Arm loan - Fixed Rate Loan

[Ewka Kawecki]

I have a property under contract (4 units) I'm shopping around for a mortgage and need some advice. 

Which option will you choose, which one will be cheaper from a long-term perspective? Both options are Credit Unions - no points, no origination fee

1. Fixed rates - 6.125

2. Arm Loan - 5.250 (after five years the rates can go up 1.25%  ( I will need to refinance before year 5)
