I was looking for the best landlord/tenant lease agreement

[John Calafato]

Hello

Iam a beginning investor in NJ.Iam about to buy my first duplex.I have tenants for both sides.I was wondering if there was anybody that's been in the business of rentals  for a long time that from mistakes or just learning as they went has a lease agreement template that covers the landlord in every way possible 

Thanks
