*DEPRECATION can only be taken on the improvements (80%) portion of the purchase price.
in this example 80% x 750,000= 600,000 (improvement portion of the original basis).
600,000 x .02 (2%)= 12,000 x 5 years=$60,000 (accused deprecation).
subtract the accused depceaion from the original cost bases $750,000 (original cost basis) - $60,000 (accused deprecation)= 690,000 (deprecation cost basis) finally, add $50,000 for the new swimming pool improvement + 690,000 (depricaiotn cost basis) = 740,000 (adjusted cost basis).
