Linda had a swimming pool constructed at her house in 2019. Her physician advised and prescribed to her that the pool would slow the effects of her degenerative disease. Prior to the construction of the pool, the fair market value of her house was $172,000. After the construction of the pool, the appraised fair market value of the house was $181,000. The cost of the pool was $13,000. What is the amount of expense related to the pool that Linda can include in her total medical expenses (before applying the AGI limitation)?
