Rental yield
What the property actually returns
Annual return with fees, service charges and vacancy between tenants taken into account — the things usually lost in a back-of-the-envelope calculation.
An investor who has already seen several properties will check the figures. So the report shows not just the result but what it's made of.
After costs
Service charges and fees are included, not set aside.
Vacancy
The gap between tenants is built into the model.
Checkable
The client sees the components, not just a headline percentage.
