Reverse Mortgages: What You Are Actually Selling

No payment means the interest has nowhere to go

An ordinary mortgage charges interest each month and receives a payment each month, and the payment is larger than the interest, so the balance falls. A reverse mortgage charges interest each month and receives nothing, so the interest is added to the balance and charged interest on next month. That single structural difference is the whole article. It turns a declining series into a compounding one, and compounding at a rate near seven percent is not a gentle process: our balance doubles every 9.93 years, so it is roughly twice the opening figure at year ten, four times at year twenty and eight times at year thirty.

The growth rate is not just the interest rate. On the American programme the balance accrues the note rate plus the annual mortgage insurance premium, and both compound. At an assumed note rate of 6.5 percent and an insurance premium of 0.5 percent, the balance grows at 7 percent nominal, which compounded monthly is 7.23 percent a year. Rate matters enormously here because there is no payment to absorb the difference: at a 5 percent note rate the year-twenty balance would be $530,403 rather than $714,857, and at 8 percent it would be $963,100. Always ask for the total accrual rate rather than the headline rate, and ask what happens to it if the loan is variable.

The crossover, drawn properly

Put two curves on the same axes. The debt starts at $177,000 and grows at 7.23 percent, deterministically. The house starts at $400,000 and grows at whatever the market does. Where they cross, the household's equity in its own home becomes zero. On a flat market that happens after 11.68 years. If prices fall by one percent a year it happens after 10.21 years. If prices rise two percent a year it happens after 16.31 years, and even at three percent a year — a rate few markets sustain in real terms over two decades — it happens after 20.26 years. There is essentially no plausible price path on which the crossing does not occur within an ordinary retirement.

The reason the crossing is so hard to avoid is that the two curves are not in a fair race. The debt compounds at 7.23 percent on a number that only grows. The house appreciates on a much larger number, which is what buys the borrower time at the start, but appreciation is neither guaranteed nor typically that fast in real terms. Read the two rates against each other: for the debt never to catch the value, house prices would need to rise faster than 7.23 percent a year for as long as the borrower lives in the property, and to do so from a starting point where the debt is already 44 percent of the value.

It is worth stating plainly what the household received in exchange. The borrower drew $160,000 in cash. By year twenty the accrued interest and insurance total $537,857, and the estate's position on a flat market is zero. Whether that is a bad outcome depends entirely on what the $160,000 did. Twenty years of staying in one's own home, of paid-for care, or of not having to sell in a bad month, are real goods that a spreadsheet does not price. What the spreadsheet can do — and this is its only job here — is make sure nobody is surprised at year twelve.

Non-recourse: what it does and does not guarantee

The core protection is real and should not be understated. Under the American programme the borrower or the estate never owes more than the loan balance or the value of the property, whichever is less, and no asset other than the home can be reached for the shortfall. French law states the same principle in a single sentence: the debt of the borrower or of their successors may never exceed the value of the property assessed at the term of the contract. On our flat-market case at year twenty, the balance is $714,857 and the property is worth $400,000; the estate hands over the property and the $314,857 gap is borne by the insurance or the lender, not by the family.

What it does not do is preserve anything. Non-recourse caps the downside at zero; it does not put a floor above zero. On three of our four price paths the family inherits an obligation to hand over a house and nothing else. It also does not guarantee that the borrower keeps the home: it governs what is owed at the end, not whether the end arrives early. And it does not protect against the risk that the borrower outlives the usefulness of the money — drawing a lump sum at seventy and needing a further sum at eighty-five is a common and unhappy sequence, because by then the borrowing capacity has been consumed by the compounding.

The obligations that can still end it early

There is no monthly payment, which is not the same as no obligations. Under the American programme the borrower must keep the property as a principal residence, must pay property taxes and hazard insurance, and must maintain the property in reasonable condition. Failing any of those is an event of default that makes the loan due and payable, and property charges are the most common cause. The programme's own response to that risk is a financial assessment before the loan is made, which may require part of the proceeds to be set aside in a reserve to pay taxes and insurance — money the borrower can then no longer spend on anything else.

The residence condition is the one that catches families out. A borrower who moves into care for more than a defined period is generally no longer occupying the property as a principal residence, and the loan becomes due — at exactly the moment the family is least able to deal with a property sale. Related to it is the position of a spouse or partner who is not a borrower: rules on whether a surviving non-borrowing spouse may remain in the home have changed over time and are highly specific, and this is the single most important question to have answered in writing before signing anything. Do not accept a verbal assurance on it.

Heirs, and where the fees go

When the loan becomes due, the heirs have a defined set of choices: repay the balance and keep the house, sell it and keep whatever exceeds the balance, or hand it over. Under the American programme, heirs wishing to keep the home when the balance exceeds the value may buy it for 95 percent of the appraised value rather than the full balance — a provision that only bites after the crossover. On our flat-market case the balance passes 95 percent of the value at year 10.95, a little before it passes the value itself at 11.68. Deadlines for deciding are short, and they run from the triggering event rather than from when the family finds the paperwork.

The fee structure deserves to be seen as a whole rather than line by line. On our case the upfront insurance premium is $8,000, the origination fee $6,000 and closing costs $3,000, which is $17,000 — 4.25 percent of the house value and 10.63 percent of the cash the borrower actually received. Because all of it is financed, it also begins compounding at 7.23 percent on day one: the $17,000 becomes $68,659 of balance by year twenty on its own. Then the annual insurance premium adds half a point to the accrual rate for the life of the loan. None of these charges is hidden — they are disclosed — but they are quoted against the house value, where they look modest, and their weight is against the money you get, where they do not.

The markets do not have the same instrument

The American Home Equity Conversion Mortgage is a federally insured programme with a mandatory independent counselling session before an application can be made, a minimum age of 62, a statutory non-recourse guarantee and the insurance premiums that pay for it. That combination — public insurance plus compulsory counselling — is unusual, and it is what makes the product a mainstream one there rather than a niche one.

France has a different instrument with the same economics. The prêt viager hypothécaire is defined in the consumer code as a loan to a natural person, secured on a residential property, whose principal and annually capitalised interest can only be demanded at death or on sale or dismemberment of the property. The non-recourse cap is explicit in the code. There is no public insurance scheme behind it and no counselling requirement of the American kind, and the market has remained small. Spain regulates the hipoteca inversa under a 2007 statute that requires the borrower to be 65 or older or to be in a situation of dependency or recognised disability, and — this is the notable feature — makes independent advice compulsory before signing. Italy's prestito vitalizio ipotecario, reserved to owners over 60, was reshaped by a 2015 statute and a 2015 implementing decree that set out the information and the settlement procedure.

Germany and Portugal are the two where a reader should be most careful, because there is no mainstream statutory product of this kind in either and what is offered instead may be something structurally different — a sale with a retained right of occupation, a partial sale, an annuity arrangement. Those are not reverse mortgages: they transfer ownership, or part of it, rather than creating a debt against it, and the protections described in this article do not carry across. If you are being offered equity release in a market without a dedicated statutory framework, the first question is not what does it cost but what exactly am I signing away, and the answer must be checked in the contract and with an adviser who is not being paid by the seller.

Frequently asked questions

Is a line of credit safer than taking a lump sum?

Arithmetically, drawing later means less compounding, so yes, in that narrow sense. Drawing $1,000 a month for twenty years instead of $160,000 up front — $240,000 of cash in total — produces a balance of $589,585 at year twenty against $714,857 for the lump sum, despite delivering half as much again in cash, because the early draws are the ones that compound longest. The trade is that a line can be reduced or frozen in circumstances set out in the contract, and a lump sum in hand cannot. Read what the lender may do to an undrawn line before treating it as a reserve you can count on.

Can the lender take the house while the borrower is alive?

Not because the balance has grown — growth alone is never a default — but yes, if one of the continuing obligations is breached. Failing to pay property taxes or hazard insurance, letting the property fall below the required condition, or ceasing to occupy it as a principal residence can all make the loan due and payable while the borrower is living. That is why the mandatory counselling in the American programme spends time on property charges and why a set-aside may be required. If money is tight enough that the taxes are at risk, a reverse mortgage does not remove that risk; it converts it into a risk of losing the home.

What happens if house prices fall a lot?

For the borrower and the estate, nothing changes financially, and this is where the non-recourse cap genuinely earns its premium: the debt is limited to the value however far the value falls, so the loss lands on the insurer or the lender. On our path of prices falling one percent a year, by year twenty the balance is $714,857 against a value of $327,163, and the $387,694 shortfall is not the family's problem. What does change is timing: a falling market brings the crossover forward — 10.21 years instead of 11.68 — so any plan that depended on selling with equity left needs to be abandoned earlier than expected.

Is there a cheaper way to get the same money?

Often there is, and the alternatives should be priced before the product is. Selling and moving to something smaller realises the whole of the net equity rather than a fraction of it and starts no compounding at all, at the price of leaving the home. A conventional loan or a credit line secured on the property is cheaper per unit borrowed but requires income to service and can be withdrawn. Help from family, a local scheme for older homeowners, or a deferred property-tax programme where one exists may cover the specific need at a fraction of the cost. The question worth asking is what the money is for, because a temporary need answered with a permanent instrument is the most common way this goes wrong.

Why is counselling mandatory in some markets and not others?

Because the product is sold to people whose circumstances make an unhurried decision hard, and legislators in some markets concluded that disclosure alone was not enough. The American programme requires a counselling session with an approved counsellor before an application; Spanish law requires independent advice before signing a hipoteca inversa. Where no such requirement exists — France and Italy have statutory frameworks without an American-style counselling mandate — the burden of arranging a genuinely independent second opinion falls on the borrower and the family. Arrange one anyway. The cost of an hour with an adviser who earns nothing from the outcome is trivial against the numbers in this article.
