Hi,
I am MBB banker,

Yes, top up loan is 10years tenure if your DSR is more then 70% with nett income more then RM3500.00.
However, In MBB we do offer longer tenure on top up loan if applicant DSR lesser then 70%, top up tenure can up to 35years/70years old(professional) and 30years/65years old which ever come earlier.

If applicant top up on existing MBB housing loan, up to original loan amount, top up tenure can be up to 35years.
