Yes, you can rent it out and take a loss at tax time on it.
Another option would be to put some $$ into it in some form of "office" type expansion or such. Then you can get a bigger tax break there as well. I helped my ex do this as he built an addition of 30'x40' onto the back of his which was a complete master bedroom, master bath, den and kitchen expansion. He wrote it off as his studio. (he was an artist). Doing this will not cut the rate of loss down, but it will reduce your taxes a little and thus add improvements to the house that will drive up the price when it comes time to sell.
Another option would be to rent it to someone at the loss and get "benefits" from them to cover the loss. Like lawn care at your additional properties.
When I moved here, I bought two corner condos side by side in a building. 2 bedrooms, 1.5 baths in each... floor plan was a mirror to each other (rooms reversed). I knocked the wall down between the two and combined the two units. I ended up with a extra large roommate style unit, 2 bedrooms with huge sitting area (which had previously been the second bedroom in each unit), extra large living room (almost loft style it is so big), huge kitchen, dining room, second dining room became a den/tv room, one half bath, the second half bath had the wall knocked down and the plumbing used for a wet bar, and more changes... But when it was all said and done, I still only had ONE unit. Which greatly reduced the taxes that I was previously paying for TWO units. And my rent is more than I would have gotten on two average units as well.
