Investors & landlords

This does not help me.  I know how to enter the sales information for the rental.  However, if I add an asset (heating system) there are a series of questions that follow in the screens.  It asks me about the sales price of the asset; date it was sold,  The sales price and the expenses.  I don't know what to put in.  Is the sales price of the asset (the heating system) the same price I paid for it?  It also asks me to allocate my expenses.  Not sure what I do here.
