Hmm, I see your point, but that's being naive. I'm asking the question because a maintenance worker came over and we started discussing my move-out process and I asked if I should worry about the carpet. He informed me that the carpet is going to be replaced after I move out anyway since they usually replace the carpet after 2-3 years. He's been working on the property for over a decade so I assumed that his word had some credence. However, when I asked the leasing office, they informed that the carpet has a lifespan of up to 7 years. So, if the carpet is at 5 years of a supposed 7 year lifespan, then what is my liability? 2/7 of the cost of the replacement? I understand that the gross cost of the replacement or associated cleaning would be greater than rather pursuing that on my own (i.e. via independent carpet cleaner for ~$100), but how is that not covered as standard carpet cleaning by the LL? The point that I'm trying to make is that if the carpet has potentially already reached it's depreciable rate, then why should I be liable for carpet cleaning (https://www.irs.gov/pub/irs-pdf/p527.pdf)? I'm looking for hard facts.
