HMO legal definitions in different parts of the country, an HMO — House of Multiple Occupancy — is generally considered to be a property let to five or more unrelated people (two or more in Scotland), rather than to a single family unit. The residents each have their own bedroom but share a communal kitchen and bathroom(s). Again, definition varies around the country and also among lenders but a “multilet” is generally considered to be a property with shared facilities let to less than five occupants.
Portfolio property finance: A property portfolio is two or more investment properties.
