Seller carryback next to a third-party commercial mortgage

On an investor-owned commercial purchase, the seller sometimes offers to carry a note for part of the price. Wikipedia's seller-financing article, opened October 28, 2026, defines seller financing as a loan provided by the seller of a property or business to the purchaser. It says there are no universal requirements, and that a legally binding purchase agreement should be drawn with an attorney and signed by both parties. It also spends many paragraphs on residential buyers with weak consumer credit. That residential path, including any discussion of who should or should not use it to buy a home, is not this note. The collateral here is investor-owned commercial real estate. A house the buyer will live in is out. One-to-four-unit residential property is out. This note is general information. It is not tax advice, legal advice, or an appraisal. A CPA, an attorney, or the other professional named in the note decides how the rule applies to a given property.

The article mentions that a seller might negotiate price or terms, including interest. This page does not quote a rate and does not suggest one. Price and coupon belong in the note your lawyer drafts and in the senior lender's term sheet, not in a blog example.

How a senior lender usually looks at a seller second

A bank, a life company, or a conduit lender financing the first mortgage may treat a seller note as extra debt that competes for cash flow. Some will allow it only if the seller subordinates, stands still on payments if the senior loan is in trouble, and signs an intercreditor agreement. Some will not allow it at all. Those are credit conditions. They are not sentences in the Wikipedia article that was opened, so they are not attributed to it. Ask the senior lender in writing, and have counsel read the subordination. A seller note that balloons before the senior loan matures is a refinance risk of its own. Balloon timing, in an Arizona commercial context, is discussed on commercial balloons. Debt that sits behind a first mortgage and is not a seller note is compared on mezzanine and preferred equity.

The purchase itself, once you know a third-party loan is the path, is acquisition. Who arranges versus who lends is broker versus lender. Capital Market Funds arranges financing with third-party lenders. It does not take the seller's note onto its own books, and it is not the seller.

Tax and title are not decided here

Whether the seller's note is an installment sale for tax purposes is a CPA question. Whether the buyer receives title, and what lien is recorded in which order, is a lawyer and title question. Wikipedia notes that in some residential seller-financed deals the buyer may not receive title the way a regular mortgage buyer does. Do not import that sentence into a commercial deed without counsel. Commercial practice is whatever the documents and Arizona law say for that parcel.
