Answer:
$671,300
Step-by-step explanation:
The calculation of adjusted basis in the building is shown below:-
Adjusted basis = Original cost of the property + Cost of capital improvements - Depreciation claimed
= $750,000 + $50,000 - $128,700
= $800,000 - $128,700
= $671,300
Therefore for computing the adjusted basis we simply add original cost of the property with cost of capital improvements and deduct depreciation claimed.
