OLS with White heteroskedasticity-consistent (robust) standard errors in parentheses; *** p<0.01, ** p<0.05, * p<0.1. Three models: full sample (n=101,598), villas = detached houses (n=72,198), edificios = buildings/apartments (n=28,993). Table 3 (p.13) gives environmental, neighbourhood and location coefficients; Table A1 (pp.19-20) continues with structural/material coefficients for the same models. Age enters as log(age) per Table 1 although Table 3 prints 'antigüedad'. Accidents and robberies are ordinal frequency indices from -3 (least frequent) to 3 (most frequent). NO2 in ug/m3 (Figure 1); noise in dB. Prices are cadastral appraisals, not transactions. Decimal commas in source converted to points."
