Anyone familiar with California HOA foreclosures?

[Shireen Y.]

If a property owned free and clear is sold at an HOA foreclosure auction, which law (SB1079 or Cal. Civ. Code 5715) applies?

For SB1079, a prospective owner-occupant can bid on the property post-sale and win the auction within a 45-day period. For Cal. Civ. Code 5715, the homeowner has 90 days post-sale to redeem the property. Which law applies in the case where an HOA organization is foreclosing the property? No one seems to have the answer to this. The trustee says they "cannot provide legal advice".
