Families face mounting pressure to consolidate wealth across generations while estate planning remains fragmented and vulnerable to legal disputes. The challenge: knowing which investments deliver legacy value versus those that drain capital. Moreover, multigenerational living is becoming more common, with 25% of children sharing homes with parents and grandparents at some point. Exterior expansions and material upgrades outperform interior renovations in cost recovery—a critical distinction for families planning multigenerational wealth. Deferring estate planning until after death can create ownership disputes and family conflict in legacy properties.
