Hi Tony,
Congrats, you're about to start an exciting journey 
In order to enjoy it and perform your implementation as smooth as possible I would recommend to contact local SAP office, local SAP Service Partner(with existing SAP Real Estate practice) or SAP RE-FX expert. This will guarantee quality of information and documentation provided, and save you a lot of resources and efforts.
PS. Please keep in mind that SAP Real Estate solutions have strong country and industry specifics/differences.
