Introduction
When a lender takes collateral to secure a loan, the instrument they use depends entirely on what type of property is being pledged. Real estate is secured by a mortgage (or deed of trust). Personal property — equipment, inventory, receivables, and virtually everything else — is secured through a UCC filing under Article 9 of the Uniform Commercial Code.
The distinction sounds simple, but it creates real complexity in commercial transactions that involve both types of assets, and especially in situations involving fixtures — property that starts as personal property and becomes permanently attached to real estate.
The Fundamental Divide: What Type of Property?
| Factor | UCC Filing (Article 9) | Mortgage / Deed of Trust |
|---|---|---|
| Property Type | Personal property — tangible goods, intangibles, instruments, accounts. | Real property — land, buildings, and permanently affixed structures. |
| Governing Law | UCC Article 9 (adopted in all 50 states). | State real property law — varies significantly by state. |
| Where Recorded | Secretary of State UCC index (state-level central filing). | County recorder's office or register of deeds in the county where the property is located. |
| Perfection Method | Filing UCC-1 Financing Statement; possession; control (by asset type). | Recording the mortgage or deed of trust in the county property records. |
| Duration | 5 years; renewable by UCC-3 Continuation. | Remains effective until paid off, released, or foreclosed. No automatic expiration. |
| Enforcement on Default | Self-help repossession under Article 9 (no court required in most cases). | Judicial or non-judicial foreclosure process under state law. Court involvement usually required. |
| Priority Rule | First to file or perfect (Article 9 rules). | First to record in county records (race-notice or pure race recording acts, depending on state). |

UCC Filings: Personal Property Security
A UCC-1 Financing Statement is the public notice that a lender holds a security interest in the debtor's personal property. "Personal property" in Article 9's framework is an expansive category that includes virtually everything that is not real estate: machinery, vehicles, office equipment, raw materials, finished goods held for sale, accounts receivable, intellectual property rights, software licenses, bank deposit accounts, and more.
Filing a UCC-1 with the Secretary of State in the debtor's state of organization creates a public, searchable record of the lien. The filing does not involve the county property system at all — it is entirely separate from the real estate recording system.
Mortgages and Deeds of Trust: Real Property Security
A mortgage (or deed of trust, used in many Western states) is the instrument used to give a lender a security interest in real estate. The lender records the mortgage in the county property records where the real estate is located, creating a public lien on the specific parcel.
Unlike a UCC-1, a mortgage does not expire automatically. It remains in the property records until it is satisfied and a release (or deed of reconveyance) is recorded. Foreclosure on a mortgage requires following state-specific procedures — which can involve court proceedings and lengthy timelines depending on the state.
The Overlap Zone: Fixture Filings
The most complex area sits at the boundary between personal and real property: fixtures. A fixture is a good that was originally personal property but has become so permanently attached to real estate that property law treats it as part of the real estate. Common examples include:
- Commercial HVAC systems bolted to a building
- Elevators and escalators
- Industrial manufacturing equipment bolted to a factory floor
- Built-in commercial refrigeration units
- Electrical systems and plumbing permanently installed in a building
For fixture collateral, Article 9 provides a special mechanism called a fixture filing. A fixture filing is a UCC-1 (or UCC-3) filed in the real property records of the county where the fixture is located — not in the central state UCC index. It must include a description of the real property to which the fixture is attached.
Why does the fixture filing go in the county records? Because a competing claim on a fixture may come from a mortgage lender who holds a mortgage on the building. The fixture filing must be in the same records as the mortgage for the priority contest to be resolved properly under Article 9's fixture priority rules.
Priority Between a Fixture Filing and a Mortgage
When a UCC fixture filing and a real estate mortgage both cover the same fixture, the priority rules are more nuanced than the standard first-to-file rule:
- A purchase money security interest (PMSI) fixture filing generally takes priority over an earlier recorded mortgage, if the PMSI is filed before the goods become fixtures or within 20 days after.
- A construction mortgage (covering fixtures to be installed as part of new construction) generally has priority over later fixture filings.
- In other cases, the first-to-record rule generally applies, comparing the mortgage recording date to the fixture filing date.
Mixed Collateral Transactions: Taking Both Types of Security
Many commercial real estate loans involve both real property (the building) and personal property (equipment, fixtures, leases, rents, and other business assets). In these transactions, lenders typically use:
- A mortgage or deed of trust — to perfect the security interest in the real estate.
- An Assignment of Rents and Leases — to perfect the lender's interest in rental income and tenant leases.
- A UCC-1 Financing Statement — to perfect the security interest in personal property, equipment, and general intangibles.
- A UCC fixture filing — if any of the personal property collateral is or will become a fixture.
All four instruments working together give the commercial lender comprehensive coverage over both the real and personal property components of the transaction.
Key Takeaways
- UCC filings cover personal property. Mortgages cover real property. The type of collateral determines the instrument.
- UCC-1s are filed centrally with the Secretary of State. Mortgages are recorded in the county property records.
- UCC filings expire after 5 years and must be continued. Mortgages do not expire automatically.
- Fixtures sit at the boundary — secured by UCC fixture filings recorded in the county property records.
- Complex commercial transactions often require both a mortgage and a UCC filing to cover all collateral types.
