It has been mentioned that Brookfield and CH Estates were selected due to affordability.
Another thought that I just had is that BOTH neighborhoods (and more specifically the homes themselves) have convenient access to public bus transportation which could easily be utilized by potential staff to the homes.
While we have discussed employees being dropped off and picked up, etc. it hasn't come up that this also could be a possibility with NJ Transit buses being so readily available at the light at Berlin & North Valleybrook Road. Like the Brookfield Academy students ongoingly walking through the neighborhood, this would create an opportunity to have some to many employees doing the same.
