The Quick Read: No, not inside the FHA cash-out refinance itself. The 80% cap applies to your combined debt, so any second lien that stays on the home or is added at the same time uses up room instead of adding any. A separate home equity loan or line of credit opened later, after the FHA loan is in place, is a different contract with its own lender and its own limits, subject to lender guidelines and full file review.
Most people ask this question because the cap feels like a lid, and a second lien feels like a way to lift it. It isn’t. The cap measures every loan against the home’s value, not just the new first mortgage. This article walks through three situations people mean by “second lien,” how lenders count the total, and how to choose.
What the FHA Cash-Out Cap Actually Limits
The FHA cash-out refinance reaches 80% of the home’s value, on a home you have owned and occupied for 12 months before the case number. That is the program figure across the wholesale lenders Lendmire works with. Lendmire is a mortgage broker, not a lender, and every figure here is subject to lender guidelines.
The 80% is not a limit on one loan. HUD set it as a limit on loan-to-value and combined loan-to-value together. HUD Mortgagee Letter 2019-11 cut the cash-out maximum to 80% of the adjusted value, down from 85%. HUD said it wanted to limit risk to the FHA Insurance Fund from rising balances on cash-out loans.
Adjusted value is the appraised value, tweaked by HUD’s rules for the transaction. The appraisal is where everything starts. A higher or lower appraisal moves the cap, and the cap moves everything else.
One quirk: the 2019 change does not apply to Section 247 Hawaiian Homelands mortgages. If that’s not your situation, skip it.
Three Situations People Mean by “Second Lien”
The phrase covers three different things. Each one gets a different answer.
| Situation | Does the 80% cap apply? | Who decides |
|---|---|---|
| Existing second stays on the home | Yes, counts toward the total | Second lien holder and lender |
| New second taken with the cash-out | Yes, and many lenders won’t allow it | The first-mortgage lender’s rules |
| HELOC or home equity loan opened later | Not the cash-out cap | The second-lien lender |
Situation one: an existing second stays. You already have a home equity loan or HELOC. You refinance the first mortgage into an FHA cash-out and leave the second in place. The second counts toward the 80%. It uses up room.
Situation two: a new second at the same time. You try to pair the FHA cash-out with a brand-new second lien. Many lenders do not allow new subordinate financing on an FHA refinance. Others permit it only inside the combined limit. Either way, the cap still applies. That is lender policy, not a HUD ban, so the answer depends on who you apply with.
Situation three: a second lien later. You keep your FHA loan, or finish a cash-out, and months afterward you open a HELOC. The FHA cash-out cap does not govern that later loan. The limits come from the second lender: its combined-loan ceiling, its credit rules, and whether it will sit behind an FHA first mortgage at all.
Hold that third answer loosely. The cash-out cap governs the refinance transaction. Whether a later lien can exceed it is a question for the second lender, not for HUD’s cash-out rule.
How Lenders Count the Combined Total
Lenders add up three things and divide by the adjusted value: the new first mortgage (without the financed upfront premium), the balance of any closed-end second, and the full credit limit of any HELOC.
Read that last part twice. An unused HELOC still counts at its full limit. A line with nothing drawn on it can still eat room under the cap. Freezing it is not enough. Reducing the limit or closing the line is what frees the room.
Here is the arithmetic in percentages only. Say the cap is 80% of value. You keep a second lien equal to 10% of the home’s value. That leaves at most 70% of value for the new first mortgage. Your cash-out shrinks by exactly what the second lien takes.
Now run it the other way. Suppose you have a HELOC with a limit equal to 15% of value, and you’ve drawn almost none of it. Lenders still count the 15%. The new first mortgage gets at most 65% of value, and the cash you pull out shrinks with it. An investigation of a “cash-out” that nets little usually starts here.
Also remember what 80% does not mean. It does not mean 80% in your pocket. Cash is what remains after paying off the old mortgage, any liens being paid, and costs. Credit, income, and the new payment still have to work.
Keeping an Existing Second: Subordination Step by Step
Subordination means the second lien holder agrees to stay behind the new FHA first mortgage in line. Without that agreement, the new loan would not be the first lien.
1. Order the appraisal. The cap is measured against adjusted value, so you need the number early.
2. Ask your second lien holder. Find out whether it will subordinate and what it needs. It has no obligation to say yes.
3. Gather the paperwork. Lenders typically ask for the subordination agreement plus the second lien’s note and deed.
4. Run the combined math. New first plus the second (or the full HELOC limit) must sit at or under 80% of value.
5. Prove you can pay all of it. You qualify on the new first payment and the existing second payment together.
What can go wrong? The second lender says no. Or it agrees but takes its time while your appraisal ages. Or the combined math lands just over the line. Any of those can send you back to the drawing board.
For history, HUD Mortgagee Letter 2009-08 once covered re-subordination of existing seconds under an older 85% rule. It has been superseded. Today’s number is 80%.
The Payoff Trap
Some borrowers plan to roll a second lien into the new loan. That is allowed in concept. The second gets paid off, and its balance becomes part of the new first mortgage. The catch: the new first must still fit under the cap on its own.
So paying off the second does not create room. It moves the debt into the one loan that now carries the whole 80% limit. If the second was large, the leftover cash can be small or zero.
The type of refinance matters too. A streamline is a different animal from a cash-out. The FHA Streamline refinances an existing FHA loan with no appraisal and a net tangible benefit, and its proceeds are meant to cover the payoff and costs, not hand you cash. Changing the structure mid-file can change which program applies. Ask before you assume.
Adding a Second Lien After the FHA Loan Is in Place
This is the real route to “above the cap.” Not above it in the cash-out transaction, but outside it.
A home equity loan or HELOC opened later is a separate contract with a separate lender. As the CFPB explains, a second mortgage is called “second” because it gets paid second if the home is sold to cover debts. You make a separate monthly payment on top of your FHA payment.
FHA does not offer a home equity line of its own. A second lien behind an FHA first comes from another lender, and that lender has to accept the junior position. Many do not want it. If you can’t find one, that is the answer: no second lien.
What the second lender looks at:
- Its own combined-loan ceiling, set by its guidelines
- Your credit and your ability to pay both loans
- The home’s current value
- Whether the FHA servicer needs to be notified
None of that is the FHA cash-out cap. It’s a different test with a different decision-maker.
The risks are real. Home equity loans are usually repaid over a shorter period than a 30-year mortgage, so the payment can be larger. Two loans also mean two sets of closing costs. And falling behind on either one puts the home at risk.
FHA Cash-Out vs. a Later Second Lien
Neither is better in the abstract. They solve different problems.
| Factor | Later second lien | FHA cash-out |
|---|---|---|
| First mortgage | Stays as is | Replaced |
| Mortgage insurance | Existing FHA premium continues | New upfront and annual premium |
| Payments | Two | One |
| Key limit | Second lender’s rules | 80% of value, all liens |
| Upfront cost | Second loan’s costs | New first loan’s costs |
Think of it this way. If your current first mortgage is one you’d like to keep, a later second lien leaves it untouched. If you want one loan and one payment, a cash-out does that, but it replaces the first and resets the FHA premium: an upfront 1.75% of the base loan (financed), plus an annual premium that depends on term, loan amount and LTV.
Leaving FHA altogether is a third path. A conventional cash-out can drop FHA mortgage insurance, but it has its own credit and equity tests. The programs reach different amounts of equity, which is why comparing them side by side matters.
Who This Fits and Who It Doesn’t
An FHA cash-out fits you if you want one new loan, you’ve owned and lived in the home for 12 months, and your combined debt fits under 80% of value.
Keeping your loan and adding a second lien later fits you if you like your current first mortgage, you can find a second lender willing to sit behind it, and you can handle two payments.
Neither may fit if your existing second is large relative to the home’s value, or you can’t qualify on every payment at once. Credit and income count either way. FHA purchase loans start at a 580 decision score across the wholesale programs Lendmire works with, and ratios start at 31/43, reaching 40/50 with documented compensating factors. Refinance files are reviewed the same way, subject to lender guidelines.
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
Combined loan-to-value (CLTV): all loans secured by the home, added together, divided by the home’s value.
Adjusted value: the appraised value after HUD’s adjustments, used to measure the cap.
Subordination: a second lien holder’s written agreement to rank behind the new first mortgage.
Junior (second) lien: a loan secured by the home that is paid after the first mortgage if the home is sold.
Piggyback second: a second loan made at the same time as the main mortgage. Borrowers often use it to cover a small down payment, which is a purchase tool and not a cash-out one.
HELOC: a line of credit secured by the home that you can draw on repeatedly up to a limit.
Frequently Asked Questions
Can I get a HELOC on an FHA loan?
Yes, from a lender other than FHA, which does not offer its own. The second lender must accept the junior position, and many do not. Its own combined-loan limit and credit rules apply.
Does an unused HELOC count against the cash-out cap?
Yes. Lenders count the full credit limit, not the drawn balance. To free up room, you generally need to reduce the limit or close the line.
Can I keep my second lien when I refinance into an FHA cash-out?
Often, if the second lien holder agrees to subordinate and your combined debt stays within 80% of value. The second uses up part of that 80%, so your cash-out shrinks accordingly.
Does a piggyback second work with a cash-out refinance?
Not as a way past the cap. A piggyback is a purchase tool meant to cover a small down payment. On a cash-out refinance, a new second taken at the same time still counts toward the combined 80%, and many lenders won’t allow it.
Does the 85% figure still apply?
No. That was the pre-2019 cash-out limit. HUD cut it to 80% of adjusted value, which is the current rule.
