How do I analyze an Airbnb investment with AI? (BNBCalc MCP)

Which analysis should I ask for?

The BNBCalc MCP server runs the same four analyses as the BNBCalc Calculator, so pick the one that matches how you'd make money from the home:

Every analysis also needs the address, plus the bedrooms, bathrooms and how many guests it sleeps. For example:

Run a buy analysis on 123 Main St, Austin, TX 78704: 3 bed, 2 bath, sleeps 6, $450,000 purchase price, 25% down, 7% interest over 30 years. What's the monthly cash flow and cash-on-cash return?

If you leave out the loan on a US buy analysis, BNBCalc assumes 20% down at 5.1% interest over 30 years, and the expenses always start from BNBCalc's standard assumptions for the country, not from presets you've saved in the app.

What does the analysis return?

The same numbers you'd see in the app, worked out the same way:

• the revenue estimate, nightly rate and occupancy, with what the nearby comps actually earned;
• operating expenses, the mortgage or rent, and the monthly and yearly cash flow;
• the return metrics for that analysis type, such as cash-on-cash return and cap rate on a buy, the payback period on a rental arbitrage, or your commission and the owner's payout on a co-host deal;
• the 20 nearest comps, with how many were found in total;
• a link to a report you can share.

The analysis is saved to your account, although it won't appear in your Properties list. To come back to it, ask "List my saved BNBCalc analyses" or "Open BNBCalc analysis [ID]", which are both free.

How much does an analysis cost?

A full analysis costs $0.20. You can also ask for AI comps, which compare nearby listings' photos and amenities with your home and keep the closest matches, or AI expense estimates, which tailor the costs to the property, and each one that completes adds $0.10. So an analysis with both costs $0.40 at most. With AI comps, the analysis's revenue becomes the average of the AI's closest matches instead of BNBCalc's starting estimate.

AI comps only work on US properties with enough listing photos. If an AI step doesn't finish, it isn't charged, and you can ask for it again later on the same analysis for $0.10.

How do I compare two deals or two strategies?

Ask for both in one prompt, and the assistant runs the analyses side by side:

Compare buying 123 Main St, Austin, TX 78704 (3 bed, 2 bath, sleeps 6) at $450,000 with 25% down at 7%, against renting it for $2,800 a month and running it as an Airbnb. Which one makes more per dollar I put in?

Running both costs $0.40 before any AI steps, since each analysis is $0.20. Make sure to keep the bedrooms, bathrooms and guests the same in both, or you'll be comparing different homes.

Can I trust the result?

Treat it like any BNBCalc analysis: a starting point built from comparable listings, not a guarantee. Since the MCP server returns BNBCalc's starting estimate, its revenue can come in lower than the app's figure for the same address, and it doesn't know your home's condition, design or how well it'll be run. Before you commit to a deal, check the comps behind it and confirm the short-term rental rules for the address.
