The Bolton News understands a decision on the winning bid will be made by this time next week, meaning a new owner is still on track to take charge by the start of pre-season training.
The number of completed bids has been a pleasant surprise to the Rubin and Partners administration team, who were appointed on May 13.
They will now analyse each bid and assess which best meets the needs of the secured creditors, football creditors and unsecured creditors at the club.
Each bidder had to produce sufficient proof of funds and pay a £25,000 fee to see the data room containing sensitive financial information, which is only refundable if the offer is successful. Bidders were also asked to begin the process of getting ratified by the EFL.
