What loan rate should I be expecting?

[Joe Marshall]

I have 2 duplexes that I purchased at the same time as my first investment properties. I'm in Wichita, KS. I applied for loans with fixed 30 year mortgages for investment properties. Bought in August 2013.

We have separate 30yr loans for each duplex:

Duplex #1: Purchase Price 87K 20% down, 5.25%

Duplex #2: Purchase Price 80K 20% down, 5.25%

I feel like these rates are somewhat high and I've been trying to shop rates but since they are multifamily, investment properties under 100K I'm having trouble getting rates from any simple processes. What rates have you all seen recently or would you expect to get if I refinanced these properties? I have 700+ credit. 

Note- I am not asking for a loan from anyone here per forum rules. Just a guesstimate on refinance rates I would see.

Thanks for your help!
