- Determine net rental yield
- Compare yields across neighborhoods
- Identify high-yield opportunities
Neighborhood Growth Analysis
Identify emerging areas before prices surge:
Data requirements:
- Historical price trends by neighborhood
- New business openings
- Infrastructure investments
- School performance improvements
