Answer:
A) Bruce's basis in the land at the time of the sale = $100,000 (same as his father's)
B) When computing his realized gain, what amount does Bruce use as the selling price and as the contract price?
Selling price= $360,000.
Contract price = $360,000 (selling price) - $120,000 (assumed mortgage) = $240,000.
C) Bruce's total realized gain on the sale = $360,000 - $10,000(selling costs) - $230,000(land + improvements) = $120,000
But his recognized gain in the year of the sale is = ($120,000 / $240,000) x $90,000 = $45,000
