Here is the Dona Ana County Parcel Viewer service.  You can zoom in on parcels in Las Cruces by using this map.  Once it loads click on the icon of the blue binoculars then type in the address.  It should bring you right onto the property.  Remember these photos were taken in 2004 so new homes will not be depicted but the parcel borders will be clearly shown.  Use the icons of the magnifying glasses to zoom in and zoom out at the top of the page to get a better feel for the area.  Lastly, Enjoy.  This is the best site to see exactly what the home or lot looks like.
