Being “secured” is a legal status, not a feeling. A lender is secured only if it holds a valid security interest, has perfected it so that it is effective against other creditors, ranks ahead of competing claims and can, in practice, realize the collateral. This entry explains how that is achieved in US lending, at a general level, and how guarantees supplement it. Specific questions belong with counsel.
Our published collateral is real and financial assets: commercial real estate, industrial equipment, corporate receivables, fund NAVs and other financial assets. Our criteria exclude “loans backed by collateral we cannot value or, if necessary, take control of and realize.” See our criteria.
Attachment, perfection and priority
- Attachment makes the security interest enforceable against the borrower. Under Article 9 of the Uniform Commercial Code (UCC), it generally requires value given, the borrower’s rights in the collateral and a signed security agreement describing it.
- Perfection makes it effective against third parties, including a bankruptcy trustee. The method depends on the collateral.
- Priority decides who ranks first among creditors with interests in the same collateral. The usual rule is first to file or perfect, subject to important exceptions such as purchase-money interests and certain statutory liens.
A senior secured lender wants all three: attached, perfected and first in priority.
How different collateral is perfected
| Collateral | Security document | Main method of perfection |
|---|---|---|
| Real estate | Mortgage or deed of trust | Recording in the county land records; title insurance confirms priority |
| Receivables, inventory, equipment, general intangibles | Security agreement | UCC-1 financing statement filed in the borrower’s state of organization |
| Deposit accounts | Deposit account control agreement (DACA) | Control: the bank agrees to follow the lender’s instructions |
| Securities accounts | Securities account control agreement | Control |
| Equity in LLCs and partnerships | Pledge agreement | UCC filing; control if the interests are opted into Article 8 and certificated |
| Titled vehicles | Security agreement | Notation on the certificate of title |
| Intellectual property and royalties | Security agreement, often with IP filings | UCC filing plus recording with the Patent and Trademark Office or Copyright Office where relevant |
Before closing, the lender runs lien, judgment and tax searches to confirm there are no competing interests, and obtains payoff letters and releases for any existing lender.
Real estate security
A mortgage or deed of trust gives the lender a lien on the property, recorded in the land records. A lender’s title insurance policy insures the lien’s validity and priority, subject to listed exceptions. Lenders typically also take an assignment of leases and rents, so they can collect rent directly after a default, and require an ALTA survey, zoning review, property and liability insurance naming the lender, and environmental review. For construction loans, mechanics’ liens can in some states take priority over a later-recorded mortgage, which is one reason draws require lien waivers and title date-downs. See Real estate bridge and construction loans.
Equity pledges and structural position
Sometimes a lender takes a pledge of the equity in the entity that owns the asset, rather than, or in addition to, a mortgage. This is the usual structure for mezzanine loans. Enforcement by a UCC sale of the equity can be faster than foreclosure, but the lender acquires the entity with its liabilities, and it ranks behind any lender with a direct lien on the asset. See The capital structure and why seniority matters.
Guarantees
A guarantee is a promise by a third party, usually a parent, sponsor or principal, to answer for the borrower’s obligations. Guarantees vary widely in scope.
| Guarantee | What the guarantor promises | Where it is common |
|---|---|---|
| Full payment guarantee | To pay the loan if the borrower does not | Smaller corporate loans; owner-operated businesses |
| Limited or capped guarantee | To pay up to a set amount or share | Negotiated middle ground |
| Non-recourse carve-out (“bad-boy”) | To be liable for losses, or the full loan, if specified bad acts occur: fraud, misappropriation, unpermitted transfers, voluntary bankruptcy | Commercial real estate loans that are otherwise non-recourse |
| Completion guarantee | To complete construction on budget, funding cost overruns | Construction and heavy renovation loans |
| Carry guarantee | To fund interest, taxes, insurance and operating shortfalls until stabilization | Bridge and construction loans |
| Environmental indemnity | To cover environmental liabilities | Real estate loans |
| Upstream guarantees by subsidiaries | Group companies guarantee the borrower’s debt and pledge their assets | Corporate loans to holding company structures |
Project Juniper is a case study that uses carry guaranties alongside an interest reserve.
What a guarantee is worth
A guarantee is worth what the guarantor can pay when it is called, which is often a time of stress for the guarantor too. Lenders typically require financial covenants on the guarantor, such as minimum net worth and liquidity, and periodic financial statements. A carve-out guarantee is often more valuable for the behavior it encourages than for the money it might recover: a sponsor with personal exposure to a voluntary bankruptcy filing is unlikely to file one to frustrate the lender.
Other credit support
- Reserves held by the lender: interest, capital expenditure, tenant improvement and leasing commission reserves.
- Letters of credit from a bank, drawable on demand.
- Cash collateral pledged to the lender.
- Cross-collateralization: several assets securing one loan, so that the strong carry the weak. Project Heritage is a case study of a cross-collateralized portfolio loan.
- Assignments of key contracts: construction contracts, management agreements, offtake or take-or-pay contracts, so the lender can step in. See Project Lattice.
Collateral perfection checklist (illustrative)
- Organizational documents and good-standing certificates for each obligor.
- Lien, judgment, tax and litigation searches in the right jurisdictions.
- Security agreement, mortgage, pledge and control agreements signed.
- UCC-1 filings made in the correct state and recorded mortgages confirmed.
- Title policy issued with acceptable exceptions.
- Insurance endorsements naming the lender as mortgagee or loss payee.
- Payoff and release of any prior lender.
- Landlord, bailee or warehouse waivers where collateral sits on third-party premises.
Common pitfalls
- Filing in the wrong state, or under a name that does not match the borrower’s registered name exactly.
- Missing a change of name or jurisdiction after closing, which can lapse perfection.
- Failing to continue a UCC filing before it lapses, generally after five years.
- Collateral held at locations the lender does not know about.
- Relying on a guarantee from someone whose assets are themselves pledged.
