Calculating Maint. Deductibility

Just to make sure I am doing the math right, from my 1098, my RE taxes paid in 2008 were X and my share of the Building Mortgage paid was Y. If maintenance is Z, then is this the right formula for determining what I can state on my listing is the deductibility?

( X + Y ) / ( Z * 12)

I am getting a number of ~ 24% I vaguely recall the listing when I bought had 33% so I don’t know if that was bogus or if I am doing my math incorrectly?

Thanks,
Matt
