The intent of this law, as indicated in a video by the sponsoring delegate was NOT to make housing providers have to comply with new operational standards or regulations.  This guidance document additionally does not cover other sources of funds, just HCVs.  

Where is the guidance for gift letters, savings accounts, corporate apartments, etc...

Additionally, determining an operational standard that does not provide for "rent" in total as defined by the VRLTA is not acceptable.  

How am I to treat everyone fairly in regards to income calculations if an entire segment of the population is provided with preferential treatment?

This guidance is incomplete and counter to the intent as stated by the Delegate.
