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

Key Takeaways

  • Two instruments secure a loan: the promissory note is the borrower's personal promise to repay; the mortgage or deed of trust pledges the property as collateral.
  • A mortgage is a two-party instrument (mortgagor borrower, mortgagee lender); a deed of trust is three-party (trustor, beneficiary, neutral trustee who holds title).
  • Lien theory states leave title with the borrower (lender holds a lien); title theory states place title with the lender or trustee until payoff.
  • Key clauses: acceleration triggers on default, alienation (due-on-sale) on transfer, defeasance releases the lien at payoff, subordination reorders lien priority.
  • Hypothecation pledges property as security without giving up possession; the borrower keeps using the home while the lien stays recorded.

Two Documents, Two Jobs

A financed purchase creates two separate legal documents, and confusing them is the single most common error on this part of the exam. The promissory note is the evidence of the debt. It is the borrower's written, personal promise to repay a stated amount at a stated rate over a stated term. It is a negotiable instrument: the lender can sell or assign it on the secondary market.

The security instrument, a mortgage or a deed of trust, pledges the real property as collateral. If the note is not paid, the security instrument is what lets the lender force a sale. The note creates the obligation; the security instrument attaches that obligation to the land.

Think of it this way: the note is the promise, the mortgage is the leash.

Hypothecation and Pledging

Real estate loans rely on hypothecation: the borrower pledges the property as security for the debt while keeping possession and use of it. Nobody moves out; the lien simply sits on title until the debt is satisfied. This is why a homeowner can live in, rent, or improve a mortgaged home even though the lender has a recorded interest.

Contrast this with a pawn arrangement, where you surrender the item itself. Hypothecation surrenders only a contingent claim, enforceable through foreclosure if the note defaults.

Mortgage vs. Deed of Trust

Both instruments secure the note, but they involve different parties and different default mechanics.

Table: Mortgage vs. Deed of Trust

Third partyNoneTrustee (holds title)
Typical foreclosureJudicial (court)Non-judicial (power of sale)

A memory hook: the party giving the instrument always carries the -or suffix (mortgagor, trustor), and the party receiving security carries -ee (mortgagee) or is the beneficiary. The trustee is a neutral third party, often a title company, who holds bare legal title and can sell the property without going to court if a power-of-sale clause exists.

Lien Theory vs. Title Theory

States split on who technically holds title during the loan term, and the rule drives the foreclosure process.

  • Lien theory (majority rule): The borrower holds title; the lender holds only a lien. Foreclosure is typically judicial.
  • Title theory: The lender or a trustee holds legal title until the debt is paid; the borrower has equitable title and possession. Foreclosure is often faster and non-judicial.
  • Intermediate theory: A hybrid used in some states where title passes to the lender only upon default.

Exam clue: if a question says the lender merely has a lien and the borrower holds title, that describes a lien theory state, which is the majority.

Recording and Lien Priority

Security instruments are recorded in the county land records to give constructive notice to the world and to establish priority. The general rule is first to record, first in right ("first in time, first in line"). A first mortgage recorded before a second mortgage is paid first from foreclosure proceeds.

Two important exceptions:

  • Property tax and special assessment liens generally take priority over all private liens regardless of recording date.
  • A subordination agreement lets a lender voluntarily move its lien to a lower priority, commonly used so a new construction or refinance loan can take first position.

Core Mortgage Clauses

Examiners test these clauses constantly. Memorize the trigger for each.

  • Acceleration clause: On default, the lender can demand the entire unpaid balance at once. The trigger is default.
  • Alienation clause (due-on-sale): The full balance becomes due when the property is sold or transferred. The trigger is transfer. This blocks an unqualified buyer from simply assuming the loan.
  • Defeasance clause: Requires the lender to release the lien and return clear title once the debt is paid in full. The trigger is payoff.
  • Prepayment clause: States whether the borrower may pay early and whether a penalty applies.
  • Subordination clause: Allows a lien to be reordered to a lower priority.

Classic trap: a question asks which clause is triggered by a sale (alienation) versus a default (acceleration). Read the trigger word, not the outcome.

The Secondary Market and Promissory Notes

Lenders rarely hold every loan. The secondary mortgage market, led by Fannie Mae and Freddie Mac (and Ginnie Mae for government loans), buys loans from originators, replenishing cash so lenders can keep lending. This is why originators follow standardized conforming guidelines.

The Promissory Note

The note is the borrower's personal promise to repay, naming the principal, interest rate, term, and payment schedule. The mortgage or deed of trust is merely the security instrument that pledges the property as collateral.

DocumentRole
Promissory noteThe debt, the promise to pay
Mortgage / deed of trustThe security, the lien on the property

Exam trap: The note is the debt; the mortgage is the lien securing the debt. A borrower signs both, but they do different jobs.

Defeasance and Acceleration

Two note/mortgage clauses recur: a defeasance clause requires the lender to release the lien (issue a satisfaction) once the debt is fully paid, while an acceleration clause lets the lender demand the entire balance at once upon default, the prerequisite to foreclosure.

Exam trap: Acceleration makes the whole balance due on default; defeasance clears the lien at payoff. Both are standard security-instrument clauses.
