 Back in the days when I did landlord-tenant law, that was always a favorite tool for my tenants to use because the tenant can say in a seven-day notice, hey, here's the problem. The air conditioner doesn't work or the toilet's broken or the dishwasher's broken, and I'm giving you seven days to fix it. And if you don't, I would always tell the tenant to actually put in the amount of rent that they were going to withhold until that problem does get fixed.
