Steps
Once connected (see setup above), use the Real Estate Data tool:
- Give Claude the property address, asking price, and your financing assumptions — deposit, mortgage rate.
- Ask Claude to run `rental_analysis` via the real-estate tool for the address.
- Ask Claude to run `property_valuation` to cross-check the asking price.
- Have Claude calculate the net yield based on the rental data and your cost assumptions.
- Ask Claude for a clear recommendation on whether this property is worth pursuing at the asking price.
Example Prompt
Try this with Claude using the Real Estate Data tool
Use real-estate to analyze the rental yield for 15 Oak Avenue, Leeds, listed at £180,000. Assume a 25% deposit and a 5.5% mortgage rate. Get the rental analysis and valuation, calculate the net yield after typical costs, and tell me whether this stacks up as a buy-to-let investment.
Tips
- Always model net yield — after mortgage, management fees, and maintenance — not gross yield.
- Ask Claude to compare the yield to the local market average so you know if this property is above or below par.
- Include your target net yield in the prompt so Claude can give a clear pass or fail verdict.
