Home Equity Line of Credit (HELOC)

A home equity line of credit is a revolving credit plan secured by your home, with a limit you draw against as needed and a variable rate tied to a public index. Federal law gives it its own regime, and the most important thing in that regime is the gap between what a lender may do to your credit limit and what it may do to a balance you already owe.

Quick Summary

  • It is open-end credit secured by a dwelling, which is the trigger for the dedicated rules at 12 CFR 1026.40. A closed-end home equity loan falls outside them entirely.
  • A lender may freeze further draws or cut the limit on six broad grounds, headed by a significant decline in the home's value. It may accelerate the whole balance on only four narrow ones. The commentary measures that decline against your initial cushion rather than the home's value, so a ten percent fall in price can be enough.
  • That gap is why an undrawn line is not an emergency fund. The money can be withdrawn from availability at the moment you are most likely to want it.
  • The rate is not discretionary. It may move only with an index outside the creditor's control that is available to the general public.
  • Fees are constrained at the application stage. No nonrefundable fee may be imposed until three business days after you receive the disclosures and the required brochure.

Definition

A home equity line of credit is a revolving line of credit secured by a residence the borrower already owns. The lender approves a credit limit, usually set by applying a combined loan-to-value ceiling to a current appraisal and subtracting the existing mortgage balance. The borrower draws against that limit as needed, pays interest only on what is drawn, and repaid amounts generally become available to draw again.

Most plans run in two phases. During the draw period the borrower may take advances and the required payment is often interest only or a small percentage of the balance. When the draw period ends the repayment period begins, draws stop, and the outstanding balance amortizes over the remaining term, which can raise the required payment sharply. The guide to credit and debt covers that transition and what to check before taking a line.

It is frequently called a second mortgage, and while a line is commonly recorded in second position, that describes the lien rather than the product. A line can also be a first lien on a property with no mortgage. The defining feature is that it is open-end credit, which is what brings it inside Regulation Z's home equity plan rules: 12 CFR 1026.40 states that "the requirements of this section apply to open-end credit plans secured by the consumer's dwelling."

Advanced Explanation

The freeze and the call are different provisions, and the difference is the single most useful thing on this page. They sit a few lines apart in the same regulation and they are not symmetrical.

Under 12 CFR 1026.40(f)(2) a creditor may not "terminate a plan and demand repayment of the entire outstanding balance in advance of the original term" unless one of four things is true: there is fraud or material misrepresentation by the consumer in connection with the plan; the consumer fails to meet the repayment terms for any outstanding balance; any action or inaction by the consumer adversely affects the creditor's security for the plan or the creditor's rights in that security; or federal law on credit extended by a depository institution to its executive officers requires it and the initial agreement said so. That list is short and every item is about the borrower's own conduct.

Under 1026.40(f)(3)(vi) a creditor may instead "prohibit additional extensions of credit or reduce the credit limit" during any period in which one of six things is true, and the list is far broader: the value of the dwelling declines significantly below the appraised value used for the plan; the creditor reasonably believes the consumer will be unable to meet the repayment obligations because of a material change in the consumer's financial circumstances; the consumer is in default of any material obligation under the agreement; the creditor is precluded by government action from imposing the agreed rate; the priority of the creditor's security interest is adversely affected by government action such that the security is worth less than 120 percent of the credit line; or the creditor's regulatory agency notifies it that continued advances would be an unsafe and unsound practice. Separately, 1026.40(f)(3)(i) allows a creditor to reserve the same power in the initial agreement for any period during which the maximum rate under the plan is reached.

Two of those six grounds require nothing of the borrower at all. A fall in local house prices, and a lender's reasonable belief about a change in the borrower's finances, are enough to stop the line. This is not a theoretical risk: the Federal Reserve's own compliance publication noted during the 2008 downturn that "many financial institutions have begun freezing or reducing credit limits on existing home equity lines of credit." It is the reason an undrawn line is not a substitute for cash reserves. A line is most likely to be reduced during exactly the conditions that make a household want to draw on it: falling property values and a disrupted income. Money already drawn stays on its original terms in those circumstances, because a value decline is not on the acceleration list. Money not yet drawn can disappear.

How far values have to fall is quantified, and it is a much smaller drop than "significant decline" suggests. The official interpretation of 1026.40(f)(3)(vi)(A) sets a threshold that is measured not against the home's value but against the borrower's cushion: if the value declines such that "the initial difference between the credit limit and the available equity ... is reduced by fifty percent," that is a significant decline. The Bureau's own worked example makes the scale plain. On a house appraised at $100,000 with a $50,000 first mortgage and a $30,000 credit limit, the available equity is $50,000 and the difference between it and the credit limit is $20,000; half of that is $10,000, so a fall in value from $100,000 to $90,000 is enough. A ten percent decline can therefore support a freeze, and the more of the equity a line already commits, the smaller the fall required.

A freeze is temporary in law, which is the other half of the picture. The same commentary provides that a creditor may suspend or reduce "only while one of the designated circumstances exists," and that when the circumstance ceases to exist "credit privileges must be reinstated." The creditor must either monitor the condition itself and restore access as soon as reasonably possible, or shift that duty to the borrower by giving a notice that puts them on notice to request reinstatement, which it may require in writing. It may charge only bona fide and reasonable appraisal and credit report fees actually incurred in investigating whether the condition persists, and it may not charge a fee to reinstate a line once the condition has been found not to exist. One further limit sits in the same commentary: a reduction may not take the limit below the outstanding balance where doing so would require the borrower to make a higher payment.

The rate is variable but not discretionary, which is the opposite of what "variable" suggests to most readers. 1026.40(f)(1) permits a creditor to change the annual percentage rate only where the change "is based on an index that is not under the creditor's control" and that index "is available to the general public." So a HELOC rate moves with a published benchmark plus a margin fixed by the agreement, and a lender cannot simply reprice the plan because it has decided to. That is a genuine protection, and it is also why the payment on a drawn balance rises when short-term rates rise, whatever else is happening.

Three provisions about fees and disclosures that are concrete and easy to miss because they operate before the plan exists. 1026.40(b) requires the disclosures and the brochure to be given "at the time an application is provided to the consumer," and 1026.40(e) names the brochure: "What You Should Know About Home Equity Lines of Credit," or a suitable substitute. 1026.40(h) then provides that neither the creditor nor anyone else "may impose a nonrefundable fee in connection with an application until three business days after the consumer receives the disclosures and brochure," with mailed documents deemed received three business days after mailing. And 1026.40(g) requires a creditor to "refund all fees paid by the consumer to anyone in connection with an application" if any term required to be disclosed changes before the plan is opened, other than through movement in a variable-rate index, and the consumer therefore decides not to open the plan. Taken together, those give a genuine window to read the terms and a remedy if the terms move.

The right to rescind attaches to the plan rather than to each draw. Because a line is open-end credit, the applicable provision is 12 CFR 1026.15 rather than the closed-end rescission section. 1026.15(a)(1)(i) gives each consumer whose ownership interest is subject to the security interest a right to rescind the plan when it is opened, a security interest when it is added to secure an existing plan, and an increase in the credit limit. But (a)(1)(ii) provides that the consumer does not have the right to rescind each credit extension made under the plan where the extension is made in accordance with a previously established credit limit. So opening the line, or raising the limit, comes with three business days to cancel in writing; an ordinary draw does not.

How to Remember

The limit and the balance have different protections. A lender needs one of four narrow reasons to demand what you have borrowed, and any of six much broader ones to stop you borrowing more, which is why an untouched line is not a reserve.

Used in a Sentence

“Dev had been treating the undrawn portion of his home equity line of credit as a cash reserve until the lender reduced the limit after local values fell, leaving him with the balance he had already drawn and very little room behind it.”

How It Works

You apply, the lender values the property and sets a limit by applying a combined loan-to-value ceiling to that value and subtracting existing liens. You receive the disclosures and the brochure at application, and no nonrefundable fee may be charged for three business days afterward. Once the plan opens you draw as needed, interest accrues on the drawn balance at the index plus the margin, and the minimum payment during the draw period is often interest only. At the end of the draw period the balance amortizes over the remaining term.

A hypothetical example of how the limit is set and how it can be reduced. Marisa's home appraises at $500,000 and her first mortgage balance is $300,000. At a combined loan-to-value ceiling of 80% the lender will allow total liens of $400,000 ($500,000 × 0.80), so the line is set at $100,000 ($400,000 − $300,000). She draws $15,000 to redo a bathroom and treats the remaining $85,000 as money she could reach in an emergency.

Local values then fall 12%, taking the appraisal to $440,000. That clears the regulatory threshold: her available equity began at $200,000 ($500,000 − $300,000) against a $100,000 limit, a difference of $100,000, so a decline that erases $50,000 of it is a significant decline, and a fall of $50,000 in value would have been reached at $450,000. On the same 80% ceiling the lender's allowable total is now $352,000 ($440,000 × 0.80), which leaves room for a line of $52,000 above the unchanged first mortgage. Invoking the significant-decline ground, the lender reduces the limit to that figure. With $15,000 already drawn, Marisa's available credit falls from $85,000 to $37,000 ($52,000 − $15,000).

What did not happen is as important as what did. The $15,000 she already owes stays on its original terms, because a decline in the dwelling's value is not one of the four grounds on which a creditor may terminate the plan and demand the balance. She keeps the debt and loses the reserve, and the reserve was the reason she opened the line.

Nothing in that sequence requires her to have missed a payment or changed anything, which is the practical content of the freeze-versus-call distinction and the reason a line of credit belongs in a plan as a source of borrowing rather than as a source of safety. The reduction is not necessarily permanent: once the condition that justified it no longer exists, the lender must reinstate the credit, though it may put the onus on Marisa to ask.

Pros and Cons

Pros

  • You borrow only what you draw and pay interest only on that, which suits a cost that arrives in stages or may not arrive at all.
  • The rate is well below unsecured credit, because the home secures it.
  • The rate may move only with a public index outside the lender's control, so it is not repriceable at the lender's discretion.
  • Repaid amounts generally become available again, so a line can serve a recurring purpose without a new application.
  • Regulation Z requires the disclosures and brochure at application, bars a nonrefundable fee for three business days afterward, and requires a refund of application fees if a disclosed term changes before opening.
  • Opening the plan or increasing the limit carries a three business day right to rescind in writing.
  • A freeze is temporary in law. Once the condition justifying it ends, credit privileges must be reinstated, and no fee may be charged for reinstating them.

Cons

  • The lender may freeze draws or cut the limit on six broad grounds, including a significant fall in the home's value and a reasonable belief that your finances have materially changed.
  • So an undrawn line is not an emergency fund. It can be reduced in exactly the conditions that would make you want it.
  • The rate is variable, so the payment on a drawn balance rises when the index rises, with no action by you.
  • The payment can rise sharply again when the draw period ends and principal has to be repaid over the remaining term.
  • Interest is deductible only where the money buys, builds or substantially improves the home securing the plan, and only within the acquisition debt cap.
  • The home secures every dollar drawn, so a balance that could otherwise have been settled or discharged becomes a risk to where you live.
  • An ordinary draw within an existing limit carries no right of rescission.

People Also Asked

Answers to the most frequently asked questions.

Can my lender freeze my HELOC or demand the balance?
Those are two different powers with very different thresholds. Under 12 CFR 1026.40(f)(3)(vi) a lender may stop further draws or reduce the limit on six grounds, including a significant decline in the home's value, a reasonable belief that you can no longer meet the repayment obligations because of a material change in your finances, and default on a material obligation. Under 1026.40(f)(2) it may terminate the plan and demand the whole outstanding balance only for fraud or material misrepresentation, failure to meet the repayment terms, action or inaction by you that adversely affects its security, or a narrow federal rule about credit to a bank's own executive officers. A freeze also has to be lifted once the condition that justified it ends, and the lender may not charge you a fee to reinstate the line.
Is an unused HELOC a good substitute for an emergency fund?
It is a poor substitute, and the reason is legal rather than a matter of discipline. The grounds on which a lender may freeze or reduce a line include a significant fall in the home's value and a reasonable belief that your financial circumstances have materially changed, so availability can be withdrawn during precisely the conditions that create an emergency. The bar is lower than it sounds, too: the official commentary treats a fifty percent reduction in the gap between your credit limit and your available equity as a significant decline, which on its own worked example is a ten percent fall in the home's price. A line can be a useful second layer behind cash. It is not the first layer.
How is the credit limit on a HELOC decided?
By applying a combined loan-to-value ceiling to a current valuation and subtracting the liens already recorded. On a home appraised at $500,000 with a $300,000 first mortgage and an 80 percent ceiling, the lender allows $400,000 of total liens and the line is $100,000. Because the ceiling is a share of the value rather than of the equity, the borrowable amount is always less than the equity, and it moves when the valuation moves.
Can a HELOC lender raise my rate whenever it likes?
No. 12 CFR 1026.40(f)(1) permits a change in the annual percentage rate only where the change is based on an index that is not under the creditor's control and that is available to the general public. The rate therefore tracks a published benchmark plus the margin set in your agreement, and the lender cannot reprice the plan at its own discretion. What that does mean is that the payment on a drawn balance rises when the index rises.
Do I get three days to cancel a HELOC?
For the plan, yes; for an individual draw, no. Because a line is open-end credit, 12 CFR 1026.15 applies, and 1026.15(a)(1)(i) gives a right to rescind the plan when it is opened, a security interest added to an existing plan, and an increase in the credit limit. But (a)(1)(ii) removes the right for each credit extension made within a previously established limit. Notice must be given in writing, and the period runs to midnight of the third business day after the later of the event, delivery of the notice, and delivery of all material disclosures.
