No, the price paid at auction will NOT settle other persons' or parties' claims: the foreclosing lender cannot compromise, dismiss, eliminate, settle, etc. other parties' claims without their consent, and they will not consent unless they are paid. So unless the bank is taking their money and giving some or all away to the other potential claimants and getting signed settlements from them--which you can assume is not happening--other claims may and likely do exist.They have to file their claims before their respective statutues of limitation run out, but not any time before then--other parties can wait to file. Therefore, there is no way, until years have gone by, to know for sure whether they will or will not file.Based on what you write, you could be exposing yourself to considerable other claims if you buy this property.
