7.1 Financing Concepts, Notes, Mortgages, and Deeds of Trust

Key Takeaways

  • The promissory note is the debt (the promise to repay); the mortgage or deed of trust is the security instrument that pledges the property as collateral.
  • A mortgage involves two parties (mortgagor/borrower, mortgagee/lender); a deed of trust involves three parties and adds a trustee who can foreclose nonjudicially.
  • Hypothecation lets the borrower keep possession and use of the property while it secures the loan.
  • Key clauses—acceleration, alienation (due-on-sale), defeasance, prepayment, and subordination—change borrower and lender rights and are heavily tested.
  • Lien theory, title theory, and intermediary theory states differ on who holds title during the loan term.

The two-document structure

Nearly every financed sale uses two instruments. New licensees lose points by collapsing them into one.

  • Promissory note — the borrower's written promise to repay. It is the actual debt. It states the principal, interest rate, payment amount, term, and default terms. It is a negotiable instrument the lender can sell.
  • Security instrument — pledges the property as collateral for the note. It is either a mortgage or a deed of trust. It is recorded; the note usually is not.

Think of it this way: the note says "I owe you the money." The security instrument says "and if I don't pay, you can take the house."

Hypothecation

Hypothecation is pledging property as security for a loan while keeping possession and use of it. The borrower lives in the home throughout the loan; the lender holds only a lien or contingent title interest, not the keys. This is why a financed buyer can occupy immediately.

Mortgage vs. deed of trust

FeatureMortgageDeed of Trust
Parties2: mortgagor (borrower), mortgagee (lender)3: trustor (borrower), beneficiary (lender), trustee (neutral third party)
Who holds the security interestLenderTrustee holds bare/naked legal title for the lender
Typical foreclosureJudicial (court)Nonjudicial via power-of-sale clause (faster)
Reconveyance on payoffSatisfaction/release recordedTrustee issues a deed of reconveyance

Memory aid: mortg-AGOR = borrower (the one giving the mortgage), mortg-AGEE = lender (the one receiving it). The borrower gives the pledge to the lender.

Title, lien, and intermediary theory

Who holds title during the loan depends on the state.

  • Lien theory — the borrower holds title; the lender holds only a lien. Foreclosure is usually judicial. The borrower keeps title and possession.
  • Title theory — the lender (or trustee) holds legal title until the debt is paid; the borrower holds equitable title and possession.
  • Intermediary theory — a hybrid: borrower holds title, but title shifts to the lender on default.

On the exam, if a question says "the lender holds a lien only," you are in a lien-theory frame; "the trustee holds naked legal title" signals title/deed-of-trust frame.

Key clauses (high-frequency tested)

ClauseWhat it doesWho it favors
AccelerationOn default, makes the entire balance due at onceLender
Alienation (due-on-sale)Loan must be paid in full if the property is sold/transferred; blocks assumptionLender
DefeasanceRequires lender to release the lien when the debt is paidBorrower
PrepaymentAllows early payoff; a prepayment penalty charges a fee for itVaries
SubordinationA lender agrees its lien takes lower priorityThe other lienholder
Release (partial)Frees specific parcels from a blanket lien as they sellBorrower/developer

Trap: Acceleration must usually be triggered before foreclosure—it is what allows the lender to demand the whole balance, not just the missed payment. Trap: An alienation clause is what prevents a new buyer from simply assuming the existing loan; without it, loans may be assumable. Do not confuse acceleration (about default) with alienation (about sale).

Foreclosure and the borrower's safety valves

When a borrower defaults and the lender accelerates, the property may be sold to satisfy the debt. The exam separates the two pathways and the borrower's rights.

ConceptMeaning
Judicial foreclosureCourt-supervised sale; standard in lien-theory/mortgage states
Nonjudicial foreclosurePower-of-sale by the trustee; faster, common with deeds of trust
Equitable right of redemptionBorrower pays the full debt before the sale to keep the property
Statutory right of redemptionIn some states, borrower redeems after the sale within a set period
Deficiency judgmentLender sues for the shortfall when the sale brings less than the debt
Deed in lieu of foreclosureBorrower voluntarily deeds the property to the lender to avoid foreclosure

Worked example: A home with a $260,000 loan balance is foreclosed and sells at auction for $230,000. The lender recovers $230,000 and, where allowed, may pursue a deficiency judgment for the remaining $30,000. A short sale would have addressed the same gap before foreclosure, with lender consent to accept less than the full payoff.

Junior vs. senior liens and purchase-money loans

A senior (first) mortgage is recorded first and is paid first from sale proceeds; a junior (second) mortgage or home-equity line is subordinate. A purchase-money mortgage is financing used to buy the property (sometimes seller-financing), and a package, blanket, or construction loan covers, respectively, personal property plus realty, multiple parcels (with partial-release clauses), or staged building draws.

Trap: A subordination clause can flip the usual order — an existing lender voluntarily agrees that a later loan (often a construction loan) will hold higher priority. Without such an agreement, recording order controls. Defeasance, by contrast, has nothing to do with priority; it simply forces the lender to release the lien once the note is fully paid, clearing the title.
