Home office?

Ok so the house we are going to live in is unique in that it has 2 offices attached to it. The offices face Highway and the house is behind the offices.
The house/office building is huge and modern styled. The house offers 3 bedrooms and vast living areas - plus 2 "bonus" rooms that could be used as a home office (we can put in a separate entry).
Alternatively, I could take one or both of the offices giving me a bit better exposure and larger signage.
I wonder how important this is? The cost difference is about 8K per year...and I'm wondering if the highway front would bring in that much extra business.
For now, the tentative plan is to home office for the first few months and see if I can turn a profit--then think about expanding.
btw: we know the place needs work! But we will have almost a year to fix it up. Anyone wanting to help is welcome :)
