Based on the amount he bought the place for and the annual depreciation, the capital gain would be $363,538.
First find the depreciation on the property so far.
= (Sum of lot and construction price) / 39 years x 15 years
= (43,000 + 520,000) / 39 x 15
= $216,538
= Selling price - (Property purchase and construction value - Depreciation)
= 710,000 - (43,000 + 520,000 - 216,538)
= $363,538
In conclusion, he made a capital gain of $363,538.
