I'm going to show you a way to record the sale of a financed asset uh in QuickBook so you can record the gain rate record the cash you get. What is the journal entry for sale of a fixed asset, including payoff of a mortgage loan and net gain on the transaction?Should I use a Journal entry again and get rid of the asset and diminish my Loan to 0 and only then dispose the Fixed asset? What would my journal entry look like? You debit the assets bought at market value, which is now book value. You credit the liability with the remaining balance of the loan. When we're talking about the gain or loss of the sale of an asset we need to be looking at net book value at the time of the sale. In the journal entry, credit your asset accounts for the property, using the original purchase prices. FORM NYCRPT Real Property Transfer. General information.
