Visit Visa for Mother

[Rida batool]

Hello all
I am planning to apply for my mother visit visa for 2 months.
She has no bank statements but financially she is strong like have a property on her name and also my father and brother are government officer in Lahore .
My father also have other properties.
Have own house.
I have also have 3 siblings who are all studying in Lahore .should I have to apply with these all or she must have bank statements first????
My Uk bank statements are quite good so that wouldn’t be any problem.
Thanks
