Photographing architecture at night?

I'm planning to go walking around my small, sleepy town and take some photos of the abandoned buildings and run-down houses late in the night, or very early in the morning. I'm using a dSLR, with a couple different lenses- among them a small telephoto, an 18-55mm zoom, a 28mm and 50mm lens. Does anyone who photographs architecture have any tips or advice for me? Answers are very much appreciated.
