Greetings. In preparation for colder weather, would birds prefer I clean out bird houses now, or wait until spring? I don't know if the existing nest material is a deterrent or a positive. Thank you.

Assuming the birds are no longer using the bird houses, it is a good idea to clean them out because they are often a haven for bird mites and other insects.
On the other hand, birds need shelter in winter, especially during storms and bitter cold. At those times, they may seek shelter in a birdhouse, which can be fairly snug because of all the nesting material left there. This is especially important if there are not a lot of evergreens trees or shrubs nearby, because these plants provide some shelter when deciduous trees have lost all of their leaves and are no protection at all.
