Almost any asset you fully own with a measurable market value can be used as collateral for a loan: real estate, vehicles, cash accounts, publicly traded securities, business inventory and receivables, life insurance policies, and even patents and trademarks. The items that can be used as collateral for a loan share three traits a lender looks for, and a short list of assets, including 401(k)s, IRAs, and Social Security benefits, are blocked by federal law no matter what you and the lender agree to.
What Makes an Asset Acceptable
Lenders run every pledge through three practical tests. You need clear ownership, with no competing lien that would push a new lender out of first position. The asset has to be reasonably liquid, meaning the lender can sell it at a fair price within a reasonable time if you default. And there must be a legal mechanism to record the lender’s claim: a county recording for real estate, a state filing for personal and business property, a title notation for vehicles, or a control agreement for a brokerage account. Without that public record, the lender has no enforceable priority over other creditors.
The stronger an asset scores on all three, the more a lender will advance against it and the better your rate. Cash in a savings account checks every box. A one-of-a-kind painting does not, because finding a buyer takes time and the price is subjective. Most collateral lands somewhere between.
Real Estate
Real estate is the most widely accepted collateral for large loans. It doesn’t move, ownership sits in public records, and values tend to hold up. Residential property secures standard mortgages; commercial buildings and raw land back business loans. The lender records a lien against the deed at the county recorder’s office, which fixes priority if you default.
Lenders size their exposure with the loan-to-value ratio (LTV), which compares the loan to the appraised value. Most conventional residential mortgages target an LTV of 80% or below. If your down payment doesn’t get you there, you’ll typically pay private mortgage insurance (PMI) until you build equity. Under the Homeowners Protection Act, you can request PMI cancellation once the principal balance reaches 80% of the home’s original value, and the servicer must automatically terminate PMI when the balance hits 78%.1Office of the Law Revision Counsel. 12 US Code 4902 – Termination of Private Mortgage Insurance
If you already have equity, you can tap it through a home equity line of credit (HELOC) or a second mortgage. These sit behind the original mortgage, so the first lender gets paid first in a foreclosure sale. That second-position risk is why HELOCs and second mortgages carry higher rates than primary mortgages.
Cash, CDs, and Securities
Cash equivalents like certificates of deposit and savings accounts are the cleanest collateral a lender can get. Value is stable, verification is instant, and conversion to cash is immediate. The lender typically uses a deposit control agreement, which blocks you from withdrawing the funds without consent. Because the risk is so low, loans backed by cash equivalents often price only slightly above the deposit’s own yield.
Publicly traded stocks, bonds, and mutual funds can also secure loans, usually called securities-backed lines of credit. The lender takes control of the portfolio in a restricted brokerage account. Under Federal Reserve Regulation T, brokers can lend up to 50% of the current market value of equity securities.2Financial Industry Regulatory Authority. Margin Regulation The 50% ceiling exists because stock prices can drop fast. If the portfolio’s value falls below a maintenance threshold, you’ll face a margin call to deposit more assets or pay down the balance. Investment-grade bonds and government securities get more generous treatment because their prices are less volatile.
Vehicles and Personal Property
Titled goods, including cars, trucks, boats, and recreational vehicles, routinely secure installment loans. The lien is recorded with the state motor vehicle agency, either on the physical title or electronically, which stops you from selling the vehicle before the loan is cleared.
In business lending, heavy machinery, manufacturing equipment, and specialized tooling secure equipment financing, usually on a term that matches the asset’s useful life. High-value personal items like fine art, rare collectibles, and investment-grade jewelry can also be pledged, but lenders approach them cautiously. Appraisal takes specialized expertise, the resale market is narrow, and “fair value” is often debatable.
The underlying problem with personal property is depreciation. A new car loses value the moment it leaves the lot, and most equipment follows a similar curve. Lenders compensate by advancing conservatively and may require you to maintain insurance on the collateral for the life of the loan. If coverage lapses on a financed asset, the lender can purchase force-placed insurance on your behalf and charge you for it, after sending written notice at least 45 days before imposing the charge.3Consumer Financial Protection Bureau. 12 CFR 1024.37 – Force-Placed Insurance Force-placed policies are almost always more expensive than one you’d buy yourself, so letting coverage lapse is a costly mistake.
Business Inventory and Accounts Receivable
Businesses that need working capital often lack a single high-value asset to pledge. Instead, they offer their inventory, their unpaid invoices (accounts receivable), or both. The complication is that inventory sells and receivables get paid, so the specific items serving as collateral are constantly turning over. The legal fix is a floating lien, which automatically attaches to new inventory and new receivables as they replace the old. Under the Uniform Commercial Code, a security agreement can cover after-acquired collateral, so the lender’s interest follows the stream of assets rather than any individual item.4Cornell Law Institute. UCC 9-315 – Secured Party Rights on Disposition of Collateral
The lender perfects by filing a UCC-1 financing statement with the state, often describing the collateral broadly as “all inventory and accounts receivable, now owned or hereafter acquired.” If you default, the lender can notify your customers to redirect their payments. From a borrower’s perspective, a floating lien gives the lender a sweeping claim across your operations, not just a claim on one piece of property.
Life Insurance Policies
A life insurance policy can be pledged through a collateral assignment. You name the lender as an assignee, giving them the right to collect from the death benefit if you die before the loan is repaid. The lender can only claim the outstanding balance; anything left goes to your named beneficiaries. Once the loan is paid off, the assignment is released and the policy reverts entirely to you.
Both term and permanent policies can be assigned, though some lenders prefer permanent policies (whole life or universal life) because they build cash value. That cash value gives the lender a second layer of protection: even if you default while alive, the lender can reach the policy’s cash surrender value. If your permanent policy has significant cash value, you might borrow directly from the insurer against it rather than going to a bank, though unpaid policy loans reduce the death benefit.
Intellectual Property
Patents, trademarks, and copyrights can secure loans, though the process is more involved than pledging a building or a brokerage account. Under the UCC, intellectual property falls under “general intangibles,” and security interests in most IP are perfected by a UCC-1 filing with the state. Copyrights are the exception: federal law requires security interests in registered copyrights to be recorded with the U.S. Copyright Office rather than through the state UCC system.
The practical obstacle is valuation. A patent’s worth depends on the technology it protects, remaining life, licensing revenue, and the cost of enforcement. Trademarks are tied to brand recognition and ongoing operations. Lenders who accept IP collateral tend to be specialized firms, not traditional banks, and they typically charge higher rates and advance less to compensate for the difficulty of liquidating these assets.
What You Cannot Pledge
Federal law places several categories of assets completely off-limits, and this is where borrowers often get tripped up.
- Employer-sponsored retirement plans like 401(k)s and pensions are protected by ERISA’s anti-alienation rule, which prohibits assigning or pledging plan benefits as collateral. The only exception is a loan from the plan itself to the participant, within the plan’s limits.5Office of the Law Revision Counsel. 29 US Code 1056 – Form and Payment of Benefits
- Individual Retirement Accounts aren’t covered by ERISA the same way, but the tax code supplies its own penalty. If you pledge any portion of an IRA as security for a loan, the pledged amount is treated as a taxable distribution for the year, triggering income tax and potentially a 10% early-withdrawal penalty if you’re under 59½.6Office of the Law Revision Counsel. 26 US Code 408 – Individual Retirement Accounts
- Social Security benefits cannot be transferred, assigned, garnished, levied, or pledged for any loan. The prohibition is absolute.7Office of the Law Revision Counsel. 42 US Code 407 – Assignment of Benefits
No private agreement between you and a lender can override these federal restrictions, regardless of what either party might be willing to sign.
How Much You Can Actually Borrow Against Collateral
A lender never gives you dollar-for-dollar credit for market value. Valuation starts with an appraisal: a formal third-party assessment for real estate, a standardized guide like Kelley Blue Book or NADA for vehicles, or live market quotes for securities. From there, the lender applies a discount, called a haircut, to create a buffer against price drops. If your car is worth $30,000 today but might fetch only $22,000 at auction six months from now, the lender bases the loan on something closer to the lower figure.
The size of the haircut reflects volatility and liquidity. Cash and CDs get little to no haircut. Publicly traded equities typically get a 50% haircut, matching the Regulation T initial margin limit.8eCFR. 12 CFR 220.12 – Margin Requirements Real estate haircuts generally run 20% to 40% depending on property type and location. Art, collectibles, and niche equipment take the deepest discounts because the resale market is small and unpredictable. Don’t expect to borrow the full appraised value of anything you pledge.
What Happens If You Default
Seizing and selling the collateral is the whole point of a secured loan. The process varies by asset: real estate goes through foreclosure (judicial or nonjudicial depending on the state), vehicles are repossessed, and financial accounts are liquidated. In each case, the lender applies the sale proceeds to your balance, and in most states you remain on the hook for any shortfall (a deficiency).
Costs pile up during a default beyond the loss of the asset itself. Legal fees, property inspection charges, and preservation costs are routinely added to the loan balance under the original contract, so the amount owed can grow substantially between the first missed payment and the final resolution.
Filing for bankruptcy changes the picture. The moment a petition is filed, an automatic stay takes effect, immediately halting all collection activity, including foreclosure, repossession, and lien enforcement.9Office of the Law Revision Counsel. 11 US Code 362 – Automatic Stay The stay is triggered by the filing itself, with no court order needed. Secured creditors can ask the bankruptcy court to lift the stay and proceed against the collateral, but until the court grants that request, the lender cannot touch the asset.
