One of the primary services that any property manager performs is providing a level of separation between the tenant and the landlord. The landlord should avoid any direct contact with the tenant. Important: avoid sharing your contact information with the tenant.
Tenants often ask to bend rules, break lease provisions or make other special requests. The property manager knows the rules and knows why the rules exist. A tenant can catch an uniformed landlord at a moment of weakness and the landlord can grant a request that is counter to the landlord's interests.
The result of acceding to a seemingly simple request can be disastrous. Furthermore, once the tenant knows there is an opportunity to appeal, the tenant will take all matters to the landlord, which cost the landlord time and effort.
Tenants can also use contact to build a personal relationship with the landlord. Personal feelings can make it much harder for the landlord to make objective business decisions in a impersonal manner.
Additionally, the tenant can hound or harass a landlord at unreasonable hours or with unreasonable requests. We're paid to be your protect your interests. It's harder to do that job when the tenant is going to ask you to second-guess our work.
