Real estate professionals who work with seller financing need a working command of 15 core terms to protect clients and close deals cleanly. From the promissory note and deed of trust to balloon payments, junior liens, and due-on-sale clauses, these terms define how private mortgage notes are structured, serviced, and enforced.

Seller Carryback & Private Note Terminology

Seller Carryback (Seller Financing)

Seller carryback — also called seller financing — happens when the property seller acts as the lender, extending a loan to the buyer for part or all of the purchase price. The buyer makes payments directly to the seller instead of a bank. This arrangement creates a private promissory note that requires professional loan servicing to collect payments, maintain records, and keep all parties in compliance with the note’s terms. For real estate professionals, understanding the seller carryback structure is not optional — it is the foundation of the transaction.

Promissory Note

A promissory note is a legally binding written promise by the borrower to repay a specific sum to the lender under defined terms. It sets out the principal amount, interest rate, payment schedule, and maturity date — making it the core financial instrument in any private mortgage transaction. For private note holders, the note is the asset itself: it represents the right to receive future payments. Accurate, complete documentation — including the original signed note — underpins all payment processing, legal enforcement, and any future sale or transfer.

Deed of Trust / Mortgage

A deed of trust or mortgage is the legal instrument that secures the promissory note by pledging the property as collateral for the loan. State law determines the structure: a deed of trust involves a third-party trustee, while a mortgage is a direct two-party agreement. Both instruments create a lien on the property and give the lender the right to foreclose if the borrower defaults. Proper recordation establishes lien priority and is a non-negotiable requirement for compliant private mortgage servicing.

Loan Servicing

Loan servicing is the comprehensive management of a private mortgage note from origination through final payoff. It covers collecting and applying payments, maintaining accurate payment histories, calculating interest, issuing year-end tax statements such as Form 1098, and managing escrow accounts for taxes and insurance where applicable. Professional loan servicing keeps the note in compliance with state and federal regulations and protects both borrower and note holder. For a guide to tax form requirements, see 1098 vs. 1099-INT: The Private Mortgage Tax Reporting Guide.

Amortization Schedule

An amortization schedule is a table that maps each loan payment to its split between principal reduction and interest cost over the life of the note. In the early years of a fixed amortizing note, a larger share of each payment covers interest; as the loan matures, more of each payment reduces the outstanding principal balance. For example, on a $200,000 note at 8% interest over 20 years, the fixed monthly payment is $1,672.87 — and the amortization schedule shows exactly how that amount splits between interest and principal at every step. Private note holders rely on accurate schedules to verify balances, generate payoff statements, and confirm correct payment application.

Expert Take

Amortization schedules are where servicing errors compound fastest. A single misapplied payment throws off every future balance calculation, payoff figure, and tax statement. Private note holders who self-service without automated amortization tracking regularly discover discrepancies only when a payoff is requested — and by then, correcting the record requires reconstructing years of payment history from scratch.

Balloon Payment

A balloon payment is a large lump-sum payment due at the end of a loan term, preceded by a series of smaller payments that are interest-only or partially amortized. Balloon structures are common in private mortgage notes because they keep monthly payment obligations manageable during the initial term, with the expectation that the borrower will refinance or sell the property before the balloon comes due. Professional servicers track balloon maturity dates and issue advance notice to both borrower and lender — failure to provide that notice is one of the most preventable default triggers in private note portfolios.

Junior Lien (Second Mortgage)

A junior lien is a claim against a property that is subordinate to another lien — ranked below the senior or first lien in priority. In a foreclosure, the senior lien holder is paid in full before any proceeds reach the junior lien holder. Seller carrybacks take the form of junior liens when an existing first mortgage remains in place on the property. Real estate professionals and investors who hold junior liens carry elevated default risk because recovery depends on whether property value exceeds the senior balance after a forced sale.

Wraparound Mortgage (All-Inclusive Trust Deed — AITD)

A wraparound mortgage — called an All-Inclusive Trust Deed (AITD) in some states — is a form of seller financing where the seller keeps an existing mortgage in place and extends a new, larger loan to the buyer. The buyer makes one payment to the seller, who forwards the portion needed to service the underlying senior mortgage. This structure requires the servicer to track both the wraparound note and confirm the underlying senior lien is paid on schedule — meticulous record-keeping and close coordination are non-negotiable. For a detailed breakdown of wraparound servicing requirements, see 7 Critical Factors for Profitable and Compliant Wrap Mortgage Servicing.

Discounting a Note

Discounting a note refers to selling a private promissory note for less than its remaining principal balance — its face value — in exchange for immediate cash. Note sellers accept a discount to access liquidity quickly, exit the servicing obligation, or shed an underperforming asset. The spread between face value and sale price is the discount; it determines the investor’s actual yield. Sellers considering a note sale need to understand how the discount is calculated and what documentation a clean assignment requires. See A Comprehensive Guide to Selling Business Notes with Real Estate Collateral.

Yield (on a Note)

Yield on a note is the effective annual rate of return an investor earns from purchasing a private mortgage note. It differs from the stated interest rate because it accounts for the actual purchase price — whether at a discount or premium — along with the payment schedule and remaining term. Calculating yield is how investors determine whether a note is worth acquiring at a given price. Real estate professionals who understand yield give clients an accurate picture of what their note is worth in today’s secondary market — the right foundation for any note sale conversation.

Default

Default occurs when a borrower fails to meet the terms of the promissory note and deed of trust — most commonly by missing scheduled payments. Other default triggers include failure to pay property taxes or maintain required insurance coverage on the collateral. Once a default is declared, the note holder has the right to pursue legal remedies up to and including foreclosure. Professional loan servicing protects note holders by issuing required notices, documenting every communication, and working with the borrower to cure the default where viable. See 7 Warning Signs Your Note Is Going Non-Performing to identify risk before a formal default is declared.

Foreclosure

Foreclosure is the legal process by which a lender repossesses and sells a property to satisfy a debt after a borrower has defaulted. States follow one of two processes: judicial foreclosure, which requires court involvement, or non-judicial foreclosure, exercised through a deed of trust’s power-of-sale clause. Foreclosure is the last resort — it is time-consuming, expensive, and legally complex. Private note holders need proper legal documentation in place from origination, managed through professional servicing, to navigate the process without losing position or triggering additional liability. See 10 Real Examples of Default Servicing and Foreclosure Administration for Private Lenders.

Assignment of Note

An assignment of note is a legal document that formally transfers ownership rights and interest in a promissory note — along with its associated deed of trust or mortgage — from the original lender (assignor) to a new lender (assignee). Assignment is required any time a private note is sold or transferred between parties. Without a properly executed and recorded assignment, the new note holder lacks legal standing to receive payments or enforce the loan terms. A clear chain of title in private mortgage servicing depends entirely on documented, recorded assignments at every transfer. See 7 Things That Happen to Your Note When You Transfer Loan Servicing.

Escrow (for Private Notes)

In private note servicing, escrow is the process where a third-party servicer collects and holds funds from the borrower for property taxes and homeowner’s insurance premiums. Escrow protects the property’s value and the lender’s collateral by ensuring those obligations are paid on time, reducing the risk of tax liens and lapsed coverage eroding the note holder’s security position. Private note holders who require escrow on their notes shift the administrative burden of tax and insurance tracking to the servicer — a significant compliance and risk-management advantage. See 5 Things to Know About Escrow Account Setup for Private Mortgage Notes and 5 Things to Know About the Escrow Disbursement Process.

Due-on-Sale Clause

A due-on-sale clause is a provision in a mortgage or deed of trust that makes the full loan balance immediately due and payable if the property is sold or transferred without the lender’s prior consent. Institutional lenders include this clause to prevent unauthorized loan assumptions. Real estate professionals structuring seller carrybacks must identify whether an existing senior loan contains a due-on-sale clause before proceeding — triggering it without a plan in place creates an immediate default scenario for the seller on the underlying mortgage. See 7 Seller Financing Pitfalls Private Lenders Must Avoid for how to navigate due-on-sale risk in creative financing structures.
