Suppose a contract specifies an amount for monthly payment and the tenant pays on time each month for the first two months and then abruptly decides to offer the landlord who lives in anther city the option to collect the owed rent in cash from the rental address if they want to receive it.
Is there any way in which the tenant is now committing a violation of the tenancy?
I suppose even if not it is still wise not to troll one's landlords and keep them happy even on discretionary matters because once the tenancy reaches statutory periodic phase then they can always send a section 21 without any deeper explanation if they're at all unhappy with the tenant for any reason.
Still curious though.
