What is the interest rate for income property over five units in California?

I want to buy an apartment with 6 units but I am wondering what I will be looking at as far as the interest rate. I am looking at both fixed and adjustable. I need to keep the rate as low as possible. I have great credit, good income, and also own four single family properties that less than half the value is owed. I want to put a down payment of 10-15%. Any and all help and advice would be greatly appreciated! Thank you|||Rates for 5+ units are hovering around 6.25 percent for loans over 500K. Expect rates around 6.5 to 6.75 for loans under 500k
