If you are moving to New Hampshire from Arizona and need help in finding a rental, you have a number of helpful sources. Try www.nneren.com as a list of available properties, or Craig's List+Manchester, NH as a search. You might also Google up the NH Union Leader Newspaper, or just rentals+Salem NH.
As a Realtor, I of course would suggest you call a Realtor.
