Lots of investment loans

[Chase Gochnauer]

Hello all. I have around twenty to twenty five mortgages on various investment properties. They are all currently 4.25-4.5% locked for five years with a 20 year amorts. These are all through a local bank. I have three new ones I am looking to finance and am looking for a strategy to lock in the rates for longer terms and get 30 year amorts. I plan on holding for the long term. Does anyone have any recommendations on a good loan structure for this? Are my current rates about as low as I can get currently? Thanks!
