That depends on what he makes on it. As long as it was his primary residence for at least 2 years, he can make up to $250,000 without getting taxed. It's rather late in the day, but I believe that if he bought for<$352,000 and makes 71% he will be under that threshhold. Presuming that 71% is after the realtor and attorneys take their portion.Only problem i see, if he doesn't reinvest profit within 6 months….i believe thate the term… hes going to be hit with some huge taxes.
