In the State of Maryland; if a landlord rents an apartment to a tenant knowing that the tenant is on SSI (social security income) and also knowing that the tenant doesn't get paid until the first of the month, because of this issue, is it allowed for the landlord to penalize the tenant if the tenants SSI check is not received in the landlords hands on the first of the month, but in addition to it is still paid on the first of the month and mailed out by money order on the 1st of the month. ; The rent money order does not come to the landlord until a few days later but is paid on the first. The landlord wants the money on the first but the landlord lives out of town so it takes the post office several days to deliver. The rule is the money is to be paid on the first, and the money order says it is; but is not received in the landlords hands because the landlord lives out of town. Should the tenant be charged 5% late fee?
