Borrow what you need, when you need it. Understand what can change.

A HELOC can be useful when expenses arrive in stages or when having access to a reserve matters. Flexibility is the appeal. It is also why the loan deserves more than a quick payment quote.

Before opening a line, understand both phases of the loan, how the rate is set, what fees apply, when the payment can rise, and when the lender can restrict additional borrowing.

How a HELOC works

A HELOC is open-end credit secured by the home. The lender establishes a credit limit. Subject to the agreement, available credit, and applicable law, the borrower may take advances, repay amounts, and borrow again during the draw period.

Interest is charged on the outstanding balance, not simply the full credit limit. The required payment depends on the plan. During the draw period, some plans require interest-only payments, some require principal and interest, and some use another minimum-payment formula.

The loan documents control. Do not assume that one lender's HELOC works like another lender's.

The draw period

The draw period is the part of the plan when additional advances may be available. A HELOC may provide checks, transfers, a card, or another approved way to request funds.

Ask:

• How long is the draw period?
• Is an initial advance required?
• Is there a minimum amount for each draw?
• Is there a minimum outstanding balance?
• How is the minimum payment calculated?
• Does the payment reduce principal?
• Can part of the balance convert to a fixed rate, and what fees or limits apply?
• Is there an annual, inactivity, transaction, or early-closure fee?

An unused credit limit is not cash in a bank account. It is borrowing capacity under the plan. The creditor may be able to freeze or reduce access in circumstances allowed by the agreement and Regulation Z, including certain significant declines in property value or material changes in the borrower's financial circumstances.

Do not build a plan that fails if every dollar of the line is not available later.

The repayment period

When the draw period ends, additional borrowing stops and the repayment period begins. The remaining balance must be repaid under the plan's schedule.

This transition can cause a meaningful payment increase. A borrower who made interest-only or low minimum payments during the draw period may begin paying principal over a shorter remaining term. Some plans can require a large payment at the transition or maturity.

Before closing, ask to see:

• the first-payment method;
• the repayment-period method;
• the length of each period;
• an example of the payment at more than one rate and balance;
• any balloon payment; and
• what happens if the line has a balance when the draw period ends.

The initial payment is not the whole payment story.

How a variable rate changes

Most HELOCs have a variable annual percentage rate. The rate is commonly based on a publicly available index plus a margin set by the creditor. The agreement should identify the index, margin, change frequency, minimum rate or floor, and maximum rate or cap.

A rate can change even when the borrower takes no new advance. A payment can also change because the balance changed or the plan moved into repayment.

Review these terms in the actual disclosures:

• index;
• margin;
• current APR;
• introductory APR and end date, if any;
• rate-change frequency;
• periodic and lifetime caps;
• floor or minimum APR;
• payment calculation; and
• whether negative amortization or a balloon can occur under the plan.

Do not compare only the opening rate. An introductory rate can expire.

What can a HELOC be useful for?

A line may be worth considering when:

• a home project will be paid in stages;
• the final cost is not yet known;
• the borrower wants a reserve but may not use all of it;
• expenses are expected over time rather than all at once; or
• repaid principal may need to become available again during the draw period.

That flexibility does not make every use prudent. Recurring living expenses can create a balance without a clear repayment event. Debt consolidation moves the obligation onto the home. Investment losses do not cancel the HELOC payment.

What does a HELOC cost?

Depending on the plan, costs may include:

• application, origination, appraisal, title, recording, or other closing charges;
• an annual or membership fee;
• a transaction or advance fee;
• an inactivity fee;
• a fixed-rate conversion fee;
• an early-closure or cancellation fee; and
• interest on the outstanding balance.

A no closing cost offer may mean the creditor pays certain costs in exchange for keeping the line open for a stated period. Closing early can trigger recapture. Read the agreement.

What happens to the first mortgage?

The first mortgage generally remains in place. The homeowner then has the first-mortgage payment plus the required HELOC payment and all other property expenses.

Preserving a first mortgage can be valuable. It still needs to be compared with the price and risk of the second lien. A cash-out refinance replaces the first mortgage and may change the rate and payment on the entire refinanced balance.

When a HELOC may not fit

Pause if:

• the payment works only at the opening rate;
• the plan depends on making interest-only payments indefinitely;
• the household needs guaranteed access to the unused line;
• the expense is known and one fixed repayment schedule would be easier to manage;
• a move or sale is likely before upfront costs can be recovered;
• debt is being moved to the home without a plan to stop new balances; or
• the home is the only practical safety net and repayment is uncertain.

A note from Nick

A HELOC can look simple because you do not have to take all the money on day one. I want to slow down at the places that change: the index, payment, draw period, repayment period, and access to unused credit.

We will compare the line you could open with the balance you actually expect to carry. Those are different numbers.

Walk through both phases before you open the line

Bring any HELOC offer or disclosure you are comparing. Nick will help you identify the rate formula, payment changes, fees, and questions that need a current answer.
