Have you written any articles about shooting for stock on lifestyle, community and amenities of a city or neighborhood? I charge by the hour to shoot those things if I don't have them, but would like to offer "stock" images to Realtors with listings where the images may apply. Wondering how to charge for that.
Offering community photos for the major neighborhoods you shoot in is a great idea. I don't think most listing agents do a very good job of selling the neighborhood.
To me, it seems like a better approach to use your library of neighborhood photos as another reason for Realtors to choose you as their real estate photographer. Offer 5 or so neighborhood photos for all listings you shoot in certain neighborhoods where you do a lot of shoots. Yes, there have been some real estate photographers that sell these image separately but it is unusual.
An even stronger way to sell the neighborhood is with a short video. As an example here is a Maui lifestyle video that Travis Rowan shot for Tom Tezak. Although this is not something you are going to sell to low-end listing agents but it shows the strength of video for selling the neighborhood or area. The main point here is that selling the neighborhood is key to selling a property and you do it with both stills and video. You need to promote this idea to your clients. Not all listing agents realize how important selling the neighborhood is.
