Sorry. For your personal home (not a rental or business property) you sold the real estate (land plus anything permanently attached) for the price listed. You likely signed a document transferring the contents for a nominal fee (like $1). You can't deduct a loss because you sold personal items for less than their value, and it's not an adjustment to the home sale price either.
Allowable adjustments to cost basis are listed on page 8 here.

If this was a rental property, we have to get into discussion about depreciation and adjusted cost basis, and whether the items were listed as expenses or were on your asset list.
