The Quick Read: A cash-out refinance fits when you want one new first mortgage, a single payment, and enough equity left under the ceiling to cover the payoff, the closing costs, and the cash you need. A HELOC fits when your current first mortgage is worth keeping and you need a smaller or staged amount. The loan-to-value cap squeezes a refinance hardest because the new loan has to pay off the whole old balance first. Both options put the home at risk if you can’t repay, and every figure here is subject to lender guidelines and full file review.
Side-by-Side
The two products answer the LTV cap in different ways. A refinance replaces the first lien, so the cap applies to the whole new balance. A HELOC sits behind the first lien, so the lender’s own combined limit applies to the first mortgage plus the new line.

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.
| Factor | Cash-Out Refinance | HELOC |
|---|---|---|
| Lien position | New first mortgage replaces the old one | Second lien behind your current first |
| Leverage cap (conventional) | 80% on a one-unit primary home | Set by each HELOC lender |
| Other occupancies | 75% on 2-4 units, second homes, investment | Varies by lender |
| Credit floor | 620 decision score on wholesale conventional | Varies by lender |
| Mortgage insurance | None at 80% or below; wholesale no-MI lane is the exception | Generally none |
| Documentation | Full file review, appraisal | Varies by lender; value still needs support |
| Existing first mortgage | Paid off and replaced | Left in place |
| Payments after closing | One mortgage payment | First mortgage plus a second payment |
Two notes on that table. The HELOC column says “varies by lender” on purpose. Agency cash-out caps and a bank’s HELOC limits are two separate rule sets, so a number from one doesn’t carry over to the other. And the 80% figure is the conventional cap; confirm it against the current Fannie Mae Selling Guide and its Eligibility Matrix, which is where the ratios live.
How the Cap Sets Your Cash
The cap limits the size of the new first mortgage, and that is the whole problem. Take the home’s appraised value and multiply by the maximum LTV. That’s the largest new loan. Then subtract what the loan has to do first: pay off the old first mortgage, pay off any second lien that has to go, and cover closing costs. What’s left is your cash.
Run it in percentages. Say a home appraises with an existing first mortgage sitting at 60% of value. At an 80% cap, the new loan can reach 80%. That leaves 20 percent of value, minus closing costs, as cash. If the existing balance is at 70%, only half that room remains before costs. If it’s near the cap, almost nothing is left. Same cap, very different cash.
Three things shrink the number:
1. A low appraisal. The appraisal is the denominator. A lower value cuts the maximum loan and the cash with it.
2. Closing costs rolled in. Costs financed into the loan count against the ceiling.
3. A second lien or HELOC that has to be paid off. It comes out of the same pot.
On the loan-size side, this is where a lot of files stall. The borrower sizes the cash need on the zestimate, the appraisal comes in light, and the refinance shrinks below what the project needed. Build the plan on a conservative value, not the best-case one.
When a Cash-Out Refinance Is the Better Fit
A cash-out refinance wins when you have real equity and the first mortgage isn’t something you’re protecting. It also wins when you need a large lump sum, because a HELOC lender’s limit can fall short of the amount.
It tends to fit when:
- Your equity sits comfortably below the cap, so the payoff, costs, and the cash you want all fit under 80% on a one-unit primary home.
- You prefer one mortgage payment to two.
- You want a fixed lump sum for a defined purpose, such as a major renovation or consolidating debt, with the structure known up front.
- Your current first mortgage terms aren’t worth keeping, so replacing the whole balance costs you nothing you’d miss.
- You’re paying off a second lien anyway and want to fold everything into one loan.
Seasoning matters. Across the wholesale programs Lendmire places files with, the first mortgage being paid off must be at least 12 months old, and a borrower generally needs to have been on title for 6 months, with exceptions for delayed financing, inheritance, and legal awards. Files that skip the seasoning check get sent back. For details on how these programs are structured, see Lendmire’s cash-out refinance programs page.
One wholesale lane is worth knowing about. On a thirty-year fixed, primary residence, conforming balance, a cash-out can reach 89.99% LTV with no mortgage insurance at a 680 score and a 50% ratio, with its own six months of seasoning. It’s the exception to the usual rule that mortgage insurance applies above 80%. It isn’t written in Texas, where a homestead cash-out under Section 50(a)(6) is capped at 80% of the home’s value by the state constitution. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Occupancy sets the leverage. A second home or investment property drops the cap to 75%, as does a two- to four-unit primary home. That’s all this article says about those cases.
When a HELOC Is the Better Fit
A HELOC wins when the first mortgage is the asset. If the loan you have carries terms you’d lose by refinancing, leaving it alone and borrowing against the equity behind it protects the part that’s working. The CFPB notes that a cash-out refinance may be more or less expensive than a HELOC, depending on the terms, so neither is automatically cheaper.
It tends to fit when:
- You need a smaller amount, or you need it in stages over time rather than all at once.
- Your first mortgage is one you want to keep.
- Closing costs on a full refinance would eat too much of a modest cash need. A refinance often carries full mortgage closing costs; HELOC costs vary by lender.
- The cap leaves too little cash after payoff, but the lender’s combined limit leaves room for a line.
The catch is the combined limit. A HELOC lender looks at the first mortgage plus the new line against value. Freddie Mac’s guide defines three ratios: LTV, total LTV, and HELOC total LTV. The HELOC ratio is built around the credit limit, not the drawn balance. So an undrawn line still counts when a later refinance is reviewed.
That brings up the trap that catches borrowers who take a HELOC first. If you later want to refinance the first mortgage, the HELOC lender may have to agree to stay in second position, and it can refuse. The CFPB says you may need that lender’s approval, and if it declines, you may need to pay the HELOC off. A bigger new first mortgage also thins the HELOC lender’s cushion, which is why the refusal happens.
When the Cap Leaves Too Little Cash
If the math lands near zero, stop and pick one of four paths. Don’t force a loan that doesn’t clear.
1. Borrow less. Resize the need to what fits under the cap after payoff and costs.
2. Stage the draws. A HELOC lets you take money as you need it instead of sizing the whole amount on day one.
3. Wait for equity. Principal paydown and value changes move the ratio. Waiting can reopen the refinance.
4. Pay off a second lien in the right order. If a HELOC or second mortgage is on the home, it counts against the same ceiling. Whether paying it off counts as a limited cash-out can depend on how the second lien was used.
Don’t borrow right up to the ceiling if you can avoid it. A small drop in value can leave you with a balance close to or above what the home is worth, and a variable-rate line can raise your payment. Leave room.
Government Loans Work Differently
The caps above are conventional. Government loans follow their own agency rules, and the ceilings aren’t the same.
For FHA, HUD sets the cash-out limit at 80% of adjusted value for case numbers assigned on or after September 1, 2019, and it counts all liens. Before that date the limit was 85%, which is why older advice quoting 85% is stale. For VA, the loan amount may not exceed 100% of the home’s reasonable value on cash-outs taken on or after February 15, 2019. Some lenders add a lower cap of their own, but that’s a lender overlay, not a VA rule.
Don’t confuse these with the FHA Streamline or the VA IRRRL. Both are no-cash-out products for borrowers who already hold an FHA or VA loan, so they don’t help if you need equity.
Key Terms Defined
LTV (loan-to-value): The loan amount divided by the home’s appraised value.
CLTV (combined loan-to-value): All liens on the home added together, divided by the appraised value.
HELOC: A revolving line of credit secured by your home, usually sitting behind the first mortgage.
Subordination: An agreement by a lien holder to stay in second position when the first mortgage is replaced.
Seasoning: The minimum time you’ve held the loan or the title before a cash-out is allowed.
Limited cash-out: A refinance that pays off the old loan and costs with only incidental cash back.
A Quick Decision Rule
| Your situation | Usually the better fit |
|---|---|
| Large lump sum, equity well under the cap | Cash-out refinance |
| First mortgage terms worth keeping | HELOC |
| Small or staged need | HELOC |
| Want one payment, willing to replace the loan | Cash-out refinance |
| Cap leaves almost no cash | Borrow less, stage, or wait |
The honest verdict: the cap decides more than preference does. If the numbers fit under the ceiling after payoff and costs, a cash-out refinance gives you one loan and one payment. If they don’t, or if your first mortgage is worth keeping, a HELOC can reach equity the refinance can’t.
Frequently Asked Questions
Does an undrawn HELOC count toward the LTV limit?
Often yes. Freddie Mac’s HELOC total LTV ratio is built around the credit limit, drawn or not. A line you never touched can still reduce the amount a later refinance can reach, so ask how any open line will be counted before you apply.
Can I keep my HELOC if I do a cash-out refinance?
Only if the HELOC lender agrees to stay in second position. It can say no, since a larger first mortgage thins its cushion. If it refuses, the line may need to be paid off, and that payoff comes out of your available cash.
Is a cash-out refinance cheaper than a HELOC?
It depends on the terms. A refinance often carries full mortgage closing costs, while HELOC costs vary by lender. Neither is automatically cheaper, so compare the actual Loan Estimates and the cost of keeping versus replacing your first mortgage.
How much equity do I have to keep?
On a conventional cash-out for a one-unit primary home, the cap is 80%, so at least 20% equity stays in the home. FHA is also 80%. VA is 100% of reasonable value, though some lenders set a lower limit of their own. Occupancy and unit count can lower the conventional cap to 75%.
What if the appraisal comes in low?
The maximum loan shrinks with the value, and so does your cash. Your options are the ones above: borrow less, stage the draws, or wait. Ask the lender about an appraisal reconsideration with recent nearby sales if you think the value missed.
