Opening New Rentals

I just realized something yesterday. The humans have a whole attic that they really aren't using, except to store the Christmas decorations, and the flowers that they lag to the cemeteries every year while Betsy runs wild and torments the mountain bears. If I could install a hole up there, I could rent out the space to any number of birds in need of winter lodging. I'm sure that there are tons of them who are tired of that long commute south, after all, and who would love to nest in a nice attic for the winter. Does anyone have suggestions for how to advertise? I'm going to tell my woodpecker tenant to invite all of his friends.
