Help interpreting P&L statement

[Brian H.]

Looking at a four-plex as my first multifamily venture. I have the rent roll and expenses for the past three years and have a question about an item in the expenses column. It's entitled "Inv. Fixed Asset" and is one of the larger expenses for each year ($1431, $1465 and $2299 for 2009, 2010 and 2011, respectively). Can anyone shed light on what this might encompass? I would ask the property manager but she's out of town for the holidays so I thought I'd pose the question here.
