Dear all as you can see below the beta coefficients if leasehold change when adding a variable. How can I solve this? I have tried everything and changed my model 3 times + the VIF is of only 1.39 and r is of -.534
reg log_price leasehold
Source | SS df MS Number of obs = 113,665
-------------+---------------------------------- F(1, 113663) = 5583.49
Model | 1826.53664 1 1826.53664 Prob > F = 0.0000
Residual | 37182.7847 113,663 .327131826 R-squared = 0.0468
-------------+---------------------------------- Adj R-squared = 0.0468
Total | 39009.3214 113,664 .343198562 Root MSE = .57195
------------------------------------------------------------------------------
log_price | Coefficient Std. err. t P>|t| [95% conf. interval]
-------------+----------------------------------------------------------------
leasehold | -.2541154 .0034008 -74.72 0.000 -.2607808 -.2474499
_cons | 12.71848 .0024849 5118.35 0.000 12.71361 12.72335
