Architect buys 5th property instead of helping sibling, family turns against him

A successful architect is facing backlash from his family after choosing to buy his fifth property instead of helping his sibling purchase a larger home. Despite already owning four properties, the man and his wife decided to purchase a new property in France, which would be their largest purchase yet and a place for them to retire. When the man's brother asked for financial assistance in buying his dream home, the architect refused and laughed it off, causing his family to turn against him. Although he later offered to buy his brother's house and rent it to him at no profit, his family was insulted and demanded that he simply give them the money. Now the man is left wondering if he was in the wrong for prioritizing his own dreams over helping his family. What would you do in this situation?
