What Does Section M Cover in ISIC Rev. 5?

Section M in ISIC Rev. 5, UN Statistics Division, covers real estate activities. This includes buying, selling and letting real estate on own account, and real estate activities on a fee or contract basis, such as agency, brokerage and property management for others. It also includes intermediation for real estate, described below in its own guide. Section M is separate from Section L finance and insurance, even though mortgages and property investment often involve both.

Three ways to touch the same flat

Section M becomes intuitive once you imagine a single flat and three different firms touching it. A landlord owns the flat and lets it to tenants. An agency markets the flat for an owner and earns commission on a sale or a letting. A developer builds the flat in the first place. All three touch the same housing market, and yet ISIC Rev. 5, UN Statistics Division, places only the first two in Section M, because the third is construction, not real estate activity. That trio is the fastest route into the section: ownership and service belong here, building does not, however closely the three cooperate on a real street.

The full scope follows that logic. Real estate activities on own account include letting property owned by the unit and buying and selling real estate on own account. Real estate activities on a fee or contract basis include agency, brokerage and property management for others. Intermediation for real estate, including class 6821 in ISIC Rev. 5, UN Statistics Division, covers bringing parties together for a transaction without owning the property. Property management for others, where the UNSD entry places it here, completes the picture: managing a building for its owner is service work, not ownership, even when the manager’s name is on the door.

Own account first: rent and sale profit

A landlord that owns flats and lets them to tenants illustrates real estate on own account in its purest form. The landlord’s income is rent, its asset is the flats, and its fortunes follow occupancy and rent levels. Buying and selling on own account follows a parallel logic: a firm that buys flats, holds them, and sells them later keeps the difference between purchase and sale price, less its costs, and that difference is property profit, not a service fee. Both patterns share the ownership test: the unit’s money is tied up in the property itself, and the property’s value, not a client’s instruction, drives the return.

That ownership test is also what keeps mortgage lending out of Section M, even though a mortgage finances the very same flat. A bank that lends to the buyer earns interest, holds a loan rather than a flat, and belongs in Section L. A lawyer who conveys the title earns a legal fee and belongs with legal services. An architect who designed the building belongs with professional services. Section M is not a heading for everyone involved in housing; it is a heading for owning, dealing, managing for others, and intermediating, and the other participants keep their own headings.

For others: commission, management fees and matches

An agency that markets flats for owners, arranges viewings and earns commission on a sale illustrates fee or contract work, the second arm of the section. The agency never owns the flats, never receives their rent as an owner, and never keeps their sale price; only the commission stays with the agency. A manager that runs flats for owners, collecting rent on their behalf and arranging repairs, illustrates the management arm: the rent belongs to the owner, the fee belongs to the manager, and the building stays the owner’s asset throughout. An intermediary that matches a landlord with a tenant, or a buyer with a seller, and charges for the match illustrates the third arm, class 6821, where the service is the connection itself rather than marketing or ongoing management.

Construction of buildings is the outside neighbour to hold in mind most firmly, because developers and landlords are so often the same group in commercial life. Architectural design of buildings, in professional services, is the second neighbour, and legal conveyancing as a legal service is the third, with mortgage lending by a bank, in Section L, as the fourth. Where a group does several of these at once, the principal activity test used by statisticians and the wording in the UNSD structure decide the placement for each unit, not this guide, and each unit in the group may legitimately carry a different section.

Checking a Section M placement before using it

Verification here means reading, not guessing: locate this activity in the UNSD structure, note the exact wording at each level, and check any exclusions noted there, because the difference between owning, managing, matching, building and lending is written into that wording. This guide is statistical classification only: it does not determine any reader’s code, principal activity or registration, and the national statistical institute or business register that holds the record should confirm a code before it is used in a return or a register.
