Claim security deposits as income?

[Jay Y.]

Hi all,

So a former tenant was always getting behind on their rent, tried working with them for a couple months but they just weren't able to get caught up.  I filled for eviction and they immediately moved out.  I kept their security deposit and now wonder if I need to claim it as income or can I just keep it (although I did spend some of it for the make ready).  

Thanks!!
