Also, I would run the #s ahead of time (treat it as if you will move out in a year or 2) and see if it cash flows once you buy the next one (and depending where it is... it could potentially be a long-term, short-term, mid-term... pay attention to HOA rules if they exist when determining asset class).

Really just more curious than anything, as to how many bookings are last minute (week of) vs a month+ ahead of time?
