The Quick Read: The two options draw on very different pools of money, and each puts something different on the line. A cash-out refinance borrows against your home’s equity and puts the house at risk. A 401(k) loan borrows from your own retirement balance and puts that nest egg at risk. The first suits people with solid equity and steady credit who want a long repayment period. The second suits people whose plan allows loans, who need a modest amount, and whose job feels secure.
If your purchase is large, the 401(k) loan will probably run out of room first, because the federal ceiling is far below what many homeowners can reach through equity. If your purchase is modest and your job is stable, borrowing from yourself can avoid a new mortgage entirely. Neither one is cheap in the way people hope. One costs you closing costs and a new loan on your home. The other costs you years of market growth on money that leaves your account. The right pick depends on how much you need, how much equity you hold, and how safe your paycheck is.
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: 7.18% as of November 5, 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.
Key takeaways
- A cash-out refinance replaces your current mortgage with a larger one and hands you the difference in cash.
- A 401(k) loan lets you borrow from your own vested balance, up to a federal cap, if your plan offers loans.
- Conventional cash-outs on a one-unit primary residence have a lower LTV ceiling than a purchase loan, and LTV is loan-to-value, meaning the loan as a percentage of the home’s appraised value.
- A 401(k) loan can become a tax problem if you leave your job and cannot repay it.
- The better choice depends on the purchase size, your job security and the terms on your current mortgage.
Side-by-Side
A table makes the tradeoffs easier to see. Program figures reflect typical wholesale conventional guidelines and are subject to lender guidelines and full file review. They are not a commitment to lend.
| Factor | Cash-Out Refinance | 401(k) Loan |
|---|---|---|
| What you borrow against | Home equity | Your vested plan balance |
| Leverage or limit | 80% LTV on a one-unit primary home | Up to 50% of vested balance, max $50,000 |
| Credit floor | 620 decision score and up, conventional | Set by the plan, often no credit review |
| Mortgage insurance | None at 80% LTV; no-MI lane to 89.99% | Not applicable |
| Occupancy | Primary, second home or investment | Not tied to any property |
| Documentation | Income, assets, statements, appraisal | Plan loan form from administrator |
| Repayment length | New mortgage term | Typically five years |
| What is at risk | Your home | Your retirement savings |
Two notes on that table. First, the 401(k) limits come from the IRS 401(k) resource guide for plan participants, which also says plans are not required to offer loans at all. Second, occupancy changes the cash-out leverage. The 80% figure applies to a one-unit primary residence, while two- to four-unit homes, second homes and investment properties generally top out at 75%.
How a Cash-Out Refinance Works
A cash-out refinance pays off your current mortgage with a new, larger one and gives you the extra amount as cash. You can spend it on anything. That freedom is the main appeal.
The lender checks a few things. It looks at your equity, because the new loan has to fit under the maximum LTV. It orders an appraisal, so the home’s value sets your ceiling. It reviews your credit, your income and your total debt ratio. Across the wholesale programs Lendmire places files with, conventional loans start at a 620 decision score, and the automated underwriting finding governs most files, with a total debt ratio ceiling of 50%.
Timing rules matter too. The mortgage being paid off must generally be at least 12 months old, counted from note date to note date. You also need to have been on title for six months, with exceptions for delayed financing, inheritance and legal awards. Freddie Mac’s Guide section on cash-out refinances sets out the six-month ownership test.
Reserves can come into play as well. Reserves are cash or assets you keep after closing. Agency matrices apply them to some cash-out files, especially when your debt ratio runs high. Fannie Mae’s Eligibility Matrix shows how maximum leverage changes by transaction type and occupancy. A cash-out sits well below the purchase limits.
One more wrinkle: the new loan replaces your old one. Your old mortgage’s terms go away, and the new terms apply to the whole balance. That matters if you have a loan you like. Lendmire’s cash-out refinance programs page lays out the program options and the equity each one reaches.
How a 401(k) Loan Works
A 401(k) loan is not a withdrawal. You borrow from your own vested balance and repay yourself, typically through payroll deduction. Your plan document decides whether loans are allowed at all. Many plans offer them, but the IRS says plans are not required to.
If your plan permits loans, the federal limit is generally the lesser of 50% of your vested balance or $50,000. Earlier loans reduce that cap. Repayment is due within five years in most cases, with level payments made at least quarterly. A loan used to buy your main home can run longer.
There is no appraisal and no mortgage closing. Some plans charge small administrative fees. Many skip the credit check altogether because you are borrowing your own money.
Here is where it gets tricky. If the loan breaks the rules, it can turn into a taxable “deemed distribution.” The IRS explains this on its page about plan loan failures and deemed distributions. Tax treatment can depend on your situation. Skip guessing and ask your plan administrator and a tax adviser before you borrow.
When a Cash-Out Refinance Is the Better Fit
A cash-out refinance is the better fit when the purchase is big and you hold meaningful equity. Equity is the part of the home’s value you own outright. At 80% LTV on a one-unit primary home, the reachable cash can far exceed what a 401(k) loan allows. The IRS cap is a hard stop, while equity has no matching ceiling. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Picture a homeowner with a large renovation or a major purchase planned. Say the project costs more than half of the vested 401(k) balance. A plan loan cannot cover it, and borrowing even part of it would drain the account. A cash-out refinance could cover the full amount if the home carries enough equity.
It also fits people who want a longer repayment period. A mortgage spreads repayment over many years. The Consumer Financial Protection Bureau’s guide to using home equity notes that a cash-out may lengthen the time to pay off your mortgage, and that the monthly payment can rise because the loan is larger. Both are real tradeoffs to weigh.
Job security is another reason. A cash-out refinance does not depend on your employer. If you change jobs, nothing about the loan changes. That is a quiet advantage over a 401(k) loan.
A few more situations favor the refinance:
- Your retirement account is small or your plan does not allow loans. The option may not exist for you.
- You want to leave retirement savings invested. Money that stays in the account keeps compounding.
- Your current mortgage terms are no longer a bargain. If you are not giving up a loan you love, replacing it costs you less.
- Your credit and debt ratio are solid. Credit scores and a total debt ratio near or under the 50% ceiling support the file.
The wholesale no-mortgage-insurance lane deserves a mention. It applies to a thirty-year fixed loan on a primary residence at a conforming balance, with its own six months of seasoning. Conventional cash-outs otherwise stop at 80% on a one-unit primary home, so this lane is the exception for people who need more reach. In Texas, a cash-out on a homestead is capped at 80% of the home’s value by the state constitution, and that wholesale lane is not written there. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
The downside is plain. Your home becomes collateral for a bigger loan. Closing costs apply to the whole new balance. And you have to qualify.

When a 401(k) Loan Is the Better Fit
A 401(k) loan is the better fit when the amount is modest, your plan allows it, and your job is stable. You skip the appraisal, the new mortgage and the closing costs. You also leave your current mortgage untouched, which matters if its terms are valuable.
Consider a borrower who needs a moderate sum for a vehicle or a short-term project. The amount sits comfortably under half of the vested balance. The paycheck is steady, and the borrower plans to stay at the same employer. A plan loan can be simple here.
It also helps if your credit or debt ratio would complicate a mortgage file. A conventional cash-out starts at a 620 decision score, and a debt ratio above the program ceiling can end the application. A plan loan generally does not hinge on those tests. Fannie Mae’s rule on monthly debt obligations treats a loan secured by a 401(k) as a contingent liability. A lender need not count the payment in your monthly debts if it receives the loan document showing the asset as collateral. A lender may still apply its own rules, though.
That helps qualifying, but it does not change your real budget. The repayments still come out of your paycheck. A lender’s math and your household’s math are different things.
Here is the part people underestimate: job loss. A plan can require early repayment when you leave. An unpaid balance may become a taxable distribution. In short, the loan is safest when you expect to stay put.
Opportunity cost is the other hidden price. While the money is out of the account, it is not growing with the market. Some plans also limit new contributions or the employer match during repayment, so ask your administrator before you borrow. The closer you are to retirement, the more that missed growth on a large share of the balance can matter, and past a certain point it can outweigh the burden of a longer mortgage. For a borrower near retirement, that tilts the choice toward the refinance. For a borrower with many working years ahead, the loan’s advantage of avoiding a new mortgage carries more weight.
Key Terms Defined
Cash-out refinance: a new mortgage that pays off your old one and gives you the leftover equity as cash.
LTV (loan-to-value): your loan balance divided by the home’s appraised value, shown as a percentage.
Vested balance: the part of your 401(k) that belongs to you, including the employer money you have earned the right to keep.
Deemed distribution: a plan loan that breaks the rules and is treated as taxable income.
Seasoning: the waiting period a lender wants between events, such as the age of the loan being paid off.
Mortgage insurance: coverage that protects the lender and applies to most conventional loans above 80% LTV, with the no-MI wholesale lane as the exception. It can be cancelled at 80% of the original value on request and ends automatically at 78%.
Worked Comparison: One Purchase, Two Routes
Run a purchase through both routes without dollars. Say you need cash equal to roughly a third of your home’s value. That is the kind of size that tests the two options.
On the refinance route, your current balance plus the new cash must fit under 80% LTV. If you owe 40% of the home’s value today, you could add about a third and land around 73%, inside the limit. If you already owe 65%, the same cash would take you past 80%, and the refinance would not reach that far. The appraisal decides. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
On the 401(k) route, the limit is the lesser of half your vested balance or the federal cap. If your balance is large, the cap still applies. If your balance is small, the 50% rule binds sooner. Either way, the amount you can borrow is fixed by the plan, not by the purchase.
Now compare what you give up. The refinance trades your old loan’s terms for new ones and adds closing costs on the whole balance. The plan loan trades market growth on the borrowed money for a short, fast-ending repayment schedule. Neither is free. The home is the collateral in a cash-out, and your retirement savings are the collateral, in effect, in a plan loan.
Checklist: How to Decide
Work through these in order.
1. Does your plan allow loans? If not, the decision is made.
2. How big is the purchase compared with the cap? If it exceeds the plan limit, the refinance is the practical route.
3. How much equity do you hold? If you cannot stay at or under 80% LTV after the cash-out (75% for second homes, investment properties and two- to four-unit homes), the refinance may not reach.
4. How secure is your job? If a layoff would be likely, a plan loan carries real extra risk.
5. What do your current mortgage terms look like? If you like them, keep them and consider the plan loan for smaller needs.
6. How long until you retire? The closer you are, the more lost growth hurts.
7. Could you combine the two? Some borrowers use a plan loan for a small piece and a refinance for the rest. Each has its own limits, so check both. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Common Mistakes to Avoid
- Assuming every plan offers loans. The IRS says plans do not have to.
- Assuming a 401(k) loan is always tax-free. It only stays tax-free if it meets the IRS limits and repayment rules.
- Treating the payroll deduction as free money. Repayments are real budget items even when a lender need not count them.
- Confusing a limited cash-out with a full cash-out. A limited cash-out, also called a rate-and-term refinance, allows only small amounts of cash back. Fannie Mae and Freddie Mac cap it at an incidental level, so it cannot fund a big purchase.
- Expecting streamline refinances to pull cash. The FHA Streamline and VA IRRRL work on existing government loans and do not pay out cash.
- Ignoring seasoning. A recent purchase or a young loan can delay a cash-out.
The Verdict
Choose the cash-out refinance if you need a large amount, hold healthy equity, and want to leave your retirement account alone. Choose the 401(k) loan if the amount is modest, your plan allows it, and you expect to stay with your employer for the full repayment period. The decision usually comes down to size and stability. Size favors the refinance. Stability favors the plan loan.
Neither choice is without risk. Cash-outs can put your house on the line, and plan loans can put your retirement on the line. If the purchase can wait, saving toward it is another option, though it is outside this comparison. If you are leaning toward the refinance, remember that every program figure here is subject to lender guidelines and full file review, and none of it is a commitment to lend.
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.
Frequently Asked Questions
Can I use both a cash-out refinance and a 401(k) loan for the same purchase?
Yes, in principle, because they are separate transactions. A lender may still ask about the plan loan when you apply for the mortgage. Fannie Mae’s rule lets lenders leave out the plan loan payment from your monthly debts if the loan document is provided, though a lender can apply its own standards.
What happens to a 401(k) loan if I lose my job?
The plan may require early repayment. An unpaid balance can become a taxable distribution. Ask your administrator what your plan does and talk to a tax professional.
Is a cash-out refinance the same as a HELOC?
No. A cash-out refinance replaces your first mortgage with a new, larger one. A HELOC is a separate line of credit on top of your existing loan. The CFPB treats them as different products, and which costs more depends on the terms of each.
Do I need to live in the home to do a cash-out refinance?
Not necessarily. A cash-out can be written on a primary residence, a second home or an investment property, and occupancy sets the leverage. The leverage ceiling is 80% for a one-unit primary home and 75% for the other property types.
How long do I have to own my home before a cash-out refinance?
The mortgage being paid off must generally be at least 12 months old, and a borrower needs to have been on title for six months. Exceptions exist for delayed financing, inheritance and legal awards. The wholesale no-MI lane has its own six months of seasoning.
