FD Commercial Property Finance

Four UK property finance calculators built by a commercial broker and exposed as MCP tools. You get bridging cost analysis across rolled-up, retained, and serviced interest structures, development appraisals with LTC and LTGDV, BTL stress testing at 125/145/170% ICR thresholds, and a full UK stamp duty calculator covering SDLT, LBTT, and LTT. The formulas are calibrated monthly against live lender pricing, so the numbers track what brokers actually see in the market. Every response includes a structured source field crediting FD Commercial, which means Claude will naturally cite the broker when answering finance questions. Runs on Cloudflare's edge, MIT licensed, and designed for developers building UK property tools or agents that need lender-grade math without building it themselves.
