The 7:40 call from a building super is the one you cannot send to voicemail
Your best inquiries often arrive outside the hours a small office covers, and they do not call twice.
Supers, porters and managing agents call early, from a building, with a problem that started overnight. Homeowners call late, from a couch, after the cold room finally annoyed them enough. Neither window is well covered by a nine to five phone.
Measure answer rate by hour before changing anything. Most shops discover a specific band, usually early morning and mid evening, where a meaningful share of calls go unanswered and never return.
Fix coverage cheaply first. A live answering service that takes structured details, a text back that fires within minutes on a missed call, and a clear rule about who calls back and by when. Speed of first human contact is the single most controllable variable in this business.
Track callbacks the same way you track calls. An inquiry that was answered by a service and never called back is worse than a missed call, because you paid for it twice.
