Difference-in-differences with property and year fixed effects: the only characteristic-related coefficients are treatment-by-post interactions for distance bands to Elizabeth Line stations (mapped to transit_distance with x_transform 'other'); no structural characteristics are estimated (time-invariant, absorbed by property FE). Macroeconomic controls (inflation, interest rate, GDP growth) and the RE property-type coefficients quoted in text (section 5.4) not extracted. No significance stars; clustered SEs at property level in parentheses; p-values recorded only where stated in the text. Suitable for the transit/infrastructure capitalisation subset only, not for structural pooling."
