This isn't meant to be flip, but it's one of those two.
Seriously, it depends upon your county and if they collect taxes in arrears (after the fact) or by prepayment (ahead of schedule). Look at your HUD I from your purchase........the higher the number of months collected (as high as 14 months), the better the odds it's prepaid. Lower amounts, 3 or 4 put the odds in favor of being in arrears.
What county and state? Maybe someone will know.
