What it means
A reverse mortgage lets an older homeowner convert equity into cash without monthly payments, the balance falling due when the home is sold or the borrower leaves it. The dominant US version is the FHA-insured Home Equity Conversion Mortgage, which caps the home value it will recognise.
The proprietary reverse mortgage is the private market's answer for homes above that cap. Offered by lenders under their own terms, without federal insurance, proprietary products can lend against multi-million-dollar properties and sometimes accept younger borrowers or different payout structures.
The absence of FHA insurance cuts both ways: borrowers skip the insurance premiums, but lose the programme's standardised consumer protections, making lender-by-lender comparison essential. The Consumer Financial Protection Bureau's servicing guidance for private-label reverse mortgages shows regulators watching this market: borrowers retain obligations like taxes and insurance, and servicers must follow written procedures when those are missed.
The risks mirror the federal product's: the balance grows as interest accrues, equity shrinks over time, and heirs inherit a home with a debt to settle, usually by selling it. Costs deserve special scrutiny in the private market, where fees, margins, and terms vary widely and the federal programme's standardisation is absent.
For a non-finance reader, a proprietary reverse mortgage is the bespoke suit of equity release: tailored for expensive homes, but without the government label guaranteeing the stitching. Counselling requirements vary where the federal wrapper is absent.
Some states impose their own independent-counselling rules on proprietary loans, and a borrower should treat any lender that discourages outside advice as a warning. The jumbo niche exists because housing wealth concentrates in expensive markets.
A modest federal cap leaves owners of high-value homes equity-rich and programme-poor, which is precisely the gap private lenders designed these products to fill. Non-recourse features deserve explicit checking.
The federal programme guarantees borrowers never owe more than the home's value; proprietary lenders may offer the same protection, but it is a term to verify, not assume. Estate planning belongs in the decision.
Children expecting the home should understand the growing balance early, not at probate, when the options have narrowed to selling or refinancing under deadline.
In practice
Real-world examples.
Example
An owner of a $3 million home uses a proprietary reverse mortgage to access equity beyond the federal programme's cap. The cap, not the equity, forced the choice.
Example
A borrower compares two proprietary offers and finds the lower-margin loan more expensive once origination fees are included. A break-even calculation over the expected years in the home shows which offer is cheaper.
Example
Heirs sell a home to settle a proprietary reverse mortgage balance after the borrower's death, keeping the remaining equity. The lender is repaid from the sale proceeds, and the family decides on the sale timetable within the loan terms.
Formula
Calculation
The loan balance grows as interest and fees accrue against no monthly payments, and falls due when the borrower sells, moves out, or dies. Advances are sized from the home's appraised value, the borrower's age, and the lender's private terms. Balance after n years = amount drawn x (1 + annual rate) to the power n.
Worked example. A borrower draws $600,000 at a hypothetical 6% annual rate, compounding, with no payments. After 10 years the balance is $600,000 x 1.06^10 = $600,000 x 1.7908, which is about $1,075,000. If the home is still worth $2,800,000, the remaining equity before selling costs is $2,800,000 - $1,075,000 = $1,725,000. The balance has nearly doubled, which is why heirs should understand it early.Case study
Seen in the real world.
This case study is fictional and illustrative. A made-up 74-year-old in California owns a $2.8 million home outright and wants $600,000 for care costs and gifts to grandchildren. The federal HECM cap recognises only a fraction of the value, so her adviser presents a proprietary reverse mortgage with up to $900,000 available at a fixed margin, with no mortgage insurance premium. The comparison session is thorough because the product is not standardised: a second lender quotes a lower margin but heavier origination fees, and the break-even between them sits at year nine.
She takes the first lender's offer, drawing $600,000, with a set-aside ensuring property taxes and insurance are paid, the exact obligation the CFPB's servicing guidance warns borrowers about. Eleven years later she moves to assisted living, and with interest compounding at about 5.7% the loan falls due at roughly $1.1 million. The house sells for $3.4 million, settling the debt with ample proceeds for her estate. Her daughter, the executor, tells the family lawyer the product worked as designed, but only because her mother had compared two term sheets line by line, which the private market had made necessary.
Watch out
Common mistakes.
- Assuming federal protections apply; proprietary loans lack HECM insurance and standardisation, so terms and safeguards vary by lender.
- Comparing margins while ignoring fees; private-market pricing hides in origination charges, and break-even analysis beats headline rates.
- Forgetting ongoing obligations; taxes, insurance, and maintenance still fall on the borrower, and missed payments can trigger default even with no monthly mortgage bill.
Questions
People also ask.
What is a proprietary reverse mortgage?
A private reverse mortgage offered under a lender's own terms, without FHA insurance, typically serving homes worth more than the federal programme's limits.
How does it differ from a HECM?
HECMs are federally insured, standardised, and capped; proprietary loans are uninsured, lender-designed, and can reach higher home values with varied terms.
What are the main risks?
A growing balance that erodes equity, variable costs and protections across lenders, and the continuing duty to pay taxes, insurance, and upkeep.
