Using your home as collateral means signing a loan agreement that gives the lender a recorded legal claim on your property. In exchange, you typically get a lower interest rate than an unsecured loan would carry. The tradeoff is direct: if you stop paying, the lender can force a sale of your home to recover what you owe. Before you sign anything, you should understand which loan products put your house on the line, what the lien on your title actually restricts, how much you can borrow, and what default looks like in practice.
The Three Loans That Put Your House on the Line
Home Equity Loan
A home equity loan pays out a single lump sum at closing, which you repay over a fixed term at a fixed interest rate.1Federal Trade Commission. Home Equity Loans and Home Equity Lines of Credit The monthly payment doesn’t move. That predictability makes it a common pick for one large, known expense: a renovation with a firm bid, or consolidating high-rate debt. You take the full amount upfront whether you need it all right away or not, and you start paying interest on the whole balance from day one.
Home Equity Line of Credit (HELOC)
A HELOC is a revolving credit line secured by your property. The lender sets a maximum limit, and during the draw period you borrow against it as needed, paying interest only on what you’ve actually taken out.2Consumer Financial Protection Bureau. What Is a Home Equity Line of Credit (HELOC)? Most HELOCs carry a variable rate, so the payment can rise or fall month to month.3Federal Trade Commission. Home Equity Loans and Home Equity Lines of Credit The flexibility fits ongoing or unpredictable costs, but you need to budget for the possibility that rates and payments climb during the loan.
Cash-Out Refinance
A cash-out refinance replaces your existing mortgage with a new, larger one and pays you the difference in cash. Where a home equity loan or HELOC sits behind your primary mortgage as a second lien, a cash-out refinance becomes your only mortgage and leaves you with one monthly payment. Because the lender holds the first claim on the property, the rate is often lower than on second-lien products. The catch is that you’re resetting the mortgage clock: refinancing a loan with ten years left into a new thirty-year term stretches your total repayment out considerably.
What the Lien Actually Does to Your Ownership
At closing, the lender records a lien against your title with the local government. It’s a legal notice that the lender has a stake in your home until the loan is paid off. You keep living in the house and using it as normal, but the lien creates real constraints.
Selling gets more complicated. Every lien has to be paid from the sale proceeds before you see a dollar. If you have a primary mortgage and a home equity loan, both lenders come first. If the sale doesn’t cover both balances, you’re generally still responsible for the shortfall. The lien stays on the title until the loan is fully repaid, at which point the lender files a release removing the claim.
The lien is also what gives the lender the legal authority to foreclose if you stop paying. Without it, they’d be in the position of an unsecured creditor: able to sue you for the debt but unable to take the house.
How Much You Can Borrow and What Qualifies You
Three numbers drive the offer: your equity, your credit, and your existing debt load.
- Loan-to-value ratio (LTV). Most lenders cap combined LTV at around 80% to 85% of the appraised value. On a $400,000 home with $250,000 still owed on the primary mortgage, an 80% cap allows up to $70,000 on a second lien: $400,000 × 0.80 comes to $320,000, minus the $250,000 already borrowed. Higher LTV limits exist but usually cost you in rate.
- Credit score. A minimum around 620 is common, though some lenders require 660 or higher. Stronger scores unlock better rates and larger limits.
- Debt-to-income ratio (DTI). Lenders prefer total monthly debt payments, including the new loan, at or below 36% of gross monthly income. Some will stretch to 43% for borrowers with strong credit and stable employment. Past that range, denials become the norm.
The lender will also order a professional appraisal to confirm current market value. You pay the fee, which typically runs $350 to $550 for a standard single-family home.4FDIC. Understanding Appraisals and Why They Matter The appraised value sets the ceiling on what the lender will lend.
Costs at Closing and Your Right to Back Out
Closing costs on a home equity loan typically run 2% to 5% of the loan amount. They cover the lender’s origination work (usually 0.5% to 1% of the loan), a title search ($75 to $200), the appraisal, a credit report pull ($30 to $50), and recording and notary fees that vary by county. HELOCs often carry lower upfront costs, and some lenders waive them entirely, though that cost is often recovered through a higher rate or an early-closure fee if you shut the line down in the first few years.
Federal law then gives you a cooling-off period. After closing on a home equity loan, HELOC, or the cash-out portion of a refinance, you have until midnight of the third business day to cancel the transaction for any reason.5Office of the Law Revision Counsel. 15 USC 1635 – Right of Rescission as to Certain Transactions The lender is required to give you a notice explaining the right and two copies of a cancellation form. If they don’t, your window to cancel can extend up to three years.6eCFR. 12 CFR 1026.15 – Right of Rescission To use it, you notify the lender in writing before the deadline. Within 20 days, the lender must return any fees you paid and release its claim on your property.7Consumer Financial Protection Bureau. Regulation Z 1026.23 – Right of Rescission
One boundary worth naming: rescission does not apply to a mortgage used to purchase a home. It’s a protection for loans that put an existing home at risk, not for the loan that buys the house in the first place.
What Default Actually Looks Like
The Foreclosure Timeline
Missing payments is where the danger of a home-secured loan turns concrete. Federal rules bar your servicer from beginning foreclosure until you’re more than 120 days past due.8eCFR. 12 CFR 1024.41 – Loss Mitigation Procedures During that window, the servicer must reach out with options to avoid foreclosure, such as a loan modification or repayment plan.
If the delinquency isn’t resolved, the lender files a notice of default and the formal process begins. Timelines vary sharply by state. Judicial-foreclosure states route the case through the courts and can take a year or more. Non-judicial states move faster. Either way, the end point is the same: a forced sale of your home, with the proceeds applied to the debt.
Deficiency Judgments
If the sale doesn’t bring in enough to cover the balance, the shortfall is called a deficiency. In most states, the lender can sue you for it and obtain a judgment requiring payment. A handful of states either prohibit deficiency judgments entirely or restrict them to certain kinds of foreclosure. This matters when home values have fallen: the gap between what you owe and what the home sells for can be significant, and losing the house doesn’t automatically end the debt.
Credit Damage
A completed foreclosure stays on your credit report for seven years.9Consumer Financial Protection Bureau. Impact of Foreclosure on Credit Report The score hit is severe: borrowers around 680 typically drop 85 to 105 points, and those starting near 780 can lose 140 to 160. Most conventional mortgage programs then impose a three-to-seven-year waiting period before you can qualify for a new loan.
The damage starts earlier than foreclosure. Each 30-day-late mark is reported separately, and the effects compound as you fall further behind, so a home-secured loan gone wrong hurts your credit long before any legal action is filed.
Whether the Interest Is Tax-Deductible
Whether you can deduct interest on a home-secured loan depends on how you spend the borrowed money. For tax year 2026, with the expiration of temporary limits that applied from 2018 through 2025, the rules are more favorable than in recent years.
Interest on debt used to buy, build, or substantially improve your home is deductible on up to $1,000,000 of combined mortgage debt, or $500,000 if married filing separately.10Internal Revenue Service. Publication 936 – Home Mortgage Interest Deduction Starting in 2026, interest on home equity debt used for other purposes, such as paying off credit cards or funding education, is again deductible on up to $100,000 of that debt ($50,000 if married filing separately). From 2018 through 2025, that second category was suspended, and home equity interest was deductible only when the proceeds went into improving the home that secured the loan.11Internal Revenue Service. Real Estate (Taxes, Mortgage Interest, Points, Other Property Expenses)
The deduction only helps if you itemize. If your standard deduction is larger than your total itemizable expenses, the interest write-off delivers no actual tax benefit, and any calculation of the loan’s true cost should reflect that.
