I am about to sign a lease agreement with a Cell Tower Operator ( I own the property the Cell Tower is on) who will sublease the tower to T Mobile.They told me that the rent will commence when they start getting rent from their tenant ( T Mobile ) in about 3 months.Is it standard procedure? Shouldn't the rent start at the signing of the lease agreement?Also,is there such a thing as a silent agreement in a lease? I was told that they can sublease my property if the lease doesn't state that they can't. I was told that is is called "a silent agreement"???Is there such a thing???
