please help me to figure this out - I need to make a decision so

I have a new LLC and if I purchase a proplerty in Dec 2012, i will have a business loss (closing cost greater than rent), can this loss in LLC offset my personal income tax? Should I settle it in January 2013?  the loss will be over 10k.

according to web search, if the loss is Net Operating Loss, It can offset the other personal  income so I should close it in 2012, but if it is passive activity loss, it  can not offset personal income if I did not work for 500 hours on it.    Is my closing loss in LLC belong to net operating loss or passive activity loss?

Thanks in advance!
