This Residential Lease is between Landlord and Tenant. Tenant shall pay a monthly rent of $1,500, due on the 1st, with a security deposit of $3,000. The term is 12 months and automatically renews unless terminated 30 days prior.
You’ll pay $1,500 on the 1st of every month. Miss the 5th and a $50 late fee kicks in. The $3,000 deposit is refundable at move-out.
