It would truly depend on a number of factors, but the most important is this.... Is this house worth the pontential investment that it could cost to cure a mold infested house. What is the severity of the mold infestation? ..........................If this truly is the house that you want, and has the potential of being a great home, I would make an offer on the home contingent on a Mold inspection to start. I hope this answer helps.
