What you need to check most carefully are the contents of the property description, such as "Rights of others that the buyer will bear," "Special notes on the occupancy status of the property," and "Other matters that may be helpful for the buyer," which are likely to cause problems with the current owner or a third party tenant after the auction, and the contents of the "Property Description," which describes a large amount of arrears of management fees to the condominium association.
In the "Property Inventory" at the beginning of the public documents of the auctioned property, it may be overlooked that there is a public notice about the fact that ownership of the land cannot be acquired or that only one-half interest can be acquired.
