Which of the following are common covenants by landlords and managers?

The correct choice highlights a key responsibility of landlords and property managers: the obligation to collect and account for service charges. This task is essential for the financial management of the property, as service charges are typically collected from tenants to cover communal expenses such as maintenance, landscaping, and cleaning of shared areas. Properly managing these funds is crucial for ensuring that the property is well-maintained and that tenants receive the services they are paying for.

In contrast, while paying taxes and repairing or decorating the property might seem relevant to landlord responsibilities, they can be more situational and may not universally apply as covenants in all lease agreements. Furthermore, allowing unrestricted renting of the property is generally not typical of landlord covenants; most leases will have specific restrictions regarding subletting and transfers. Thus, collecting and accounting for service charges stands out as a common, expected duty in property management that directly impacts tenant relations and property upkeep.
