Investors & landlords

You will want to enter the $275,000 as the sales proceeds, then enter the half of the fair market value and sales expenses/roof repair.  

If you or your sister did not use the home for personal use, you will be able to claim the capital loss on your tax return.  (It may be subject to the long term capital loss limitation, which does have a carryforward).  If you sell or dispose of inherited property that is a capital asset, the gain or loss is considered long term, regardless of how long you held the property.
