I talk to Linda Wong Property Manager extraordinaire.  Today she takes me through the process of how she conducts rental appraisals; tips for a landlords and tenants.  She explains the two different types of property rental appraisals; one just from photos and the preferred method by visiting the property and assessing the flow, the sun, the location, the condition, damage and things that need to be done.  Sometimes these things can't be seen by photos alone.  
Whether you are a tenant or a landlord make sure you find out what you should be doing; to save you hassle, time and money down the track.  
Landlords and tenants should listen up to this knowledge.
