There are three aspects that affect people's fortune: 1. Bazi; 2. Yangzhai; 3. Yinzhai.
From the picture, both the old house and the main house are heavily obscured by bamboos, trees, kitchens and bathrooms. A Yang house needs to be bright, but a house with too much Yin energy is not good. The graphics of trees and bamboos in the yard of the old house are like a big knife coming towards your home. Moreover, in the West, where the knife is metal, (the big trees 1, 2, 3, and 4 are like inlays) it is particularly unfavorable. When the new owner doesn't have a house, the entire yard belongs to your house, so it doesn't matter. Now I don't know whether the old house is taller or the new house is taller. The yard should be flat, and the foundation of the house should also be flat. It would be best if economic conditions allow for timely renovation of the old house to make it consistent with the new house. Even if there are no conditions, the old house should be demolished or repaired. It must not be left dilapidated. The dilapidation of the house itself means that the family is not prosperous. And the old house is the foundation.
