FILING CHAPTER 7 IN CALIFORNIA

First, I own a timeshare free and clear, do I need to list it in one of the schedules, if so, where? Second, is a HELOC (Home Equity Line of Credit) a secured or unsecured claim; re real property, is the description of property, i.e., single-family dwelling, is the location the address, what is meant by 'nature of debtor's interest and unsecured portion of claim or lien? Third,is a 'homestead exemption' and a'homeowners exemption' one in the same. My property tax bill shows a $7,000 'homeowners exemption'. Again, I live in California. Thanks for your advice. DGranny
