Deal Memo MCP
An MCP server that performs real estate underwriting for US residential properties. It accepts an address and strategy to generate automated value estimates, rent projections, comps, cap rates, cash-on-cash returns, DSCR, and red flags, outputting a one-paragraph analyst memo based on RentCast data.

realestate_deal_memo — Deal memo
Advertised destructiveOpen-world
Underwrite a US residential property from its street address for a rental, flip or hold strategy. Pulls the property record (owner, last sale, taxes, HOA), the automated value estimate with sale comps and the long-term rent estimate with rental comps from RentCast, then computes NOI, cap rate, cash-on-cash, DSCR, GRM and break-even occupancy from stated assumptions with deterministic math (plus 70%-rule, profit and ROI for a flip; a multi-year exit projection for a hold), lists red flags with a pass/review/fail screen, and adds a one-paragraph analyst memo. Returns {data, sources, as_of, confidence, notice}. Not financial advice: verify before acting. Paid: $0.75 per call; without credit you get a PAYMENT_REQUIRED result. Set sample=true for a free example response.

}realestate_lookup — Property lookup
Advertised destructiveOpen-world
Fetch one RentCast record for a US street address. kind=property: characteristics, owner, last sale, tax bill, assessment, HOA and sale history. kind=value: automated value estimate with a low/high range and the sale comps behind it. kind=rent: long-term rent estimate with a range and rental comps. One upstream call per lookup; use realestate_deal_memo when you need all three plus the underwriting. Returns {data, sources, as_of, confidence, notice}. Paid: $0.10 per call; without credit you get a PAYMENT_REQUIRED result. Set sample=true for a free example response.
