Reverse Mortgage vs. HELOC: Compare Payments, Costs and Risks

A reverse mortgage and a home equity line of credit, or HELOC, both let you borrow against your home. But they work in very different ways.

A HELOC usually requires monthly payments. Its rate is often variable, so payments can rise. A reverse mortgage usually does not require monthly principal and interest payments. Instead, interest and fees are added to the balance, so the amount owed grows over time.

Neither option is automatically better. The right fit depends on how long you expect to stay in the home, whether you can handle monthly payments, and how much equity you want to keep.

The two loan structures

How a HELOC works

A HELOC is a revolving line of credit secured by your home. You can borrow as needed, up to the lender’s limit, during a draw period. Many draw periods last about 10 years.

You make payments after you borrow. During the draw period, some plans may allow interest-only payments. Later, the repayment period begins, and payments may include both principal and interest.

Most HELOCs have variable rates. This means your rate and payment can change as market rates move. You also need enough income, credit, and home equity to qualify.

How a reverse mortgage works

A reverse mortgage is also secured by your home. The most common type is a Home Equity Conversion Mortgage, or HECM. HECMs are federally insured and are generally available to homeowners age 62 or older who meet the program rules.

With a HECM, you normally do not make monthly principal and interest payments. You still must pay property taxes, homeowners insurance, and other required property charges. You must also maintain the home and use it as your principal residence.

Interest and fees are added to the loan balance each month. As the balance rises, your remaining home equity usually falls. Other reverse mortgage products may use different rules, so compare the written terms.

Payments and rates: the biggest cash-flow difference

The clearest difference is what happens each month.

A HELOC creates a required payment once you borrow. If the rate is variable, the payment may rise. A low payment during the draw period can also increase when the repayment period begins.

A reverse mortgage can reduce pressure on monthly cash flow because regular principal and interest payments are not usually required. That does not make the loan free. Interest and fees continue to build, and property-related bills must stay current.

Ask a lender to show payment examples under several rate scenarios. For a HELOC, include a higher rate and the start of the repayment period. For a reverse mortgage, ask how the balance may grow over the number of years you expect to stay in the home.

Compare costs over the time you expect to keep the loan

Do not compare only the interest rate. Review the full cost over your likely time in the home.

HELOC costs vary by lender. They may include an application fee, appraisal, annual fee, early closure fee, or other charges. A HELOC can have lower upfront costs than a reverse mortgage, but a variable rate creates uncertainty.

HECM costs can include an origination fee, third-party closing costs, mortgage insurance, interest, and possible servicing fees. Some costs can be paid from loan proceeds. That reduces the cash available to you and increases the balance.

A reverse mortgage may be a poor fit for someone likely to move soon because upfront costs are spread over fewer years. A HELOC may also be costly if payments become hard to afford or the balance stays high for a long time.

What happens if you move or stop living in the home?

A move can trigger repayment under either option.

If you sell a home with a HELOC, the balance is normally paid from the sale proceeds. You may also face an early closure fee if your agreement includes one.

A reverse mortgage generally becomes due when the last eligible borrower no longer lives in the home as a principal residence. Death, sale, or a permanent move can trigger repayment. Certain absences from the home can also matter under program rules.

If keeping the home in the family is important, discuss the plan with heirs before borrowing. Ask what choices they would have, how much time they may receive, and what documents the servicer will require.

Decision matrix: which structure may fit the household?

You can comfortably make monthly payments

A HELOC may be worth comparing when you need flexible access to funds and can handle changing payments. It may also fit when you expect to repay the balance in a clear time frame.

Monthly cash flow is tight

A reverse mortgage may deserve a closer look if avoiding a new monthly principal and interest payment is important. You still need enough cash to cover taxes, insurance, maintenance, and other required charges.

You expect to move within a few years

High upfront costs can make a reverse mortgage less attractive for a short stay. Compare lower-cost choices and the cost of selling before deciding.

You want to preserve more equity

A HELOC balance can fall as you repay principal. A reverse mortgage balance usually grows because interest and fees are added. Either loan reduces the equity available after the debt is repaid.

You need money in stages

Both products can offer line-of-credit access, but the rules differ. Compare how much you can access, how the available amount may change, when draws end, and what happens if you do not use the full line.

Questions to ask before signing

Request written loan estimates and product terms. Then review these questions with a qualified adviser or housing counselor:

What payment is required now, and what could it become later?
What rate can change, how often can it change, and is there a cap?
What are the upfront and ongoing costs?
How much cash will be available after fees and existing liens?
What happens if one spouse dies or moves to long-term care?
What occupancy, tax, insurance, and maintenance rules apply?
Can the lender freeze or reduce access to a HELOC?
What happens to the remaining equity when the loan is repaid?
How will the choice affect heirs or a future move?

Alternatives to compare

Borrowing against your home is only one way to cover an expense. Depending on the need, you might also compare a fixed home equity loan, a cash-out refinance, a smaller repair loan, payment plans, downsizing, or local assistance programs.

The lowest monthly payment is not always the lowest total cost. The option with the lowest upfront cost may not be best over many years. Compare the same dollar amount and time period across every offer.

Bottom line

A HELOC may offer flexible borrowing, but it brings required payments and often a variable rate. A reverse mortgage may avoid monthly principal and interest payments, but its balance grows and the borrower must meet property and occupancy rules.

Start with two questions: How long do you expect to stay in the home? Can your household safely carry a required monthly payment if rates rise?

Use those answers to narrow the field. Then compare written terms, review the decision with a qualified adviser or HUD-approved housing counselor, and choose only after you understand the effect on your cash flow and home equity.
