If you're the owner of a Domoreport, you can share with up to 9 additional people. It can be with anyone with an email address. Typically reports are shared with:
Anyone who is also purchasing the home
Significant others
Realtors
Property managers, if you're a landlord
Less typical, but sometimes it also makes sense to share with:
Contractors
Mortgage brokers
Insurance agents
Other family members
