Might try the local fish wrapper as well. I cant think of other ways rentals are advertised off the top of my head. But it cant be too hard to cover most of the bases. Tell us what you discover.
PS: I’ve run ads on Craigslist posting what I want and what I am willing to pay for it, with great success. But put it in the section that’s trying to rent the houses, not the “wanted” section. For some reason, it works a lot better to put it where the ads are posted for rentals available.
