A percentile tier is a relative rank inside a city pool, not an absolute-score cutoff. Choose one per city and lens to control shortlist and alert volume.
Start from the city tiers
Top tier means percentile 95 or higher and uses green. Strong means percentile 80 or higher and uses amber. Everything else is grey. The colour never comes from an absolute score; it comes only from the percentile.
Use the preview
The tier editor shows how many active listings in the city currently sit inside Top or Strong before you save. Zip filters can narrow what you view without changing the city pool used for the percentile.
Different lenses, different lines
Each lens has a different score distribution. Percentiles make the tier comparable without pretending an absolute score carries the same meaning across strategies. Set each lens separately.
Alerts follow the percentile tier
Tier alerts fire after a check when a property enters the saved city tier. Strong is broader than Top, so it produces more matches.
Revisit monthly
Cities change with the season and with your pipeline. Review which tier produced useful research and adjust between Top and Strong. Do not tune from an absolute score cutoff.
