I have had a lot of bad luck this year and had multiple thefts. My car got broken into (laptop, headphones, keys stolen, broken window) and I had another theft of a bag with a bunch of clothes and some small electronics. Since I am a student with a small income the thefts probably exceed 10% of my AGI. How should I estimate the damages? Can I just give rough round estimates or do I have to calculate the exact depreciation. If so how do I do this?
