Cost of fiber run between neighbouring office buildings

Where I work for a local telecommunications provider, we will not run any fiber smaller than 24 strand, and these days that is a drop into a building. 

When talking about single mode fiber, the cost per foot difference in 2, 8, or even 24 strand is typically a matter of less than $1 per foot. 
Some of the prices I've seen lately on google indicate about $.4/ft for 2-strand, $.5/ft for 6-strand, and $1.8/ft for 24-strand 

It's all about the cost of getting it run by a contractor (which is typical if you have to get conduit installed, or run along telephone/power poles aerial) , unless you're in a position to do it yourself. 

You'd likely have to pay someone to terminate it into a patch panel for you, but it may be cheaper for them to do all strands at once as opposed to having them come back later.

Second what Nick said. Also, get quotes for double, quadruple, and 
more of the number of fibers you think you need today. If it makes 
economic sense to leave strands unterminated (coil neatly in the 
splice tray and have someone term later) by all means do it. Extra 
strands in the cable are almost free compared to the labor to pull it 
in.
