You may wish to discuss your situation with a Nevada lawyer, so that you can get specific advice and information under Nevada law. In general terms:
You should be able to sue now, as you can reasonably calculate your damages based upon the remaining months of the lease.Quoting nickcindy
You may have a "duty to mitigate", which would involve demonstrating that you made a reasonable effort (successful or not) to find a suitable replacement tenant. (Note that if you can only find a replacement tenant by lowering the rent, you would be able to claim the differential as damages.)Quoting nickcindy
