7 Real Estate Use Cases You Can Test This Week

I went through Anthropic’s release and translated every capability into something you can actually use.

Credit where it’s due — these are based on Anthropic’s published use cases. I just made them relevant to your business.

1. Underwriting Models That Actually Work

What Anthropic said: “Claude Opus 4.5 sets a new standard for Excel automation and financial modeling.”

What this means for you:

You can now ask Claude to build or modify your underwriting models with real logic.

Not summaries.

Actual cell formulas.

Input checks.

Sensitivity tables.

Try this prompt:

You are a senior real estate acquisitions analyst.

Build me a multifamily underwriting model in Excel with:
- Purchase price, units, and average rent inputs
- Operating expense assumptions (taxes, insurance, management at 5%, repairs at 5%, vacancy at 5%)
- Debt service calculations (loan amount at 75% LTV, 7% rate, 30-year amortization)
- NOI, cash flow, cap rate, and cash-on-cash return outputs
- A sensitivity table showing cash-on-cash returns at 3 different purchase prices and 3 different interest rates

Use proper Excel cell references. Label all assumptions clearly. Make it easy for me to modify inputs.

2. Chrome-Based Deal Research (Without Tab Chaos)

What Anthropic said: “Claude for Chrome lets Claude handle tasks across your browser tabs.”

What this means for you:

Claude can now read, extract, and organize information from multiple browser tabs.

LoopNet.

CoStar.

County assessor sites.

Redfin.

All at once.

Try this prompt:

I have 5 multifamily listings open in my browser tabs.

For each property, extract:
- Address
- Asking price
- Number of units
- Year built
- Price per unit
- Listed cap rate (if available)
- Any notable features or red flags mentioned

Organize this into a comparison table sorted by price per unit from lowest to highest.

Flag any properties missing key information.

5. Due Diligence Checklists That Build Themselves

What Anthropic said: “Claude asks clarifying questions upfront, then builds a user-editable plan before executing.”

What this means for you:

Tell Claude the deal type.

It asks what you need to verify.

Then it generates a customized due diligence checklist.

With responsible parties.

Deadlines.

Document requirements.

Try this prompt:

You are a real estate acquisitions manager helping me build a due diligence checklist.

Deal details:
- Property type: 24-unit apartment building
- Location: Dallas, Texas
- Purchase price: $3.2M

- Financing: Agency loan (Fannie Mae)

Before creating the checklist, ask me 3-5 clarifying questions about:
- The property’s age and condition
- Whether it’s occupied or vacant
- Any known issues disclosed by seller
- My team structure (who handles what)

Then create a comprehensive due diligence checklist organized by category:

6. Comparable Analysis From Messy Data

What Anthropic said: “Accuracy on internal evaluations improved 20%, efficiency rose 15%.”

What this means for you:

You can dump a messy CSV of recent sales.

Claude cleans it.

Standardizes the fields.

Calculates price per unit, price per square foot, cap rates.

And produces a formatted comp table.

This used to require multiple prompts and manual cleanup.

Now it handles the entire workflow.

Try this prompt:

You are a real estate analyst preparing a comparable sales analysis.

I’m pasting raw sales data from my market. The data is messy — inconsistent formatting, missing fields, different date formats.

[PASTE YOUR DATA HERE]

Please:
1. Clean and standardize the data
2. Calculate for each sale:
   - Price per unit
   - Price per square foot (if SF provided)
   - Cap rate (if NOI provided)
3. Remove any outliers or incomplete records
4. Create a formatted comparison table sorted by sale date (most recent first)
5. Provide a brief summary of market trends based on this data:
   - Average and median price per unit
   - Cap rate range
   - Any notable patterns

Format the final table so I can paste it directly into a report.
