Summary:
Collateral is an asset a borrower pledges to a lender as security for a loan, giving the lender the right to seize and sell that asset if the borrower fails to repay.
The type of collateral required depends heavily on the loan type, and it directly influences the interest rate, loan amount, and approval odds a borrower can expect.
- Real estate: Homes and commercial properties are the most common form of collateral for mortgage loans and home equity products, given their stable value and legal enforceability.
- Vehicles: Cars, trucks, and equipment serve as collateral for auto loans and equipment financing, with the lender typically holding the title until the loan is paid.
- Financial assets: Savings accounts, CDs, stocks, and bonds can be pledged as collateral for secured personal loans or margin accounts, often enabling lower rates.
- Business assets: Inventory, accounts receivable, and machinery are commonly pledged in commercial lending when real estate collateral isn’t available.
Collateral changes the math on a loan. It gives lenders a safety net, which typically translates into better terms for the borrower. Understanding what counts as collateral and what’s at risk helps you make clearer decisions before you sign.

How collateral works in secured lending
When a lender accepts collateral, they’re not just taking your word that you’ll repay the loan. They’re taking a legally enforceable claim on a specific asset. If you default, the lender can seize the collateral, sell it, and apply the proceeds toward the outstanding debt.
According to the Consumer Financial Protection Bureau, secured loans — those backed by collateral — typically carry lower interest rates than unsecured loans because the lender’s risk is reduced by the ability to recover assets if the borrower defaults.
Secured vs. unsecured loans
The presence or absence of collateral determines whether a loan is secured or unsecured. This distinction affects nearly every term in the loan agreement.
| Feature | Secured Loan | Unsecured Loan |
|---|---|---|
| Collateral required | Yes | No |
| Typical interest rate | Lower | Higher |
| Approval with poor credit | More accessible | More difficult |
| Risk to borrower | Asset seizure if default | Credit damage, collections |
| Loan amounts | Often higher | Usually lower |
| Examples | Mortgage, auto loan, HELOC | Personal loan, credit card |
How lenders value collateral
Lenders don’t lend the full market value of pledged collateral. They apply a loan-to-value ratio, lending a percentage of the asset’s appraised value to create a buffer against market fluctuations or selling costs.
For a home, most lenders will lend up to 80% of the appraised value through a primary mortgage. For a home equity line of credit, combined borrowing may be capped at 85% to 90% of the home’s value. For financial assets like stocks, margin lending is typically limited to 50% of the portfolio value.
The gap between the asset’s value and the loan amount, sometimes called “equity” or “overcollateralization,” protects the lender if asset values decline before they can sell the collateral. See how this plays out in mortgage lending at our entry on loan-to-value ratio.
Pro Tip
If you have a savings account or CD, you can often use it as collateral for a secured personal loan at the same bank. These “share-secured” or “passbook loans” frequently carry rates just a few percentage points above the deposit’s rate. This can be an effective way to build credit or access liquidity without breaking a CD early, since the deposit remains intact and earns interest while the loan is outstanding. According to our personal loans interest rate study, secured personal loans consistently carry lower APRs than their unsecured equivalents across all credit tiers.
What happens if you default on a secured loan
Defaulting on a secured loan triggers a legal process that varies by loan type and state law. For mortgages, this means foreclosure. For auto loans, this means repossession. For loans secured by financial accounts, the lender may liquidate the pledged assets.
After the collateral is sold, the proceeds are applied to the outstanding debt. If the sale price doesn’t cover what’s owed, the borrower may still be liable for the remaining balance, called a “deficiency judgment,” depending on state law and loan terms.
Good to know: Some states are “non-recourse” states for purchase-money mortgages, meaning the lender can only seize the property and cannot pursue the borrower for any deficiency after foreclosure. California is one notable example. The rules differ for refinanced mortgages and home equity loans even in non-recourse states.
Using home equity as collateral
Home equity is among the most powerful forms of collateral for individual borrowers because it’s typically large, appreciates over time, and gives lenders a high degree of confidence in recovery. Two common products use home equity as collateral:
- A home equity loan provides a lump sum at a fixed rate, using your equity as collateral for a second mortgage.
- A home equity line of credit (HELOC) functions like a revolving line of credit backed by your home, with a draw period followed by a repayment period.
Both put your home at risk if you can’t repay, so they’re best used for productive purposes like home improvements or consolidating higher-rate debt rather than discretionary spending.
How to use collateral to get a secured loan
- Identify what assets you have available: Consider real estate, vehicles, savings accounts, CDs, investment accounts, or business assets. Each asset class has different borrowing limits and processes.
- Get the asset appraised or valued: Lenders need a current value to determine how much they’ll lend. For real estate, this means a formal appraisal. For financial accounts, the current balance is used.
- Compare lenders: Secured loan rates and LTV limits vary by lender. Shop at least three to four options before committing, especially for larger loan amounts.
- Review the security agreement: This is the document that formally grants the lender a claim on your asset. Read it carefully — it defines what triggers default and what the lender can do in response.
- Confirm your plan for repayment: Collateral reduces the lender’s risk, but your risk increases. Make sure the monthly payment is sustainable before pledging an asset you can’t afford to lose.
Using collateral thoughtfully can open access to financing that wouldn’t otherwise be available, at terms you wouldn’t otherwise qualify for. The tradeoff is real: the asset is at stake if circumstances change.

Frequently asked questions
Can I use collateral to get a loan with bad credit?
Yes. Secured loans are generally more accessible to borrowers with poor or limited credit history because the collateral reduces the lender’s risk. The asset’s value and the lender’s ability to recover it matter more than your credit score in many secured lending scenarios, though credit still affects the rate you’re offered.
What is cross-collateralization?
Cross-collateralization is a clause in some loan agreements, common with credit unions, that allows the lender to claim one asset as collateral for multiple loans. For example, a car loan and a credit card from the same credit union might both be secured by your car under such a clause. Read loan agreements carefully to identify these provisions.
Can collateral be something other than real estate or vehicles?
Yes. Collateral can include savings accounts, CDs, investment portfolios, life insurance cash value, artwork, jewelry, and business assets like inventory or accounts receivable. The asset must have a verifiable value and be sellable if the lender needs to recover funds.
Does pledging collateral affect my credit score?
Pledging collateral itself doesn’t directly affect your credit score. However, applying for a secured loan typically triggers a hard credit inquiry, which may cause a small, temporary dip. Making on-time payments on the secured loan helps build your credit over time, and defaulting causes significant damage.
What’s the difference between collateral and a guarantee?
Collateral is a specific asset pledged to the lender. A personal guarantee is a promise by an individual to repay the debt if the primary borrower defaults, without tying it to a specific asset. Lenders often require both for business loans, particularly for small businesses without substantial assets.
