The roof and the floors were not huge costs to us the buyer, as the seller filed an insurance claim for water damage just prior to our offer closing.

Compare what you see to the deed etc - there could be a shared driveway or some other easement.Also if the building is occupied you will be dealing with an eviction as well so you will have to factor that into your costs/bid.
