The short answer
Estate management covers the administrative and coordinating side of ownership — documents, representation, liaison with advisors. Property management covers the operational side — maintenance, renovation oversight and technical supervision of the property itself.
What estate management covers
Administrative oversight, document management, local representation and coordination between the owner's advisors — lawyers, accountants, family offices and private banks.
What property management covers
Maintenance coordination, renovation oversight, technical compliance, and access, safety and security arrangements for the property itself.
Why the distinction matters
An owner who only has property management in place may find nobody is handling correspondence, renewals or coordination with their other advisors. An owner who only has estate management may find nobody is physically checking on the property. The two are complementary, not interchangeable.
Why most owners use both together
MONTEVIA provides both under a single point of contact, so an owner does not need to reconcile two separate providers — or worse, discover a gap between them.
