Market Comparison Summaries (CMA Support)
Let Claude write the narrative around your comps — never the number
What Claude can and cannot do for a CMA
A Comparative Market Analysis has two parts: the data (comparable sales, adjustments, market trends) and the narrative that explains it to a client in plain language. Pulling and adjusting comps requires MLS access, licensed judgment, and knowledge of the specific property — that part is entirely yours. But turning a spreadsheet of comps into a clear, client-ready narrative is exactly the kind of synthesis Claude is built for.
Key principle: You determine the comps, the adjustments, and the final pricing recommendation. Claude helps you explain your analysis clearly. The moment a prompt asks Claude to decide a number, you’ve crossed from support tool into replacing licensed judgment — don’t do it.
Turning comp data into a narrative
I've pulled these comparable sales for a CMA. Turn this into a clear,
client-friendly narrative section (not a valuation opinion — just an
explanation of what the comps show). Keep it to 3-4 short paragraphs.
Subject property: 4bd/2.5ba, 2,400 sq ft, built 2005, Fairview Heights
Comp 1: 4bd/2ba, 2,300 sq ft, built 2003, sold $445,000, 0.3 mi away,
21 days on market
Comp 2: 4bd/2.5ba, 2,550 sq ft, built 2008, sold $472,000, 0.5 mi away,
14 days on market
Comp 3: 3bd/2.5ba, 2,150 sq ft, built 2001, sold $418,000, 0.8 mi away,
35 days on market
Explain what each comp suggests about the subject property's position
in the market, without stating a specific recommended list price —
I'll add that separately after my own analysis.Explaining market trends to clients
Clients often need context, not just comps — is the market moving up, slowing down, favoring buyers or sellers right now? You can hand Claude your own market read and get a clean explanation to send along with the CMA.
Write a short "market conditions" paragraph for a seller CMA packet,
based on this data I've gathered:
- Average days on market in Fairview Heights: down from 32 to 21
days over the last quarter
- Inventory: down 8% year over year
- Average sale-to-list price ratio: 99.2%
Explain what this means for a seller in plain language, 100-120 words,
no specific price predictions.Handling client questions about the CMA
Sellers often push back on pricing. Claude can help you prepare talking points grounded in the comps you’ve already gathered — but the actual answer in the room is still yours.
My seller thinks their home is worth more than my CMA suggests,
pointing to a renovated kitchen the comps don't have. Help me draft
3-4 talking points that acknowledge the upgrade while explaining how
comps and adjustments work, in a respectful, non-defensive tone.Compliance warning: Never present AI-generated narrative as an appraisal or a substitute for one. If a client’s question moves toward “what is this legally worth” in a context requiring a formal valuation (refinancing, estate, litigation), that’s an appraiser’s job, not a CMA and not an AI-assisted one.
Where this saves the most time
The packaging step — the part where you’d normally spend 45 minutes writing narrative paragraphs around a spreadsheet — compresses to minutes. That’s real time back in your week, as long as the analysis underneath stays yours.
Try it: Pull three real comps for a current listing (or a past one) and run them through the narrative prompt above. Compare the clarity against a CMA narrative you’ve written manually.
