However, the advantage for the tenant in moving out is that this will make the court more likely to eliminate the rent completely for the time during which the tenant vacated. Also, if you have a strong case because the problem is serious, then the landlord might not sue you for the rent at all. If your landlord does repair the problem, then you will have to move back in for the rest of your lease. However, the court will probably require him to abate your rent and pay your moving expenses. You should get legal advice before.
