Use RealYield inside ChatGPT and Claude

How it works

1. 1. Add the connector

   In your assistant's settings, add a custom connector (sometimes called an app or MCP server) with the address above.

2. 2. Ask about a deal

   Give it a price and a rent, or a postcode. It calls RealYield and quotes the results.

3. 3. Sign in for Deal Check

   Only when you check a specific listing. The calculators work without an account.

4. 4. Check the numbers

   Results include links back to this site, so you can open the full calculation and change any input.

Things to ask

• “How does a 3-bed terrace at £180,000 renting for £1,100 a month stack up as a buy-to-let? I'd put 25% down at 4.5%.”
• “How much stamp duty would I pay on a £250,000 buy-to-let?”
• “I'm a higher-rate taxpayer with £12,000 rent and £5,000 mortgage interest. What does Section 24 cost me?”
• “Which areas in the North West have the highest rental yields?”
• “Check this listing for me: 3-bed terrace, M14 5RF, £180,000.”
