HMO Management in Merton, London

Room demand in Merton (SW19) comes from the same people who already rent here: professionals, families and commuters. Merton is an outer south-west London borough, known for Wimbledon, and rents vary considerably within it, with Wimbledon itself commanding more than Mitcham or Morden further south. For a house share, that decides whether rooms fill: how quickly each tenant gets to work or study, and how well the shared kitchen, bathrooms and fire safety are kept.

Any house in Merton let to five or more people from two or more households needs a mandatory HMO licence from the London Borough of Merton. The fee is set by the council. Before turning a family home into an HMO, check with the London Borough of Merton whether an Article 4 direction covers the street, as that would mean a planning application. An agent that collects the rent is legally the person managing the HMO, so Caso checks the licence and the 2006 HMO Management Regulations before taking a property on.

Take a 5 room house share at the Greater London average room rent of £932 a month. The rent comes to £4,660 a month. A typical HMO management fee of 12% would be £559 a month; Caso at 9% is £419, a saving of £140 a month or £1,678 a year, all plus VAT. With three or more HMOs the Caso rate is 7%.

Caso manages each room as its own let, room by room: rent collected and arrears chased, four inspections a year, fire safety and certificate dates tracked, and the licence conditions kept. Tenants report repairs through a 24 hour maintenance line, and you get one monthly statement for the whole house.

You keep the HMO licence in your own name, with Caso named as manager. We are your managing agent only, so there is no rent-to-rent and no guaranteed rent. Rooms are filled through a local room-let agent at their fee, agreed with you first, with nothing added by Caso.
