This is a stressful situation for everyone.

You need to have written policy in how you deal with tenants and apply that policy across the board.If you allow pets under a certain weight, they have to be allowed across the board.If you have a policy that all tenants must make 3 times the rent, then all tenants must meet that.And if you have a policy about waiving late fees, or reducing rent, or waiving one month of rent, whatever it is, you really need to apply to all.When landlords get into case by case basis with a different rule or decision for every tenant, that's when you set yourself up for a fair housing violation.

The n is a multiplier which is the number of years you have occupied the property.If this is your forth year as a tenant, then the number works out to be $50*4 = $200.If this is your first year as a tenant, then the number is just $50*1 = $50.This is then the amount you can deduct from your rent for a period of say 60 days or longer (TBD) IF you the reduced rent on time.
