What Is a Proprietary Reverse Mortgage, and Could It Be a Better Fit?

When most people hear "reverse mortgage," they picture the FHA-insured Home Equity Conversion Mortgage, or HECM. It is the most familiar option and remains an important, versatile retirement-planning tool. But the HECM is not the only type of reverse mortgage. An expanding range of privately developed programs serves homeowners whose circumstances do not fit neatly inside the traditional FHA framework. These are generally known as proprietary reverse mortgages and sometimes called jumbo reverse mortgages.

"Jumbo" is an informal industry label tied to higher-value properties, yet proprietary reverse mortgages are not only for luxury homeowners. Some serve more moderately valued homes, while others address needs unrelated to home value. What they share is a common origin: they are offered by private lenders and are not insured by FHA.

Here is the distinction worth holding onto: proprietary reverse mortgages are not necessarily better than FHA HECMs. They are distinct tools designed for different circumstances. A reverse mortgage specialist evaluates the HECM, proprietary, and reverse second options as interchangeable tools, then maps each one to your goals, timeline, and equity structure.

What Makes a Proprietary Reverse Mortgage Different?

FHA HECMs operate inside a standardized federal framework. The government sets the eligibility rules, the lending limits, and the insurance structure that backs every HECM. Proprietary reverse mortgages are developed by private lenders, subject to applicable state and federal laws and each program's own requirements. That gives lenders room to build products with different eligibility rules, lending limits, disbursement options, property guidelines, and loan structures.

There is no single universal set of proprietary reverse mortgage guidelines. Product features, underwriting, interest rates, and even basic availability vary considerably from one program to the next. Still, several features show up often enough to be worth understanding.

Higher overall loan amounts

For 2026, the FHA HECM Maximum Claim Amount is $1,249,125, set by HUD for case numbers assigned on or after January 1, 2026 (HUD). It is essential to read that figure correctly: it is not the maximum amount a homeowner can borrow. It is the maximum property value used in calculating HECM proceeds. Actual proceeds depend on the borrower's age, interest rates, available equity, financial obligations, and other factors.

Consider a homeowner with a $2 million home. An FHA HECM would generally calculate proceeds using no more than the $1,249,125 maximum claim amount, rather than the property's full market value. Proprietary reverse mortgages can recognize substantially higher home values. Depending on the program, a lender may consider homes valued well above the HECM limit, with some programs offering significantly larger loan amounts than an FHA HECM would permit. These figures are illustrative of the broader proprietary market, not universal product limits or promises of eligibility.

This matters most for homeowners whose wealth is concentrated in higher-value real estate. When a large share of net worth sits inside one home, the ability to draw on more of that equity without selling can change the shape of a retirement plan.

Potentially higher loan-to-value ratios

Some proprietary programs offer more favorable loan-to-value (LTV) ratios than FHA HECMs for particular borrowers, ages, or circumstances. That can be especially valuable when a homeowner carries an existing mortgage balance an FHA HECM cannot fully satisfy.

For example, a borrower may have substantial equity yet still owe more than an FHA reverse mortgage would allow them to refinance. A proprietary program might make the transaction possible. Higher loan-to-value ratios are not guaranteed, though. Depending on the specific situation, proprietary programs can be either more or less generous than HECMs. Private reverse mortgages don't automatically give you access to more money than government-backed options. It's important to weigh all options before making your decision.

Flexible interest rate and disbursement structures

Fixed-rate proprietary reverse mortgages exist, and some lenders offer adjustable-rate products with a line of credit. A line of credit can provide access to funds as needed rather than requiring a homeowner to borrow everything at once. Not every proprietary product offers both structures, and the available credit, future access, and any line-of-credit growth features depend on the program's actual terms.

Alternative income documentation

Some proprietary programs use alternative or reduced income-documentation requirements, including options sometimes described as simplified financial assessments. That can ease the burden for homeowners with complicated retirement-income arrangements, significant assets, or nontraditional income sources. It does not mean a borrower can simply invent income, skip underwriting, or qualify automatically. Borrowers still document their ability to meet ongoing property obligations.

Eligibility at younger ages

FHA HECMs require at least one borrower to be 62 years old. Certain proprietary reverse mortgage programs may be available to qualified borrowers beginning at age 55, depending on the lender, state, and product. That earlier eligibility can open planning opportunities for homeowners who are not yet 62.

More flexible condominium eligibility

FHA HECM financing for condominiums is subject to HUD/FHA condominium eligibility and approval requirements, and some otherwise suitable properties may struggle to meet those standards. Proprietary lenders can apply different condominium review requirements, sometimes less restrictive than the HUD standards. This can help condominium owners who might otherwise assume reverse mortgage financing is unavailable. Even so, proprietary condo loans carry their own lender-specific eligibility rules, and not every condominium will qualify.

The Reverse Second Mortgage

One frequently overlooked category deserves its own attention: the proprietary reverse second mortgage. Traditional FHA HECMs generally must sit in the first-lien position, which means any existing mortgage has to be paid off as part of the transaction. Certain proprietary reverse mortgage products can instead be placed in a subordinate lien position behind an existing first mortgage.

That positioning is especially attractive to homeowners who locked in very low interest rates several years ago. Picture a homeowner with a favorable fixed-rate mortgage. They are comfortable making their existing monthly payment and have no desire to refinance that favorable rate. Yet they have built substantial equity and would like to tap some of it for a major expense, home improvements, or greater retirement liquidity.

A proprietary reverse second mortgage may let them access additional funds without refinancing their existing first mortgage and without adding a required monthly principal and interest payment on the new reverse mortgage while its terms are satisfied. Their existing first mortgage payment continues unchanged according to the original loan terms.

A crucial caveat: the homeowner must remain financially able to maintain their existing first mortgage, property taxes, insurance, and other applicable obligations. A reverse second mortgage does not eliminate the existing mortgage payment. It simply creates another way to access equity without replacing the original loan. Reverse second mortgages are not offered in all states, and eligibility depends on specific lender and program guidelines.

A Hypothetical Case Study: The ADU Strategy

To see how this could work, consider a hypothetical example. A married couple approaching retirement owns a home worth about $1.2 million. They carry an existing first mortgage at a favorable fixed rate with a manageable monthly payment, and they want to build an accessory dwelling unit (ADU), a separate secondary living space on their property, to potentially generate rental income, accommodate family, or add future housing flexibility.

They estimate construction expenses of roughly $175,000 to $225,000, subject to local costs and permits. They are reluctant to refinance their first mortgage because they would give up an exceptionally favorable rate, and equally reluctant to take a traditional home equity loan because the added monthly payment would reduce retirement cash flow.

A proprietary reverse second mortgage could offer a third possibility. Depending on age, equity, state availability, underwriting, and lender guidelines, they might finance some or all of the project without changing their existing first mortgage and without adding a required monthly principal and interest payment on the reverse second mortgage. Any income the ADU eventually generates could help offset their housing expenses.

The strategy is genuinely attractive, but it carries real tradeoffs worth naming. Interest on the reverse second mortgage accrues and generally increases the outstanding balance when unpaid. The first mortgage payment must still be made. Construction costs can exceed initial estimates. Rental income is not guaranteed. Zoning, permitting, insurance, and property-use requirements must all be evaluated. The homeowner must confirm the proposed ADU and any rental arrangement are permitted under the reverse mortgage's terms. And borrowing against equity may reduce the unencumbered equity available in the future.

This is not necessarily the right strategy for every homeowner. It illustrates why the existence of a reverse second mortgage expands the conversation well beyond traditional reverse mortgage refinancing.

What Do Proprietary Reverse Mortgages Share With FHA HECMs?

Despite the differences, qualifying reverse mortgage programs share several fundamental characteristics. Understanding them clarifies what a reverse mortgage is, no matter who provides it.

Optional principal and interest payments. Borrowers are not required to make monthly principal and interest payments while they meet their loan obligations. They may, however, choose to make voluntary payments to manage the outstanding balance. Borrowers remain responsible for property taxes, homeowners insurance, maintenance, primary-residence requirements, and any applicable HOA or other property charges. For a reverse second mortgage, payments on the existing first mortgage remain mandatory.

No conventional fixed repayment schedule. Reverse mortgages do not carry a traditional 15-year or 30-year schedule requiring regular principal and interest payments. Instead, the loan typically becomes due upon certain events, such as the last eligible borrower permanently leaving the property, the sale of the home, the death of the last borrower, or failure to comply with loan obligations. None of this means a reverse mortgage never matures. Contractual maturity provisions and specific triggering events vary by program.

Non-recourse protection. In a non-recourse reverse mortgage, the lender's recovery is limited to the collateral securing the loan rather than the borrower's other assets. If the loan balance eventually exceeds the value of the property, the lender cannot pursue the borrower or their estate for the deficiency through personal recourse, subject to the actual terms and applicable law.

There is an important nuance. An FHA HECM's non-recourse protection is backed by its FHA insurance framework. Proprietary loan protections arise from their contractual terms and applicable legal requirements, and not every privately offered loan necessarily carries identical non-recourse provisions. Borrowers should review these protections carefully before proceeding. For reverse second mortgages, any discussion of non-recourse protection should also account for the first mortgage and its separate obligations.

The Tradeoffs: Cost, Interest Rates, and Long-Term Equity

Balance matters here, and no honest comparison hides the costs. FHA HECMs include an upfront FHA mortgage insurance premium, along with ongoing FHA mortgage insurance premiums. Proprietary reverse mortgages are not FHA-insured and therefore do not charge FHA mortgage insurance premiums. As a result, certain proprietary products may have lower upfront costs, especially when compared with a HECM that carries a substantial upfront insurance charge.

Yet proprietary reverse mortgages frequently carry higher interest rates than FHA HECMs. That gap reflects differences in product structure, financing markets, lender pricing, and risk. Lower upfront costs do not necessarily mean lower lifetime borrowing costs. Interest accrues on the outstanding loan balance and can compound over time when payments are not made, so higher rates may lead to faster loan-balance growth and less remaining equity.

The right comparison is not simply which mortgage offers the lowest interest rate or the most cash. It is which program best meets the homeowner's financial objectives, liquidity requirements, anticipated time horizon, and tolerance for long-term borrowing costs. That means comparing projected balances, upfront charges, future equity, access to funds, and available alternatives across multiple scenarios.

The right tool depends on your goals and timeline. A specialist can map each option to your situation, and for some people an FHA HECM remains the better fit, particularly for those who value potentially lower interest rates, a growing line of credit, or specific federally standardized features. Proprietary financing is one tool among several, not a universal upgrade.

Why These Programs Matter in Retirement Planning

Access to housing wealth can help homeowners in ways that fit naturally into a broader retirement plan. It can address large medical or caregiving expenses, improve liquidity without immediately liquidating investment assets, preserve favorable financing arrangements, fund suitable home modifications or accessibility improvements, manage significant one-time expenses, access more of the equity in higher-valued properties, and add housing flexibility as retirement needs evolve. These are potential planning applications, not guaranteed financial benefits.

One situation deserves special mention. A household facing substantial caregiving expenses over the next 12 to 24 months may find that a proprietary product provides greater immediate liquidity than an FHA HECM. FHA HECMs generally have first-year disbursement limitations, subject to mandatory obligations and specific calculation rules. Certain proprietary programs use alternate disbursement structures. A homeowner facing near-term care expenses may therefore need to compare not just the total available proceeds, but how much cash is accessible when it is needed.

That is a practical planning question, not a reason to push a particular product. No proprietary option is automatically the right choice for a household dealing with a serious medical diagnosis. A reverse mortgage specialist weighs the options side by side, comparing how much cash each tool makes available, when it can be drawn, and what it costs over time, so the choice reflects the client's situation rather than any single product's appeal.

What This Means for Your Retirement Plan

As we have seen, the reverse mortgage landscape is broader and more flexible than most people assume. The most important question is not whether a proprietary reverse mortgage is better or worse than an FHA HECM. It is whether the homeowner has considered the full range of available options. Retirement planning is rarely one-size-fits-all, particularly when housing wealth represents a significant portion of a family's assets.

The choice between an FHA HECM and a proprietary product comes down to goals and timelines. An experienced reverse mortgage specialist can help you compare how different strategies apply to your particular circumstances, without pressure and without promises of a single right answer.

If you are approaching or already in retirement, and you have wondered whether a traditional FHA reverse mortgage is your only choice, the answer is no. Exploring the alternatives could reveal a planning opportunity you had previously overlooked.

Reverse mortgage borrowers must continue to pay property taxes, homeowners insurance, and any applicable homeowners association fees, maintain the property, and comply with all loan terms. Failure to meet these obligations may result in the loan becoming due and payable. The loan generally becomes due and payable when the last eligible borrower dies, sells the home, or no longer occupies the property as their principal residence, subject to applicable loan terms and protections. Interest and fees accrue over time, increasing the loan balance and reducing the equity remaining in the home. Borrowers retain ownership of the home, subject to the mortgage lien and loan obligations. FHA Home Equity Conversion Mortgages (HECMs) are insured by the Federal Housing Administration.
