A short sale may be complicated if the loan has been sold to the secondary market because then the lender will have to get permission from Fannie Mae or Freddie Mac, the two major secondary-market players.

If the loan was a low-down-payment mortgage with private mortgage insurance, then the lender also must involve the mortgage insurance company that insured the low-down loan.

A borrower can cure the default by paying the overdue amount and the pending payment after the notice of default is recorded, usually no later than a few days before the property's sale.

Some sales allow the successful bidder to take possession immediately. If the former owner refuses to vacate the premises, the court can issue an unlawful detainer that allows the sheriff to come out and evict them.
