The Quick Read: The amount you can pull out depends on your home’s value, the leverage cap on each option, and what you still owe. A conventional cash-out refinance on a one-unit primary residence generally stops at 80% loan-to-value (LTV, the loan balance as a share of the home’s value), subject to lender guidelines. A second lien sits behind your first mortgage and is limited by combined leverage, so it can release real cash while your first loan stays in place. Which one releases more comes down to the size of your first balance, not just its terms.
The Honest Answer First
A cash-out refinance is for the homeowner who wants one new loan and does not mind giving up the current first mortgage. A second lien is for the homeowner whose first mortgage is worth protecting and who needs a smaller, targeted amount.
“Low first” can mean two things: a low interest rate, or a low balance. Both matter. A low rate is a reason to keep the loan. A low balance is why a second lien can release a lot of cash. The two often show up together, and that is when the comparison gets interesting.
Both options are secured by your home. Miss payments on either one and the home is at risk. Every figure here is subject to lender guidelines and full file review, and nothing here is a commitment to lend.
Side-by-Side
| Factor | Cash-Out Refinance | Second Lien (HELOC or Home Equity Loan) |
|---|---|---|
| What happens to your first | Paid off and replaced | Stays in place |
| Leverage ceiling | 80% on a one-unit primary residence | Combined limit set by the second-lien lender |
| Two- to four-unit or second home | 75% | Varies by lender |
| Credit floor | Wholesale conventional programs start at a 620 decision score | Set by the second-lien lender |
| Mortgage insurance | Required above 80% LTV; a wholesale lane to 89.99% has none | Generally not part of the structure |
| Occupancy | Primary residence gets the highest cap | Lender-specific |
| Documentation | Full file review, income and assets | Full file review, plus the first-lien terms |
| Seasoning | First mortgage at least 12 months old; 6 months on title | Lender-specific |
| Payments after closing | One | Two |
Read the table as a map, not a menu. Occupancy, seasoning, and the lender’s appetite for second liens can settle the question before preference does.
How Much Does Each Route Release?
The release math has the same skeleton for both. Start with the appraised value. Multiply by the maximum allowed ratio. Subtract what you owe on the loans that stay or get paid off. Subtract costs rolled into the loan. What is left is the cash.
The difference is what counts as “what you owe.” In a cash-out refinance, the new loan replaces the first mortgage. The cap applies to that single new loan. In a second lien, your first mortgage stays and counts in full. The cap applies to the combined total. Fannie Mae’s formula for combined leverage adds the original first-mortgage amount, the full HELOC line (drawn or not), and the unpaid balance of any closed-end second, then divides by the lesser of sales price or appraised value. An unused HELOC line still eats room. You can read the cash-out limits in the Fannie Mae Eligibility Matrix.
Here is the part the competing explainers skip. Run two homeowners through it, with no dollar figures needed.
Homeowner one has a small first balance. Say the first mortgage is a modest share of the home’s value, well under half. Under an 80% cap, there is a wide gap between what is owed and what is allowed. A cash-out refinance can release that gap, minus costs. A second lien can release much of the same gap while leaving the first loan untouched. For this homeowner, the two options may release similar amounts, and the choice turns on the first mortgage’s terms and the payment structure.
Homeowner two has a large first balance. Say the first mortgage already sits near 70% of value. The gap to an 80% cap is thin. A cash-out refinance releases only that thin slice. A second lien must fit inside whatever combined limit the lender allows, and many lenders set limits that leave very little room here. When the first balance is large, neither route releases much, and a second lien can be the harder one to find.
That is the real lesson of a low first mortgage. A small balance means lots of room. A low rate means a reason to keep the loan. If you have both, a second lien often fits.
When a Cash-Out Refinance Is the Better Fit
A cash-out refinance tends to fit when one or more of these is true:
- You need a large lump sum. One new loan can reach the full 80% ceiling, which may exceed what a second-lien lender will allow in combined terms.
- Your first mortgage is not worth protecting. If its terms are no better than what a new loan would offer, replacing it costs you little.
- You want one payment and one set of terms. Consolidating into a single loan simplifies the monthly picture.
- You already carry a second lien. Under Fannie Mae’s rules, paying off a second lien that was not used to buy the home makes the refinance a cash-out refinance, even if you take no extra cash. So you are in this lane regardless. The Fannie Mae Selling Guide says a cash-out refinance may pay off subordinate liens of any age.
- You want a fixed term for the full balance. A second lien can be adjustable, so a new first with a set term can feel steadier.
Lendmire’s cash-out refinance programs cover this lane. Across the wholesale programs placed through Lendmire, one wholesale lane reaches 89.99% LTV with no mortgage insurance, at a 680 score and a 50% ratio on a thirty-year fixed primary residence with a conforming balance. That lane carries its own six months of seasoning. It is not written on Texas homesteads, where state law caps cash-out at the agency figure. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Seasoning matters here. The first mortgage you are paying off generally must be at least 12 months old, measured from note date to note date. At least one borrower generally needs six months on title, with exceptions such as inheritance or a legal award. Freddie Mac’s Guide 4301.5 spells out the occupancy and title rules for cash-out.
When a Second Lien Is the Better Fit
A second lien tends to fit when:
- Your first mortgage has terms you do not want to lose. The new loan touches only the new money. Your existing loan keeps its balance, term, and structure.
- You need a smaller or flexible amount. A HELOC lets you draw as needed up to a maximum. A home equity loan pays out as a lump sum. The CFPB explains both.
- You have lots of room under the combined cap. This is the small-balance case above.
- You may repay soon. Costs on a second lien can be lighter than a full first-mortgage refinance. The CFPB notes some lenders waive some or all up-front costs. Treat that as a lender-by-lender question, not a given.
The tradeoffs are real. You carry two payments. A HELOC typically has a variable rate tied to an index plus a margin, so the payment can move. If you sell, a HELOC generally must be repaid in full right away. And the CFPB is plain on risk: a HELOC is secured by your home, so falling behind could cost you the house. See the CFPB’s page on what a HELOC is.
For a closer look at this exact choice, Lendmire’s piece Second-Lien HELOC vs Cash-Out Refi for Homeowners Keeping a Low First walks through the tradeoffs.
The Middle Path: Limited Cash-Out
There is a third lane, and people often confuse it with the first two. A refinance, also called limited cash-out, replaces your first mortgage but returns only incidental cash. It can reach 95% LTV on a one-unit primary residence, and up to 97% where the existing loan is agency-owned and the first-time-buyer program allows. Mortgage insurance applies above 80%.
The catch is what it can pay off. Only a second lien used to buy the property can roll into a limited cash-out loan. If your second came from a HELOC or a later equity loan, paying it off pushes the transaction into cash-out territory and the lower 80% cap. The Fannie Mae limited cash-out rules set these conditions. The 95.01% to 97% tier adds more: Fannie Mae must own the existing loan, the home must be a one-unit principal residence, all borrowers must occupy it, and the loan must run through Desktop Underwriter.
A second lien you leave in place during a refinance must be resubordinated, meaning its holder agrees to stay behind the new first. If you take more than the small permitted cash back, the loan is a cash-out refinance.
So the classification of your existing second lien can swing the cap from the 95–97% range down to 80%. Confirm that early.
What Can Block a Second Lien
Availability is the gating question nobody mentions. Before comparing, check these:
- Lender appetite. Many lenders skip second liens in some situations, so an option you want may simply not be offered.
- Title. If the home is held in an entity or trust, second-lien lenders may decline or require extra steps. Review how you hold title before you compare.
- Combined limits. Lenders must count all liens on the property when figuring combined leverage, including business loans such as SBA loans.
- Ability to repay. A larger total can fail on debt-to-income even when equity is plentiful. The automated finding governs most conventional files, with a total ratio ceiling of 50%.
- Occupancy. Primary residences get the highest cap. Two- to four-unit properties and second homes drop to 75% on a conventional cash-out. If your home is not your primary residence, occupancy decides the leverage, and the numbers change.
New or increased subordinate financing found before or at closing means the loan is re-underwritten. Do not take on a new HELOC mid-process.
Key Terms Defined
LTV (loan-to-value): The loan balance divided by the home’s value, shown as a percentage.
Combined LTV (CLTV or HCLTV): The total of all loans on the home, including the full HELOC line, divided by value.
Second lien: A loan secured by your home that sits behind your first mortgage in repayment priority. A home equity loan and a HELOC are both second liens.
Seasoning: The waiting period a lender wants before a refinance, such as a first mortgage being at least 12 months old.
Limited cash-out refinance: A refinance that replaces your first mortgage and returns only a small, capped amount of cash.
Resubordination: When an existing second lien’s holder agrees to stay behind a new first mortgage.
Costs, Risk, and What-Ifs
A full refinance brings a full set of first-mortgage closing costs. A second lien can bring lighter costs, though appraisal, application, and closing items can still apply. No neutral source offers a clean comparison, so ask each lender for their Loan Estimate and compare the full terms. A “no-cost” refinance, when you see one advertised, generally means the costs are built into the rate or the balance. They have not disappeared.
Think about your holding period. If you may sell or move soon, up-front costs get spread over fewer years, and a HELOC’s repay-on-sale feature may not matter. If you plan to stay a long time, the structure of the first mortgage matters more.
A few what-ifs worth considering:
- If the market shifts later, you can often refinance a first or a second separately, depending on the lender.
- If you want to keep the HELOC line open, remember that the full line counts toward combined leverage whether or not you draw on it.
- If you change your mind after signing, a refinance or home equity loan on your primary residence carries a right to cancel. You must cancel in writing within three business days. A phone call is not enough. See the CFPB’s rescission guidance.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
A Balanced Verdict
Neither option wins on its own. The right pick depends on three things: how much of the equity room you actually need, whether your first mortgage is worth keeping, and whether a second lien is even available to you.
If your first balance is small and you want to protect its terms, a second lien is a natural fit, and it can release a similar amount to a cash-out. If you need a large lump sum, already carry a non-purchase second lien, or have a first that is no better than a new one, a cash-out refinance is likely the cleaner route. If your first balance is already large, neither may release much, and the honest answer may be a smaller amount or waiting.

Frequently Asked Questions
Does paying off a second lien reduce my cash?
Yes, because the payoff comes out of the loan before any cash reaches you. Under Fannie Mae’s rules, paying off a second that was not used to buy the home also makes the refinance a cash-out refinance, so the 80% cap on a one-unit primary residence applies.
Does a cash-out always cost me my low first?
Yes, in the sense that a cash-out refinance pays off and replaces the first mortgage. You get a new balance, term, and payment structure. If keeping the old loan matters, a second lien leaves it in place, though it adds a second payment.
Does an unused HELOC line count against my leverage?
Yes. Fannie Mae counts the full HELOC line in combined leverage, whether you have drawn on it or not. An open but unused line still consumes room under the cap.
Can I get 95% or 97% leverage and still take cash?
Generally not. Those tiers belong to limited cash-out refinances, which return only a small capped amount. Taking meaningful cash makes the loan a cash-out refinance, where a one-unit primary residence is capped at 80% and a two- to four-unit property at 75%, subject to lender guidelines.
Do FHA and VA loans follow the same rules?
No. Each program has its own cap and seasoning. The FHA Streamline and VA IRRRL are no-cash-out options for existing government loans, so they do not release equity. VA cash-out has its own limits under VA rules, and lenders often set lower caps of their own.
If you are weighing a cash-out refinance against keeping the loan you have, Lendmire can help you compare the programs and the equity each one reaches.
