A comparative market analysis, or CMA, is a professional, data driven estimate of a propertys likely sale price based on recent sales, active listings and market trends. We prepare CMAs for sellers, buyers and investors in Brooklyn and Williamsburg to show what similar properties actually sold for and why a particular price range is realistic.
What is a comparative market analysis
A CMA compares your property to recently sold homes and current listings that are genuinely comparable in size, condition, building type and location. It is not an appraisal. An appraisal is a lender ordered, floor by floor valuation that follows a specific standard. A CMA is the agent driven market view you use to price a listing, structure an offer or assess investment value.
What a CMA includes
- Recent comparable sales within the neighborhood and similar building types.
- Active listings and pending sales that show current market positioning.
- Adjustments for size, layout, condition, outdoor space and amenities.
- Market context such as inventory levels, days on market and buyer demand.
- Local factors that matter in Brooklyn, such as coop board rules, condo fees or neighborhood development plans.
Why a CMA matters in Brooklyn and Williamsburg
Pricing is the single most important decision when you sell. In a market like ours, where condo, coop and multifamily options sit within short walking distances, small price differences can change who sees your listing and how fast it sells. A CMA gives you a defensible price range based on local evidence, not guesswork.
For buyers a CMA shows whether an asking price is fair and where there may be negotiation room. For investors, a CMA combined with a rent roll analysis and cap rate review helps estimate cash flow potential for a multifamily purchase.
Key concepts to understand
- Comparables or comps. Recent sales of similar properties in the same submarket.
- Adjustments. Value changes made to comps for differences in size, condition or features.
- Active listings. Current inventory that sets buyer expectations, even if not yet sold.
- Days on market. How long similar listings stayed active before a sale.
- Price per square foot. Useful for condos and some coops, but less precise for unique townhouses or multifamily buildings.
Documents and data sellers should prepare
- Floor plans or accurate square footage measurements.
- Recent improvements and receipts for major work.
- HOA or coop maintenance fee statements and offering plan if available.
- Current lease information for tenant occupied units and a recent rent roll for multifamily properties.
How we build a CMA, step by step
- Define the market. We select comparables from the same block or nearest submarket in North Brooklyn, prioritizing sales in Williamsburg when available.
- Choose true comparables. We match building type, number of bedrooms, outdoor space and condition rather than relying on a single metric.
- Adjust for differences. We apply proven adjustments for size, renovations and features to place comparables on an even basis.
- Analyze active inventory. We include active and pending listings to understand buyer options right now.
- Present a price range and strategy. We explain the core number, a confident listing price range, and the factors that could push the final sale higher or lower.
Common questions about CMAs
Below we answer the questions we hear most from sellers, buyers and investors.
Pro tip: An accurate square footage measurement and clear photos of condition raise the reliability of any CMA. We often recommend a short home visit or professional measurement so comps match apples to apples.
Comparison: automated estimate versus agent prepared CMA
| Feature | Automated estimate | Agent CMA |
|---|---|---|
| Source of data | Public records and algorithms | MLS data, local sales, and agent knowledge |
| Adjustment for condition | Limited or none | Manual, condition based adjustments |
| Local market context | Generic | Specific to neighborhood and building type |
| Use case | Quick estimate or starting point | Pricing, negotiation and listing strategy |
When a CMA is not enough
Some transactions need more formal valuation. Lender appraisals are required for most mortgages. When a property is unusual, such as a unique townhouse or a complex multifamily building, an appraisal or specialist review may be warranted. For investors, pairing a CMA with a rent roll analysis and cap rate study gives a fuller financial picture.

We are a North Brooklyn broker centered in Williamsburg. Our CMAs commonly cover Williamsburg, adjacent North Brooklyn neighborhoods and nearby condo and coop markets. Local knowledge matters. Block level trends, coop board practices and building management can shift value in ways a citywide average misses.
Helpful resources and professional inputs
A robust CMA draws on several reliable sources and professional inputs rather than a single tool. Useful inputs include the MLS, public property records, recent closing statements and building offering plans. For tax questions we offer a complimentary tax consultation with our in house specialist Mario Saggese, CPA.
When you need a formal lender valuation, ask your mortgage officer about the appraisal process. For legal questions about coop boards or contracts, consult an attorney who handles real estate transactions.
Objections we hear and how we address them
Seller concern: My neighbor sold for more, so I should price higher. We review the full set of comparables and explain adjustments for finished basements, legal units or major renovations that justify different outcomes.
Buyer concern: Online estimates suggest a much lower price. We show the specific sales the automated tool used and explain why local judgment can shift a market estimate higher or lower.
