Actually a lot of the info you'd get from an operating statement (gross rent, expenses, NOI, etc.) is available on many listing websites like Redfin and realtor.com, albeit not as up to date as the MLS and not always accurate but that goes for all data provided by listings.Regarding MLS access: it is protected carefully with various methods such as keystroke tracking, IP address, simultaneous login etc. and agents can get in a lot of trouble for sharing their login info, which is good because within the massive database is a lot of private info that can be dangerous in the wrong hands like lockbox and security system codes.
