Loss deduction: Can a loss from the sale of inherited property be deducted for federal taxes?

Yes, if the inherited property loss value from the date you inherited it AND you never used the property as your personal residence.

It depends upon the type of the property. If from the day you inherited the property, you kept it to sell it, then you can deduct the loss.
It you planned to use it as your residence or used it as residence, then you can not deduct the loss.
