Are $1M+ commercial loan terms better?

[Amy A.]

I am looking to expand my portfolio into bigger multifamily properties out of my area. Right now all of my loans for 5+ units are with a local bank. They are around 4.5% interest, 5 year fixed with 25 year amortization. Pretty low closing costs. 25% minimum LTV. My largest loan is around $450k.

I've heard somewhere that commercial mortgages of over $1M have better rates that are fixed long term.  Is this true or am I looking for a unicorn?  Thank you.
