Consolidating loans

Hi, I would appreciate some advice. At present I have 5 loans with 3 banks.
I have 3 investment properties

Bank A
Loan 1: home (PPOR)
Loan 2: Line of credit for investment property expenses
Loan 3: Investment loan

Bank B
Loan 4: Investment loan

Bank C
Loan 5: Investment loan

I was thinking about consolidating loans to one bank. Any pro?s and con?s.

Thanks
