Five numbers every landlord should watch

Billed against collected

The gap between them is your arrears.

Arrears by age

Debts more than 60 days old are the hardest to recover.

Vacancy

Empty days cost rent. Track how long units sit empty.

Repair spend

Compare it to rent per property to spot a building that costs too much.

Paid on time

The share of tenants who pay by the due date shows whether your routine works.
