Find out if house is vacant

[Jeff Fairchild]

Ok, so I drove around and wrote down a list of a bunch of houses that looked like they might be vacant. I didn't get out of my car, so I don't know whether some of them were just at work. Is there a way to look online to see if the house is vacant?

Also, is there a website I can go to to type in an address to see if the house is listed with a realtor?
