Reasonable interest rate for conventional loan on rental?

[Evan Shuey]

Hello there, 

I am in the process of buying my first rental through a turnkey company in KC (Bridge), and I am being told that my interest rate for my loan will be 5.67%. I believe this is a bit high since I have near perfect credit and a really great debt to income ratio. But I also know that investment property mortgages (even the ones through FMFM) are going to be a bit higher. This will be only the second house I have owned. Does anyone have a ball park of rates these days for this type of situation? In Colorado where I live I have gotten rates quoted at 4.5-4.75%. That's why I am a bit confused. 

Thanks all for the help!
