Comparative Market Analysis (CMA)

Quick Definition

A comparative market analysis (CMA) is an estimate of a property's fair market value based on the recent sale prices of similar properties, called "comps" or comparables, in the same geographic area. Real estate agents prepare CMAs, typically at no charge, to help sellers set a listing price and help buyers make competitive offers. Unlike a formal appraisal conducted by a licensed appraiser, a CMA is not a certified valuation and carries no legal weight in lending decisions.

What It Means

Setting the right price is one of the most consequential decisions in a real estate transaction. Price too high and the home sits on the market, accumulating stigma and eventually requiring price cuts. Price too low and the seller leaves money on the table, sometimes tens of thousands of dollars.

A CMA gives agents and their clients a data-driven starting point by anchoring the subject property's value to what buyers have actually paid for comparable homes nearby. The logic is straightforward: a well-informed buyer in a free market will not pay more for Property A than they would for an identical Property B next door.

In 2026, this matters more than usual. The U.S. housing market has shifted toward buyers more than at any point since before the pandemic. According to Realtor.com's Q2 2026 Market Clock report, 70% of the top 100 metros now favor buyers or are trending in that direction, up from 52% a year ago. Asking prices have fallen year-over-year for eight straight months, with a 2.5% national decline in June 2026, the steepest annual drop in the data series since 2017. Sellers are pricing more realistically, and a well-prepared CMA is the tool that grounds those pricing decisions in data rather than hope.

CMAs are also called Broker Price Opinions (BPOs) in some contexts, particularly when used by banks to value properties in foreclosure or short-sale situations.

What Goes Into a CMA

A thorough CMA analyzes four categories of properties:

The Comparable Selection Criteria

Agents select comps based on factors that most influence buyer decisions:

• Location: Same neighborhood, school district, ideally same street or block
• Size: Similar square footage (typically within 10-15%)
• Bedroom/bathroom count: Matching configuration
• Lot size: For single-family homes, lot size matters significantly
• Age and condition: Similar age, construction quality, and condition
• Recency: Sales within last 3-6 months (or 12 months in slow markets)
• Style: Ranch vs. two-story vs. split-level can affect value

How a CMA Is Prepared: Step by Step

1. Pull the MLS data: Agent searches the MLS for recently sold properties matching the subject property's criteria within a defined radius (typically 0.5 to 1 mile in urban areas; wider in rural)
2. Select 3-6 best comps: Choose the most similar properties. Closer, more recent, and more similar is better.
3. Adjust for differences: Add or subtract value for differences between comps and the subject property
4. Analyze active competition: What similar homes are currently listed for tells you what buyers are comparing your home to
5. Review market trends: Is the market appreciating or declining? Adjust older comps accordingly. In 2026, many markets are experiencing price softening, so older comps may need downward adjustments.
6. Arrive at a price range: Calculate price per square foot and adjusted sold prices to establish a defensible range

Adjustments: The Science and Art of CMAs

No two homes are identical. Agents adjust comp prices to account for differences:

Adjustment values vary significantly by market, price point, and local buyer preferences. A pool adds more value in Phoenix than in Minneapolis. In a softening market like 2026, time adjustments may be negative rather than positive, reflecting declining prices.

Sample CMA Output

Subject Property: 4BR/2BA, 2,000 sq ft, built 1995, updated kitchen, 2-car garage, 0.25 acre lot

CMA Conclusion: Suggested list price range of $475,000 to $495,000, with $485,000 as the most defensible midpoint.

CMA vs. Appraisal: Key Differences

A lender will order an independent appraisal before approving a mortgage. The CMA cannot substitute for this. The appraisal is a legal requirement for lending; the CMA is a pricing tool for buyers and sellers.

Price Per Square Foot: A Quick Cross-Check

Calculating price per square foot is a useful sanity check on CMA conclusions:

Comparable sales in subject neighborhood:

• Comp 1: $485,000 / 2,050 sq ft = $236/sq ft
• Comp 2: $460,000 / 1,900 sq ft = $242/sq ft
• Comp 3: $505,000 / 2,100 sq ft = $240/sq ft
• Average: $239/sq ft

Subject property check: $239/sq ft x 2,000 sq ft = $478,000, consistent with the CMA range above.

In 2026, price per square foot trends are declining in many markets. Realtor.com reported a 2.1% year-over-year drop in list price per square foot nationally as of June 2026, with declines in 33 of the top 50 metros. Agents should factor in these downward trends when using older comps.

The 2026 Market Context

The housing market in 2026 looks very different from the 2021 to 2022 seller's market. Mortgage rates have hovered around 6.5% for much of the year, according to Realtor.com's midyear forecast. Existing-home sales are projected to total 4.10 million, with pending sales rising for seven consecutive months through June. Inventory is growing, up 3.6% year-over-year, giving buyers more options and negotiating power.

For CMAs, this means:

• Sellers need to price competitively from day one. Overpriced homes sit longer and require steeper cuts.
• Buyers can use CMAs to support lower offers with data, especially in markets where prices are declining.
• Agents should weight recent comps more heavily, as older sales may reflect higher market conditions that no longer exist.
• Expired and withdrawn listings are particularly informative right now, showing what happens when sellers resist market realities.

Key Points to Remember

• A CMA is a professional opinion of value, not a certified appraisal. It cannot be used for mortgage purposes.
• The best comps are recent, nearby, and similar. Prioritize recency and proximity above all.
• Adjustments are added or subtracted to comp prices to account for feature differences.
• Active listings show competition; expired listings reveal overpricing traps.
• CMAs are typically free from listing agents. Consider requesting one before listing or making an offer.
• Price per square foot is a useful cross-check but ignores location and quality differences.
• In 2026's buyer-friendly market, pricing realism matters more than ever. Use CMAs to ground decisions in data.

Common Mistakes to Avoid

• Using outdated comps: In a rapidly changing market, 6-month-old sales may be significantly mispriced today. In 2026's declining-price environment, older comps may overstate value.
• Ignoring location differences: A house one block outside a top school district can sell for 10-15% less.
• Over-relying on price per square foot: A luxury kitchen adds more than its prorated share; a dated bathroom subtracts disproportionately.
• Confusing list price with sold price: Active listings are asking prices. Only closed sales reflect what buyers actually paid.
• Emotional pricing: Sellers often believe their home is worth more than the market supports. A good CMA provides objective grounding.
• Ignoring pending sales: Pending sales are the most current indicator of where the market is heading. They show what buyers are actually agreeing to pay right now.

Frequently Asked Questions

Q: Can I do my own CMA without an agent? A: You can research recent sold prices on sites like Zillow, Redfin, and Realtor.com, but public data often has gaps (sale price not always disclosed in some states) and lacks the MLS detail that agents access. You can approximate a CMA, but professional agents have access to more complete data and can make informed adjustments based on local knowledge.

Q: How many comps do I need for a reliable CMA? A: At least three to five recently sold comps are needed for statistical reliability. In rural areas or unique properties, finding good comps can be challenging. Agents may need to widen the search radius or go back further in time, noting that market conditions may have changed.

Q: What if there are no good comps? A: Unique properties (distinctive architecture, unusual lot, very large or small square footage) present a true comparability challenge. In these cases, agents may use price-per-square-foot analysis, cost approach (cost to rebuild), income approach (for investment properties), or refer to an appraisal. High-end luxury homes often have sparse comparable sales by definition.

Q: How does a CMA help me as a buyer? A: A buyer's CMA helps you determine whether a listing price is fair, supports a competitive offer price, and identifies when a home is overpriced relative to comparable sales. In 2026's buyer-friendly market, a CMA can give you the data to negotiate a lower price with confidence.
