Sounds like a marketing tool to get a foot in the door for other estate-planning services, possibly leading to selling investments like annuities.  What makes you think the place is not already community property?  Some states have added "community property with right of survivorship" as an alternative to "joint tenants with right of survivorship," because some legislators were concerned that IRS might change its mind about joint tenancy being consistent with community property.  Maybe you have some source that indicates that has happened.  Or maybe you are looking for a solution to a problem that doesn't exist.
