This is totally unhelpful for me. How do I do this? Which one first? How do I zero out the mortgage account?
As written, the suggested entry is a split entry that starts in the checking Account, with the split items zeroing out the balance of the mortgage loan and zeroing out the basis of the house. The remaining amount would be the gain or loss on the sale.
If you don't want to do that and only want to zero out the two Accounts then simply make and entry in each Account for the current balance with the offset being the same Account in which you are making the entry, surrounded by square brackets, e.g., [Name of Loan Account] and [Name of House Account].
