The council refused to give specifics in response to a query about how the purchase price was calculated.
It said the final price was reached through confidential discussions at mediation with the homeowners rather than being calculated.
The council did not believe the confidentiality of the mediation process outweighed public interest in the question of how settlement numbers were reached.
Homeowners said publicly before the mediation that they wanted a market rate as if there were no defects.
Tauranga Mayor Greg Brownless said yesterday that several houses may be able to be fixed, and he was keen for the council to try to bring them up to high quality before attempting to sell them.
"We've got to try to get as much as possible from that. It's a hard job."
Brownless said he did not believe the stigma of the Bella Vista debacle would significantly affect the sales.
"There's a demand for properties ... once done properly, there will be no issue. There might be some leftover worry but not so much to be a problem, I think.
"I'm not downplaying the situation. It's bad. But ... we are well on the road to getting it right.
He said the council was trying to protect the ratepayers' interests and recover as much of the money it had spent as possible.
As of September 18, the council had also racked up costs of $2.8 million dealing with the Bella Vista fallout, including building, geotechnical and structural assessments, solution assessment, legal advice, communications, security, investigations and homeowner support.
Multiple sources have credited the council's new chief executive, Marty Grenfell, for bringing the negotiations, which started after the council voted in principle to buy the homes in June, to an end.
The council had an $11.5m provision in its annual report for the Bella Vista buyout.
