It is now June. You moved in January 1. The plumbing was bad when you moved in. You told your landlord in writing about the bad plumbing right away. The roof has leaked since March, and you told the landlord in writing as soon as it started to leak.
If you have not paid June rent, you can start a Rent Escrow case by putting the unpaid June rent into court along with the attached Rent Escrow affidavit and a copy of your letters from January and March. You can ask the judge to make the landlord fix the problems. You can also ask for some money off the rent for January and February because of the bad plumbing and a larger amount off for March, April, May and June, because of the second problem, the leaky roof.
So, out of the money you paid into court, some of it should go back to you because of the repair problems that were not fixed. Also, ask the judge to lower your future rent until the landlord makes all of the repairs.
It is important to note that the judge has a lot of power to decide how much of a rent reduction you should get. Different judges give different values to repair issues, so the amount of rent reduction can be very different depending on who decides your case or where you live.
Remember: The main point of a rent escrow case is to get repairs made, not to get rent back. This is why it is important for you to show how each problem affected you and made your life worse in the rental home. Proving how each problem made your life worse can help convince a judge to give you a rent reduction along with ordering repairs.
