there is no eviction filed. I keep asking for repairs to be done. since i started asking for repairs he is threatening eviction but has not done anything more than threaten. (falsely) saying he could have me out in 2 wks if he chose to for any reason he chose. So if I send the letter (with seven days before rent due) do I start depositting on the 1st? And everything i read said i would have to have partial payment available so do i deposit entire rent or a percentage?

I am not sure what you are referencing about the letter being sent 7 days before the rent. Is this in your lease? I am unfamiliar with any statutory procedure which allows this. I am familiar with the procedure once eviction starts and you have to deposit 100% of the funds into the Court Registry. I am familiar with withholding to cover for expenses that were incurred in remedying the landlord's obligations. Running water is one, but having a dryer is not. I suggest you speak with an attorney locally to clarify what youare doing and how you go about doing it.
