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 Northampton (NN1, NN2 and NN5) 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. Northampton has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.
