Interactions with understandable coeffs

The previous model with the interaction term returned coefficients that were a little tricky to interpret. In order clarify what the model is predicting, you can reformulate the model in a way that returns understandable coefficients. For further clarity, you can compare the results to the models on the separate house age categories (mdl_0_to_15, mdl_15_to_30, and mdl_30_to_45).

taiwan_real_estate, mdl_0_to_15, mdl_15_to_30, and mdl_30_to_45 are available.
