Upon the recommendation of a physician, Roberto has a therapeutic pool installed in his personal residence. He suffers from severe muscular degeneration disease. If Roberto does not use the pool on a regular basis, his muscles will deteriorate to the point that he will be unable to walk. In connection with this pool, Roberto incurs and pays the following amounts during the current year.

Therapeutic pool and cost of installation	$11,000
Increase in utility bills due to the pool	$400
Cost of certified appraisal	$500

The pool has an estimated useful life of 5 years. The appraisal was to determine the value of Roberto's residence with and without the pool. The appraisal states that the pool increased the value of Roberto's residence by $4,000. Disregarding percentage limitations, how much of the above expenditures qualify for the medical expense deduction in the current year?
