Multifamily Demand-Handling Voice Agent using CrewAI and VAPI Integration
Multifamily operators struggle with lead conversion due to slow response times and inefficient inquiry handling. Build a multi-agent CrewAI orchestration with VAPI voice interface integration that handles prospective tenant inquiries and schedules property tours with under 2-second response latency.
What you are building
Design a collaborative CrewAI agent ensemble paired with VAPI real-time voice streaming to capture prospect preferences, check lease management DBs, and book automated tours.
How work is evaluated
Tests CrewAI task completion for extracting tenant preferences and booking tours via simulated VAPI call payloads.
Datasets
Public datasets, plus the private datasets you have access to.
How submissions are scored
Qualification Evaluation
Checks if qualification decision matches financial parameters.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
Tour Booking State
Verifies that tour booking succeeded without errors.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
intent_extraction_accuracy
Accuracy of unit target and timestamp extraction from call transcript • target: 1 • range: 0-1

Learning goals
Configure CrewAI agents with dedicated roles for lead intake, lease database lookup, and tour scheduling.
Integrate VAPI Webhooks to stream audio transcriptions to the agent ensemble in real time.
Enforce tenant pre-qualification parameters (income-to-rent ratio, move-in timeline).
Achieve zero booking conflicts across automated scheduling calendar endpoints.
Resources
Dataset of 80 real estate inquiry call transcripts with annotated prospect financial attributes, preferred move-in dates, and target property specs.
Challenge setup
Tests CrewAI task completion for extracting tenant preferences and booking tours via simulated VAPI call payloads.
Challenge input
JSON transcript event from VAPI
CrewAI
Mandatory framework for agent team orchestration.
VAPI
Required interface for voice transcript input and audio stream integration.
