Cash Cow's

I want to get into storage unit business i have found a couple of smaller established set ups and have considered starting from the ground up. any idea the way to go about financing such a plan? one of the established places has a cap rate of 8.5% which isnt too bad. im really new to this and planning on going thru the Meyers program. but im looking for any advice?

I would rather see a 12% cap minimum. 8% is too low and definitely not in the category of a Cash Cow. I buy rental property on a regular basis in the 15-18% cap rate.
