[Jignesh Savaliya]

Tenet's current 1 year lease will complete in Aug 2021, tenant want to stay for 4 more years with reason of child school. so far tenet behavior is good in terms of Paying rent on time, Keeping property clean, Sometimes fixing things by them self and not disturbing other tenet.

Should I sign 4 years lease with rent increase ?
or sign 24 months lease with rent increase ?
or just stick to the yearly lease formate ?

Note: Property location is in North Austin TX area.
