of it as a financial X-ray of the local housing market—it reveals the structures holding property values up in places like Cary, Chapel Hill, and Durham.

To build that picture, I compare your home—the subject property—against recent sales on a handful of concrete factors:

  • Square footage
  • Number of bedrooms and bathrooms
  • Lot size
  • Age of the home
  • Location within the neighborhood
  • Recent upgrades or renovations

Read those elements together and you get a clear number—what your home is worth today, or what you should expect to pay for one you want to buy.

A CMA is a market read, not a hope. It tells you where buyers have actually been putting their money.

Why a CMA Matters So Much Here

The Triangle—Raleigh, Durham, and Chapel Hill—runs on a strong job market, top universities, and a quality of life that keeps people moving in. That makes our market both exciting and demanding. Four reasons a solid CMA is your best friend in it:

The market shifts fast

A tech-company expansion or university growth can move prices quickly. A current CMA keeps you ahead of the change instead of behind it.

The neighborhoods are anything but uniform

From the historic streets of Oakwood to the modern feel of North Hills, each area has its own character. A CMA accounts for those differences instead of flattening them into one number.

Pricing is your competitive edge

In active markets like Apex or Morrisville, accurate pricing is the difference between winning and losing a deal.

It reads investment potential

For buyers eyeing areas like Research Triangle Park, a CMA highlights growth trends and the returns behind them.

How I Build a CMA in the Triangle

Identify the comps

Every CMA starts with the right comparable properties—the comps. Here that means looking past the address to three things: proximity (ideally within a mile, though in rural pockets of Wake or Orange County I widen that), recency (sales from the last 3–6 months to catch current conditions), and property features (matching size, style, and condition as closely as I can).

In Downtown Durham or Cameron Village, where property types shift block to block, I pay extra attention to matching architectural styles and uses.

Gather the detail behind each sale

Once the comps are set, I dig into the numbers behind them—not just the headline price:

  • Sale prices, including any concessions or special terms.
  • Days on market, which tells you how hot or cool an area runs.
  • Price per square foot, useful in new-construction areas like Holly Springs.
  • Special features—a finished basement, a pool, or smart-home technology can move value hard.

Make the adjustments

This is where the craft comes in. I adjust each comp based on how it differs from your home. If a comp has a two-car garage and yours has a one-car, I subtract value from the comp. If your kitchen is newly renovated and the comps aren't, I add value to yours. In the Triangle, proximity to the American Tobacco Campus in Durham or Centennial Campus in Raleigh weighs on those adjustments too.

Read the market trends

Your home doesn't sell in a vacuum, so I read the wider signals: employment news from major employers like IBM, Cisco, or Red Hat that shapes future demand; school-district performance, which moves values fast in areas like Cary or Wake Forest; and infrastructure work like the Complete 540 project that can reshape an area's appeal.

Compile and present it

The last step is putting it into a clear, usable report: a summary of comparable properties, adjusted values with the reasoning, the market-trend read, and a recommended price range for selling or offering.

What a CMA Does and Doesn't Do

A CMA is powerful, but it isn't everything. Knowing its edges keeps your expectations honest.

What a CMA includes

  • Recent nearby sales matched to your home
  • Adjustments for garages, renovations, and features
  • Days on market and price per square foot
  • Local trends—jobs, schools, infrastructure
  • A recommended price range to list or offer

What it can't do

  • Serve as the lender's official appraisal
  • Replace an on-site inspection of condition
  • Guarantee an exact final sale price
  • Predict appreciation with certainty
  • Match a local read from an online estimate alone

CMA, Appraisal, and Online Estimate

People mix these up constantly. They answer different questions and carry different weight.

ToolWho produces itWhat it's for
CMAYour agent, from local sold, active, and pending dataSetting a competitive list price or a smart offer
AppraisalA licensed appraiser, on the lender's behalfConfirming value for the mortgage
Online estimateAn algorithm, from public recordsA rough starting point, nothing more

An online tool gives you a number from a distance. A CMA gives you a number from someone who has walked the block.

How the CMA Works For You

If you're selling

Price competitively, and in active markets like North Hills or Brier Creek that can pull multiple offers. Where the CMA shows features that add real value—solar panels, smart-home systems—lead with them in your marketing. And watch the seasonal read: family homes in Cary often move better in spring as buyers line up before the school year.

If you're buying

You negotiate from data instead of guesswork. A CMA helps you spot undervalued homes in up-and-coming areas like East Durham or parts of Southeast Raleigh, and the trends inside it inform how a property might appreciate.

How to Read the CMA I Hand You

  1. Start with the sold comps. These are real transactions—what buyers actually paid for homes like yours.
  2. Check the active listings. That's your competition right now if you're selling, and your alternatives if you're buying.
  3. Note the pending sales. They point to where prices are heading between the sold and active numbers.
  4. Follow the adjustments. See why each comp moved up or down against your home—garage, kitchen, lot, condition.
  5. Land on the range, not a single number. The recommended price range is where strategy begins, shaped by your timeline and goals.

A number on a screen is a starting point. A CMA built on Triangle sold, active, and pending data—read by someone who knows these neighborhoods—is a strategy. If you're weighing a list price or an offer, my team and I will build you one and walk you through every adjustment. Reach out and let's put real numbers behind your next move.
