Is 5.50% a good investor interest rate?

[Rhondalette W.]

I am purchasing my 2nd rental property "buy and hold" with conventional financing 20% down. I have very good credit score probably around 800 (i think).  Do you think 5.50% is a good interest rate or should I shop around for a lower rate? Can investors get a better rate?

Thank you in advance for your advice.
