A house to HMO conversion turns a single-family home into a house in multiple occupation: a shared home for unrelated people with private bedrooms and shared kitchen or bathroom space. Landlords in Brent (HA0 and HA9) usually come to us with a council letter, a fire risk assessment or a house they have just bought. We price from whichever you have.
