When I meet with new investors, this is often a major part of the discussion.  Who is going to manage the property?  Are you going to collect rent, but have someone else do the maintenance. Alternatively, maybe you see this as a hobby and want to do all the maintenance.  Other investors see this as a passive investment and are not interested in even knowing the names of their tenants.
