For -9 to "seem" off you need to become a statistician and look at plots and summary statistics: residuals vs. fitted values. Basically the only way that number is off is if you ran the model incorrectly, which is a software debugging question. | |

Also, I understand that the "meaning" of the intercept is useless in terms of units of price. Yet the magnitude of it seems large compared to the value of the other terms. | |
