Investors & landlords

I went thru and completed the sale of the rental property and then went back to the asset summary screen and indicated that I had stopped using the asset. It then walked me thru inputting the sales info but now my sale has doubled? Where did I go wrong? 

I had sales price of $40000.00

Cost was $22617 with $5400 of this allocated to land

Prior depreciation on structure was $17034

Cost of Improvements was $17306

Prior depreciation on Improvements was $11835

Sales expense was $2400
