Hi Mtnrose! Carol here at Trulia. At this time we do not have a feature enabling you to sort your homes by city. I have forwarded your suggestion to our specialists.
As we are continually working on improvements, I encourage you to continue notifying us of ways we may improve our services to better meet your needs. Feel free to send us any further insights or inquires.
If you have additional questions, please contact us at http://www.trulia.com/help/ask/ or call Customer Service at 1-888-466-3501.
