The Quick Read: With little equity, equity decides the question before anything else does. A conventional cash-out refinance is usually the harder door to open, because it stops at 80% of your home’s value on a one-unit primary residence. A second mortgage adds a separate loan behind your first, but it has its own combined-leverage test and each lender’s own limits. For many low-equity homeowners, the honest answer is a third option: a rate-and-term refinance that restructures the loan you have without pulling cash out.
Here is who each option is really for. A cash-out refinance fits someone with real equity who wants one loan and one payment. A second mortgage fits someone who wants to keep the first loan as is and still has room under the combined ceiling. If you have thin equity, you may qualify for neither. Both are subject to lender guidelines and full file review, and nothing here is a commitment to lend.
Cash-out refinance estimate
The starting figures are an example value with a balance and a cash request in proportion. Replace them with yours.
Editable benchmark: 7.32% as of October 22, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a cash-out refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $193,000 current balance, the agency cap on a one-unit principal residence, a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a cash-out refinance quote; a cash-out loan is priced by the lender at lock. The cash available is the loan the program cap allows less the balances paid off, before closing costs, which are not included. The HELOC line is the program’s combined loan-to-value ceiling applied to the same value and balance. Taxes and insurance are editable estimates. Licensed in sixteen states for consumer mortgages.
Side-by-Side
The table compares the two products on the features that decide eligibility. Figures come from the programs Lendmire arranges through wholesale lenders, plus agency rules where noted.
| Factor | Cash-Out Refinance | Second Mortgage (Home Equity Loan or HELOC) |
|---|---|---|
| What happens to your first loan | Paid off and replaced | Stays in place |
| Number of payments | One | Two |
| Leverage ceiling (one-unit primary home) | 80% LTV conventional | Combined LTV test, plus lender limits |
| Leverage ceiling (2–4 units) | 75% LTV | Combined LTV test, plus lender limits |
| Mortgage insurance | Generally none at 80% or below | Depends on the lender and product |
| Credit floor | Starts at a 620 decision score on wholesale conventional | Set by each lender |
| Seasoning | First loan 12+ months old; 6 months on title | Set by each lender |
| Documentation | Full income, asset and credit file | Varies by lender |
Two details matter for low-equity borrowers. First, a HELOC counts at its full credit line when a lender measures combined leverage, whether or not you have drawn on it. Fannie Mae’s Selling Guide says so directly. An unused line still eats your equity on paper.
Second, the seasoning rules trip up recent buyers. The loan being paid off must be at least 12 months old, and you must have been on title for 6 months, with exceptions for delayed financing, inheritance and legal awards. Texas adds its own wrinkle, because the state constitution caps a homestead cash-out at the agency figure. Everything here is subject to lender guidelines.
What “Little Equity” Actually Does to Each Option
Equity is your home’s value minus everything you owe against it. Lenders turn that into a percentage. Loan-to-value (LTV) is your first mortgage divided by the home’s value. Combined loan-to-value (CLTV) adds every other lien on top.
Both tests divide by the lesser of the sales price or the appraised value. So the appraisal drives the outcome. A low appraisal can shrink your options overnight.
Picture a homeowner who bought with about 5% down a few years ago and has paid the balance down modestly. Her LTV is likely still in the 90s. A conventional cash-out refinance caps at 80%, so there is a gap she cannot cross. The Fannie Mae Eligibility Matrix lists that same 80% maximum for a one-unit primary residence and 75% for two to four units. Limited cash-out refinances on a primary residence run far higher, but they do not hand you meaningful cash. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
That is the core low-equity point. A cash-out refinance leaves you with roughly 20% equity at the ceiling. A second mortgage has no single published floor, but the combined balance still has to fit under whatever the lender allows.
When a Cash-Out Refinance Is the Better Fit
A cash-out refinance wins when your equity fits under the agency ceiling for your property type and you want simplicity. It is one new first mortgage that pays off the old one and hands you the difference. Every figure here varies by lender and program. For a deeper look at the home-loan side, see Lendmire’s cash-out refinance programs page.
It tends to fit when:
- You want one payment instead of two.
- You want to reset or change the term on the whole balance.
- Your equity clears the ceiling after the appraisal, with some cushion.
- You meet the seasoning rules: the loan being paid off is at least 12 months old, and you have been on title for 6 months, with exceptions for delayed financing, inheritance and legal awards.
- You live in the home. Freddie Mac’s cash-out section requires borrowers to occupy a primary residence on this loan type. A second home carries a 75% ceiling on conventional cash-out.
The tradeoff is real. A cash-out refinance re-prices your whole balance, not just the new money. If your current first loan has terms you like, replacing it just to pull cash is a bigger move than adding a second lien. Mortgage insurance also enters the picture above 80% LTV on other refinance types. It can be cancelled on request at 80% of original value with good payment history, no subordinate liens and no decline in value. It must end automatically at 78%.
One more catch. Freddie Mac treats a loan placed on a home you own free and clear as cash-out. And paying off a second lien that was not used to buy the home can flip a rate-and-term loan into cash-out. Check the wording on the Fannie Mae limited cash-out page before you assume your HELOC can ride along.
When a Second Mortgage Is the Better Fit
A second mortgage wins when your first loan is worth keeping and you only need a modest amount of cash. You leave the first mortgage untouched. You add a new loan behind it. The CFPB treats both a home equity loan and a HELOC as second mortgages when you already have a first.
It tends to fit when:
- Your first loan has terms you would not want to give up.
- You need a smaller sum, or want flexible access over time through a line of credit.
- Your equity falls short of the cash-out ceiling, but a lender is willing to lend within its own combined limit.
- You can live with two payments.
A second mortgage sits behind the first, so the lender takes more risk, and its terms usually reflect that. If a second lien stays in place during a later refinance, the holder must agree in writing to stay behind the new first loan. That is called a resubordination agreement. Fannie Mae’s subordinate financing rules require it to be recorded. This is where “refinance and keep the second” can stall.
Also, a lender that finds a new or increased lien after the underwriting decision must re-underwrite the loan. Don’t open a HELOC in the middle of a refinance. It will surface.
Finally, the full line counts against your equity. A zero balance on a large HELOC still uses up your combined-leverage room.
The Third Option Many Low-Equity Homeowners Miss
If cash is not the real goal, a rate-and-term refinance (also called a limited cash-out refinance) may be the better tool. It is not a cash-out loan. It replaces your first mortgage, covers closing costs and any purchase-money second lien, and allows only incidental cash back.
Across the wholesale programs Lendmire places files with, the leverage limit on a one-unit primary residence sits far above the cash-out ceiling. The exact figure depends on whether the existing loan is agency-owned and which first-time-buyer program applies. Mortgage insurance applies above 80% LTV. Freddie Mac’s product page says a no cash-out refinance can consolidate higher-cost seconds into one loan and roll in closing costs, as explained on its No Cash-Out Refinance page. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Government loans have streamlines that need little or no equity:
- FHA Streamline: for an existing FHA loan that is current. It must show a net tangible benefit. Per HUD, cash back above $500 is not allowed, and closing costs cannot be added to the new loan. No appraisal is required, and credit review is limited.
- VA IRRRL: for an existing VA loan. It carries a 0.5% funding fee unless you are exempt, needs no VA appraisal and requires a net tangible benefit. Seasoning is the later of 210 days and 6 payments. It cannot pay off other loans.
Neither one is a way to get cash. They are ways to restructure when your equity is thin. FHA rate-and-term with an appraisal reaches 97.75%.
If your balance is above the conforming limit, jumbo lanes take over. They start at a 660 decision score, reach 90% leverage and loans up to $5,000,000, with a 50% ratio ceiling on the fixed lanes. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Risks That Grow When Equity Is Thin
Either product puts your home on the line. The CFPB’s home equity guide says you are taking a loan you must repay, with your home as collateral, and missed payments risk foreclosure. It also warns against borrowing more than you need. A default on a second lien can threaten the home even if the first mortgage is current.
Thin equity adds specific problems:
- Value drops. A small decline can leave you owing more than the home is worth. That makes selling or refinancing later difficult.
- Stacked leverage. A second mortgage on top of a high-LTV first loan leaves almost no cushion.
- Credit and ratios. Wholesale conventional programs start at a 620 decision score, with a 50% total ratio ceiling on most automated findings. Manually underwritten loans run 36% or 45%. Credit events carry agency waiting periods: four years from a chapter 7 discharge, seven from a foreclosure, four from a short sale or deed-in-lieu. Shorter periods may apply with documented extenuating circumstances.
Some borrowers reach for cash to pay off credit cards. That can make sense. It can also convert unsecured debt into debt secured by your house.
If Neither Option Fits Right Now
Many homeowners with thin equity have better moves than forcing a loan.
- Wait and pay down. Regular payments build equity, and gains in value help too. Each point of LTV you shed opens options.
- Borrow less. A smaller second mortgage may fit where a large cash-out cannot.
- Fix the first loan. A rate-and-term or streamline refinance may improve your situation without touching equity.
- Check your appraisal assumptions. The lesser of price or appraised value governs. Know your likely number before you apply.
- Look at non-equity options. Savings, a smaller project scope or phasing the work can avoid borrowing against the home at all.
Another path is to skip the new debt and share the upside instead. Lendmire’s piece Shared Equity vs Cash-Out Refinance for a Homeowner Who Plans to Stay walks through that tradeoff.

Frequently Asked Questions
Can I do a cash-out refinance with less than 20% equity?
Usually not on a standard conventional loan, because the ceiling is 80% LTV on a one-unit primary residence. Two- to four-unit homes and second homes sit lower, at 75%. If your equity is thinner than that, a rate-and-term refinance or a smaller second mortgage is often the realistic route, subject to lender guidelines.
Is a HELOC the same as a second mortgage?
Yes, when you already have a first mortgage. The CFPB treats both home equity loans and HELOCs as second mortgages. The difference is structure: one is a lump sum, the other a credit line.
Does an unused HELOC count against my equity?
Yes. Lenders count the full credit line when measuring combined leverage, drawn or not. Closing an unused line before applying can change the math for a refinance.
Can I refinance and keep my second mortgage?
Sometimes. The second-lien holder must agree to a recorded resubordination behind the new first loan. If the lender will not, the plan can stall, so confirm early.
Can a streamline refinance give me cash?
No. FHA caps cash back at $500, and a VA IRRRL cannot pay off other loans. Both are for restructuring an existing government loan, not pulling equity.
The Balanced Verdict
Choose a cash-out refinance if your equity clears the ceiling, you want one payment, and re-pricing the whole balance makes sense. Choose a second mortgage if your first loan is worth keeping and a lender will lend within its own combined limit. Choose neither if the cushion is thin and the cash is not urgent. A rate-and-term refinance or a streamline may solve the real problem.
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.
