that 6252 is almost totally incorrect
as best as i can figure from what you provided
line 5 the 210K sales price
line 6 nothing - the installment proceeds to be received in the current and future years is not report ed on this line
line 8 27K the cost of the land
lin11 21K sales expenses
line 16 gross profit should be 162K (210K-27K-21K)
line 19 162/210
line 21 50K (the down payment + 319 principal received on the 2024 payments.
it also seems like you'll have a huge balloon payment in year 5 since 959 per month will not fully amortize the loan of 160K in 5 years.
