Two units, one detached garage. How to price it?

[Justin R.]

I've got a little dilemma, looking for some advice.

I've got two vacant units (a 4bedroom and a 3bedroom) but only one detached garage.  I've got great applicants for both units, but they both want the garage as an add-on cost to their lease.

I'd love to get the highest price possible, obviously.  How would you go about establishing the cost of the garage?
