How to locate the Listing Agent:

[Jessica Russell]

As I'm sitting home late on a Friday night, after Real Estate Office hours, I am finding that I struggle with finding the name/number/email of the listing agent on houses I'm interested in placing an offer on. Realtor.com only shows the Brokerage name, same on Zillow and Trulia. I'm not a licensed agent so do not have access to the MLS. How do I get the name of the listing agent for properties other than driving by it?

Thanks!
