Comping a commercial business property (Gas Station)

[Jay H.]

I am wondering - hoping really - that some folks on here might know how to evaluate (comp) a business. I want to purchase a gas station but I think it is over-priced, but I have no education on determining what this place is worth.

There are not "like" properties in the vicinity and I suspect the purchase price is predicated upon income. RS Means does not seem appropriate either.

Can any one direct me..
