The Quick Read: It depends on how much cash you need and how much you value the first mortgage you already have. A second lien leaves that first loan untouched and adds a separate loan behind it. A cash-out refinance pays the first loan off and replaces it with a larger one. For most lock-in homeowners, a modest draw points toward the second lien and a large draw points toward the refinance. Both are subject to lender guidelines and full file review.
The honest answer comes down to what you are protecting. If your current first mortgage is better than anything on offer today, a second lien keeps it. If you need a large sum, or the first loan has no special value, a cash-out refinance gives you one loan and one payment. Neither is cheaper in every case. The right pick depends on the size of the draw, your equity, and how long you plan to keep the loan.
Side-by-Side
Here is how the two options compare on the points that decide most files. The figures come from the programs Lendmire’s wholesale network places. Each one is subject to lender guidelines.
| Factor | Cash-Out Refinance | Second Lien (HELOC or Home Equity Loan) |
|---|---|---|
| What happens to your first mortgage | Paid off and replaced | Stays in place, untouched |
| Number of loans after closing | One | Two |
| Leverage, one-unit primary home | Typically up to 80% LTV | Combined leverage tested against value; limits vary by lender |
| Leverage, 2-4 units, second home | Typically up to 75% LTV | Varies by lender and occupancy |
| Credit floor | Conventional programs start at a 620 decision score | Often set higher by individual lenders |
| Mortgage insurance | Rarely at 80% or below | Not a standard feature |
| Occupancy | Primary residence, second home or investment property, depending on the program | Varies by lender |
| Seasoning | First loan 12 months old; 6 months on title | Varies by lender |
| Appraisal | New appraisal required | Appraisal or valuation, lender-dependent |
| Documentation | Full income, asset, credit file | Full file in most cases; tests combined leverage |
A few rows deserve a closer look. On a conventional cash-out, the first mortgage being paid off must be at least 12 months old, counted from note date to note date. A borrower must also have been on title for 6 months, with exceptions for delayed financing, inheritance and legal awards. The leverage caps appear in the Fannie Mae Eligibility Matrix.
How Each Option Actually Works
A cash-out refinance is one transaction. The new loan pays off the old first mortgage, covers closing costs, and puts the extra cash in your hands. That means the whole balance moves to new terms, not only the new money. For a lock-in homeowner, that is the cost: the favorable term on the old loan goes away.
You can see Lendmire’s cash-out refinance programs for the leverage and seasoning rules in one place. Across the wholesale programs placed there, a one-unit primary residence reaches 80% LTV. Two- to four-unit homes, second homes and investment property sit at 75%. One wholesale lane reaches 89.99% LTV with no mortgage insurance. It needs a 680 score and a 50% ratio on a thirty-year fixed, primary residence, conforming balance, with its own six months of seasoning. That lane is not written in Texas, where state law caps homestead cash-out. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
A second lien works differently. It is a separate loan secured by the same house, junior to the first. The first mortgage stays exactly as it is. The federal consumer-finance regulator explains that these loans often carry higher interest rates than first mortgages, because the second lender is paid second if the home is sold to settle debts. It also notes that if you cannot repay a home equity loan or HELOC, you could lose your home.
There are two common second-lien types. A home equity loan is a lump sum, usually repaid on a set schedule. A HELOC is a revolving line you draw on and repay over time. The payment on a HELOC can move. That matters when you plan the monthly budget.
When a Cash-Out Refinance Is the Better Fit
A cash-out refinance fits when the draw is large relative to your equity, or when the first loan is no longer worth protecting. Here are the common cases.
- You need a big lump sum. A single larger loan can be easier to size than a second lien stacked on top of an existing balance.
- Your first mortgage is not far below current market terms. If keeping the old loan saves little, replacing it costs little.
- You want one payment. Two loans mean two payments, two statements and two sets of terms.
- You plan to hold the loan for years. A full closing costs more up front. A longer hold gives that cost time to even out.
- You want a fixed term across the whole balance. A HELOC payment can change. A fixed first mortgage does not.
The catch: the new loan reprices the whole balance and can reset the term. You also go through a full new closing, including a new appraisal.
On leverage, lenders typically want you to keep some equity in the home. The CFPB’s home equity guide gives that retained share as 10% to 20%. You cannot borrow 100% of your equity under either option.
When a Second Lien Is the Better Fit
A second lien fits when the first mortgage is worth more to you than the convenience of one loan. This is the classic lock-in case.
- The first loan has a term you do not want to give up. The second lien leaves it alone.
- The draw is small or staged. A HELOC lets you borrow as you go, not all at once.
- You expect to repay the draw soon. A shorter horizon can favor the loan with fewer upfront steps.
- You want to avoid resetting the term. The first loan keeps its remaining years.
The trade-off is real. You carry two payments. The new money may cost more than a first mortgage would. A HELOC may also carry maintenance or other fees even when the line sits unused, per the CFPB’s HELOC brochure. That same brochure says a HELOC generally must be paid off in full when you sell.
Two file mechanics catch people off guard. First, lenders count the full credit limit of a HELOC, not just the drawn balance, when they test combined leverage. A line you never touched still counts. Second, some lenders simply do not write junior liens behind certain first mortgages. That is a file-by-file question.
For a closer look at this exact choice, Lendmire’s piece Second-Lien HELOC vs Cash-Out Refinance for a Low Fixed Mortgage walks through it in more detail.
What Decides the Outcome
Four things drive the answer on most files:
1. Size of the draw against your equity. A large draw leaves little room for a second lien behind the first.
2. Combined leverage. The lender adds the first loan and the second together and tests the total against value.
3. Your ability to carry both payments. A second lien adds to the monthly load. A cash-out restructures one payment on a larger balance.
4. Occupancy. A primary residence carries the highest leverage. Second homes and investment property sit lower, at 75% on a cash-out.
Credit and ratios matter too. Conventional wholesale programs start at a 620 decision score, and the automated finding governs most files with a total ratio ceiling of 50%. Some lenders set a higher floor on second liens.
When Neither Fits
Sometimes the answer is neither. If you do not need cash, a refinance or doing nothing may serve you better. A rate-and-term refinance pays off the existing first mortgage and closing costs with only incidental cash back. It reaches 95% LTV on a one-unit principal residence. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
If your existing loan is FHA or VA, the streamline products are built for existing government loans, not for cash. The FHA Streamline and VA IRRRL are no-cash tools. HUD describes the streamline as a refinance of an existing FHA mortgage with limited credit documentation. VA describes the IRRRL as a VA-to-VA loan. A homeowner with a government loan who wants cash needs the program’s own cash-out refinance, or a second lien where the first loan’s rules allow one.
A word on cancellation. On a principal residence, both a refinance and a home equity loan carry a three-business-day right to cancel. Saturdays count. Sundays and legal public holidays do not. It does not apply to a vacation or second home, per the FTC.
A Simple Way to Decide
Work through these questions in order:
1. Is the first mortgage worth protecting? If yes, lean toward the second lien.
2. Is the draw large relative to your equity? If yes, lean toward the cash-out.
3. Can you carry two payments, including one that may move? If no, lean toward the cash-out.
4. Will you hold the loan long enough to recover a full closing? If no, lean toward the second lien.
5. Do you need the cash at all? If no, consider neither.
One more point: tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Key Terms Defined
Second lien: A loan secured by your home that sits behind your first mortgage in repayment order.
Cash-out refinance: A new, larger first mortgage that pays off the old one and gives you the difference in cash.
HELOC: A revolving line of credit secured by your home that you draw on and repay over time.
Combined LTV (CLTV): Your first mortgage plus any second lien, divided by the home’s value.
Seasoning: The minimum time a loan must be in place, or a borrower on title, before a cash-out is allowed.
Right of rescission: The three-business-day window to cancel certain loans on a primary residence.
A Balanced Verdict
Neither option wins on its own. The second lien suits the homeowner who values the first loan and needs a measured amount of cash. The cash-out suits the homeowner who needs a large sum or whose first loan has no special value. Run the choice against your equity, your ability to carry the payments, and how long you will keep the loan.

Frequently Asked Questions
Does a cash-out refinance reprice my whole balance?
Yes. The new loan replaces the old one, so the full balance moves to the new terms, not only the cash you take out. That is why a lock-in homeowner often looks at a second lien first. The cash-out also needs a full new closing and appraisal.
Is a second lien always cheaper than a cash-out refinance?
No. The CFPB notes that second liens often carry higher interest rates than first mortgages. The better choice depends on the draw size, closing costs, the terms of your first loan, and how long you keep the new loan.
Does an unused HELOC count against me?
It can, because lenders count the full credit limit when they test combined leverage, not just the drawn balance. A line you never use can still reduce how much you can borrow elsewhere.
Can I use these options on a second home?
Leverage is lower. A conventional cash-out on a second home or investment property sits at 75% LTV, against 80% on a one-unit primary residence. Occupancy decides which cap applies. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Can I take cash out of an FHA or VA loan with a streamline?
Not directly. The FHA Streamline and VA IRRRL are no-cash tools for existing government loans. Cash needs the program’s own cash-out refinance or a second lien, subject to the first loan’s rules.
