Almost any asset you fully own and a lender could resell can be used as collateral for a loan. That includes real estate, vehicles, cash and CDs, publicly traded securities, business inventory and receivables, life insurance policies, and, in narrower cases, intellectual property. A few assets are off the table by federal law, most importantly 401(k)s, IRAs, and Social Security benefits.
What Makes an Asset Acceptable
Lenders judge potential collateral against three practical tests. You need clear ownership, with no competing claim that would block a new lender from taking a first-priority position. The asset needs to be reasonably liquid, meaning it can be sold at a fair price within a reasonable timeframe. And there has to be a legal way to record the lender’s claim, whether that’s a lien filed with the county for real estate or paperwork filed with the state for personal and business property.
The stronger an asset scores on all three, the more a lender will lend against it and the better your rate will be. 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 sits somewhere between those two extremes.
Real Estate
Real estate is the most widely accepted collateral for large loans. It doesn’t move, ownership is a matter of public record, and values tend to hold up. Residential property secures standard mortgages; commercial buildings and undeveloped land back business loans. In each case the lender records a lien at the county recorder’s office, which fixes priority if you default.
Lenders size their exposure using the loan-to-value ratio (LTV), which compares the loan amount to the property’s 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 until you build enough 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 at 78%.1Office of the Law Revision Counsel. 12 US Code 4902 – Termination of Private Mortgage Insurance
If you’ve built substantial equity, you can tap it through a home equity line of credit (HELOC) or a second mortgage. These sit behind the original mortgage in priority, which is why they carry higher rates than a first mortgage.
Cash, CDs, and Investment Securities
Cash equivalents like certificates of deposit and savings accounts are the cleanest collateral a lender can get. The value is stable, easy to verify, and instantly convertible. The lender secures its interest through a deposit control agreement that keeps you from withdrawing the funds without its consent. Because the risk is so low, these loans often carry rates only slightly above the deposit’s own yield.
Publicly traded stocks, bonds, and mutual funds can also secure loans, often called securities-backed lines of credit. The lender holds 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 That ceiling exists because stock prices can drop fast. If the portfolio’s value falls below a maintenance threshold, you’ll face a margin call requiring more assets or a paydown. Investment-grade bonds and government securities get more generous treatment because their prices are less volatile.
Vehicles and Personal Property
Cars, trucks, boats, and recreational vehicles are common collateral for installment loans. The lender’s interest is recorded with the state motor vehicle agency, either noted on the title or logged electronically, and that recorded lien prevents you from selling the vehicle without first paying off the debt.
In business lending, machinery, manufacturing equipment, and specialized tooling frequently secure equipment financing. The loan term usually matches the asset’s expected useful life. High-value personal items like fine art, rare collectibles, and investment-grade jewelry can also work, but lenders approach them cautiously because appraisal takes specialized expertise and the resale market is narrow.
The core problem with personal property is depreciation. A new car loses value the moment you drive it off the lot, and most equipment follows a similar path. Lenders account for this by lending conservatively against current value, and they may require you to keep insurance on the collateral for the life of the loan. If your coverage lapses on a financed asset, the lender can buy force-placed insurance and charge you for it, though federal rules require written notice at least 45 days before imposing the charge, a second notice, and a 15-day window for you to prove you’ve restored coverage.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.
Business Inventory and Accounts Receivable
Businesses that need working capital often lack a single high-value asset to pledge. Instead they offer inventory, unpaid invoices, or both. The complication is that inventory sells and receivables get paid, so the specific items serving as collateral are constantly changing. The legal fix is a floating lien, which automatically attaches to new inventory and new receivables as they replace the old ones. 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 single item.4Cornell Law Institute. UCC 9-315 – Secured Party Rights on Disposition of Collateral
The lender perfects this 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 specific item.
Life Insurance Policies
A life insurance policy can serve as collateral through a collateral assignment. You designate the lender as an assignee on the policy, giving it 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 over still 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, but some lenders prefer permanent policies (whole life or universal life) because they accumulate cash value. That cash value gives the lender a second layer of protection: even if you default while alive, it can access the policy’s cash surrender value. If you already have significant cash value, you might also borrow directly from the insurer against it rather than going through a bank, though unpaid policy loans reduce the death benefit.
Intellectual Property
Patents, trademarks, and copyrights can all secure loans, though the process is trickier than pledging a building or a brokerage account. Under the UCC, intellectual property is treated as a “general intangible,” and security interests in most IP can be perfected by filing a UCC-1 with the state. Copyrights are the exception: federal law requires that security interests in registered copyrights be recorded with the U.S. Copyright Office rather than through the state UCC system.
The hard part is valuation. A patent’s worth depends on the technology it protects, its remaining life, licensing revenue, and the cost of enforcing it. Trademarks are tied to brand recognition and ongoing business operations. Lenders willing to accept IP collateral tend to be specialty firms, not traditional banks, and the loans typically carry higher rates and lower advance rates.
What You Cannot Pledge
Federal law puts several categories of assets completely off-limits, and this is where people run into trouble.
- Qualified retirement plans. Employer-sponsored 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 limits the plan allows.5Office of the Law Revision Counsel. 29 US Code 1056 – Form and Payment of Benefits
- Individual Retirement Accounts. IRAs aren’t covered by ERISA the same way, but the tax code imposes 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 that 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. Federal law flatly prohibits the transfer or assignment of Social Security benefits. They cannot be seized through garnishment, levy, or attachment by private creditors, and they cannot be pledged as collateral for any loan.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 side is willing to sign.
How Much You Can Actually Borrow Against Collateral
A lender never gives you dollar-for-dollar credit for your collateral’s 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, live market quotes for securities). The lender then applies a discount, called a haircut, to create a buffer against price declines. If your car is worth $30,000 today but might fetch only $22,000 at auction six months from now, the loan is based on something closer to that lower figure.
The size of the haircut reflects how volatile and liquid the asset is. 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 typically run from 20% to 40% depending on the property and location. Art, collectibles, and niche business 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’s at Stake if You Default
The lender’s right to seize and sell your collateral is the whole point of a secured loan. Real estate goes through foreclosure, judicial or nonjudicial depending on the state. Vehicles get repossessed. Financial accounts get liquidated. In every case, the lender applies the sale proceeds to the outstanding balance, and in most states you remain responsible for any shortfall.
The costs go beyond losing the asset. Lenders routinely add legal fees, property inspection charges, and preservation costs to your loan balance during the default and foreclosure process, and those charges are often recoverable under the original loan contract. The amount you owe can grow substantially between the first missed payment and the final resolution, which is worth weighing before you pledge an asset you can’t afford to lose.
