We have always taken before pictures. Helps tremendously. Also, if a Guest has done damages and not notified you during their booking, then this is when it sometimes becomes a larger issue. One way we have eliminated nearly all damage issue is in requiring the guest to purchase the damage insurance. Should there no damages, this deposit amount is fully refundable. Any reputable Guest doesn't mind the extra charge. If and when you do get a guest that states they don't want to pay for the damage insurance,...red flag so we recommend decline the booking. And we never negotiate the cost of damages with a guest. At the end of the day, it's the damage, plus your time, plus the possible loss in subsequent revenue should the damage cause your property to have to be shut down while repairs are underway.
When we first started, we had one group that caused over 1K in damages and it was before we had the required insurance. We submitted the physical repair costs to the group and they paid, but then the booking platform took a commission out of the payment. So basically, we lost $$ on the damages caused. Hard lesson learned.
