I actually just got a text back from the guy, lol. Couldn't be bothered to respond 3-4 months after, but now he will? I'm still not all that optimistic. Again, a gut feeling tells me he's going to say "Well, we needed this much for carpet cleaning (there was no carpet), and general cleaning, etc, etc. Your deposit return is $0.17."
We'll see, I guess.
The apartment I previously moved out of, he was part owner of (which I didn't know at the time), and they had me pay $200 to get the carpet cleaned, and then charged me another $150 for carpet cleaning after I moved out...
