01
Local lens
Why block-by-block context matters
Property fundamentals are only part of the story. Access, neighborhood momentum, and nearby demand shape the decision.
02
Investor practice
A score should start a review—not end it
We pair eligibility and confidence with the assumptions behind them, so a promising number can still be challenged.
03
