How to optimize for real estate agents who have company web pages they can't access?

[randy]

I hear from a lot of real estate agent frustrated because their website is on a company-run page to which they have no access. And sometimes it displays the corporate main office address instead of enabling agents to localize it for their own office.

Anyone have suggestions on local optimization for agents who don't control their web pages? Create a separate site for localized content? How would you deal with NAP consistency on citations? Any thoughts or shared experiences are appreciated.
