Question: Auction Purchase with Quitclaim Deed – Title Concerns

Does anyone have experience purchasing a mixed-use property on an auction site sold "as is" with a quitclaim deed? I'm wondering if outstanding mortgages, taxes, or violations carry over.

The auction states that the title is free and clear of liens, but the contract only mentions a quitclaim deed without explicitly confirming a clear title. This is my first auction purchase, so any insights or advice from those familiar with this process would be appreciated.
