You need to find out what your father-in-law paid for the house. In Ohio, that is on file at the county auditor's office. Any gain over the price paid is a taxable capital gain. If you have a loss, it's not deductible because it was personal not business use. When you have taxable capital gain, you're required to file Form 1040 with Schedule D attached.
