Hi Jeff,
The homes you see here are put here manually by realtors. Or they list them on another website and they are automatically pulled from that website to this one.
For all the listings in every state you can go to realtor.com and you'll see the homes you drove by on that site.

Hope this helps!

Jeff,

Unfortunately not all local listings are inputed into trulia unless a specific company and/or agent decides to do so. Some of it is through IDX (information data exchange) however this system isn't perfect. Also, if an address is not disclosed, the marker for that property will show up in the middle of the zip code it is located in.

Hope this helps. To find out more information on the homes you have driven by please visit the website below. Just do a local search (of all homes listed) and hopefully you will find the answer you are looking for (price, beds, baths, etc.).
