It is unclear what you mean by conditions, and the facts here will matter a lot. Your tenant has an obligation to abide by the terms of the lease. If she moves out and stops paying you have a claim against her for non-payment, which is subject to a requirement for you to act reasonably to mitigate or reduce your damages.
You should try and rent it out in the manner you would normally do so. After all, any money you collect is money in your pocket and not money you have to chase from a former tenant. Your former tenant does not get to reduce her potenial liability by the hypothetical value of the property, but if you rent for an unreasonable amount she could claim you were not correctly mitigating your damages. It would be very advantageous to talk to an attorney to advise you on this issue, and how to proeceed so that you can minimize your time and expense in collecting under the obligations on the lease.
Your tenant cannot breach a legally binding lease. You can ask any amount of rent as you chose even they do not match with the comps. There is no defense to breach of lease as I can see in the given circumstances.
