Recording seller-financed note payments correctly means splitting interest from principal every time
A common first mistake with seller-financed notes is a spreadsheet with a single column labeled payment received. That treats a note payment as one thing when it is really two arriving in the same deposit. In plain terms: part of every payment is interest, which is income. Part is principal, which is the borrower paying back the balance held against the note. The principal portion is not income, it reduces the asset. Booking the whole deposit as income overstates earnings, sometimes badly. On a smaller note with a few hundred dollars a month of principal, that difference adds up fast if it's counted as revenue. The correct approach: pull the amortization schedule for each note from the servicer, set up each note as its own asset account, and record every deposit as a split, interest to income, principal against the note balance. Once set up as a template, it takes a few minutes per note each month. The part that trips people up most is buying a note at a discount to its face balance. How that discount is treated over the life of the note is a tax question worth answering with a CPA who works with note buyers, since it changes the numbers and the answer depends on the specific situation. Worth keeping in the file: the amortization schedule saved next to the books, and the split entry set up as a recurring template so it isn't skipped. Doing it correctly from month one avoids unwinding months of incorrect entries later, and getting ending balances to match servicer statements to the dollar is the standard to aim for.
