This is our first year renting our condo. For those of you with more experience under your belts, when do your rental inquiries and reservations start coming in? Do people tend to reserve months in advance, or is it typically closer to the time they intend to visit? Or a mix? On another train of thought--what do you do in the way of follow-up after someone's rented from you? A thank-you e-mail? Any follow-up a year later to encourage them to reserve again?
