Mandatory HMO licence required

England: a mandatory licence applies at 5+ occupants from 2+ households. Many councils also run additional or selective licensing for smaller HMOs, and Article 4 areas need planning permission. Always check with your local authority.

Not financial advice. For educational purposes only. HMO costs, room rents and licensing rules vary widely by area. Verify figures and local licensing with your council, broker and accountant before committing.

HMOs are a net-yield game. A 14% gross yield can become a single-digit net once you add landlord-paid bills, 12%+ management, voids between tenancies, and licensing. The number that pays your mortgage is the net yield and the monthly cashflow, not the gross.
