I see a couple of problems with what you are proposing. If you plan on going back to the seller for corrections or consideration for some unacceptable condition with the house. Then, it would be a conflict of interest. If you are inspecting the building to determine if it is economically feasible, the it seems to me that there is no conflict.

However, more importantly, as an inspector, you may be held to a higher standard (lawsuit wise) than a non-inspector, if something is incorrectly repaired or missed during construction. Be really careful.
