Lame financial statement?

[Ryan Moore]

I am under contract to purchase my first multi family rental property here in Phoenix. I asked for the financials and was given a statement for the 2015 year. Problem is that it only has July through October. And just for those months that shows the net operating income of -11,000. The owner has had the property for almost 3 years. I would assume I can expect more than just three months of income/ expense statement correct? Is this pretty lousy for the seller to give me just this much info?
