The common practice is that whoever the broker is actively helping to find a place pays for it, and in most tenancies that is the person moving in. Some brokers split a smaller fee with the owner's side too, but property portals describe this as the exception, not the rule. Ask upfront who the broker expects to pay, so there is no dispute at move in.
The number
Tenant pays in the common case, an owner-side split is the exception, commonly quoted (NoBroker).
