HMO Valuation

GET/valuations/{uprn}/hmo

HMO-specific valuation: sale value as an HMO, gross rent per-room, implied yield.

Overview

Built on live SpareRoom room-rent data and regional HMO market multiples. Returns a point sale value plus low/high band, gross rent broken down per room, and the implied gross yield.

Why this endpoint exists

No mainstream AVM covers HMOs — they're priced off room count, not bedroom count, with comparables on SpareRoom rather than Rightmove.

Building this yourself means scraping SpareRoom, mapping rooms to LHA bands, and inferring EPC-derived room counts. One endpoint does it all.
