Common Mistakes to Avoid
Making investment decisions based solely on metro-level data without neighborhood analysis.
Consequence: Buying in a declining neighborhood within a growing metro results in underperformance.
Correction: Always analyze at the census tract or zip code level in addition to MSA-level metrics.
Relying exclusively on data without physical neighborhood inspection.
Consequence: Missing visual cues about neighborhood trajectory such as deferred maintenance or new development activity.
Correction: Supplement data analysis with on-the-ground observation at different times of day and week.
