What is a shared appreciation mortgage and why are they controversial?
A shared appreciation mortgage (SAM) is an older type of equity release, mostly sold in the late 1990s, where the homeowner received a loan (often interest-free) in exchange for giving the lender a share -- typically 75% -- of any future increase in the property's value. Because house prices have since risen dramatically, many original borrowers or their families now owe far more than the original loan amount, making SAMs highly controversial and the subject of long-running legal disputes.
Full answer
Shared appreciation mortgages were a niche form of equity release offered by a small number of UK lenders, primarily Barclays and Bank of Scotland, mainly between 1996 and 1998, and while no longer sold today, they continue to cause serious financial difficulty for the surviving original borrowers and their families decades later. **How a SAM worked** Under a typical SAM, a homeowner (usually an older person wanting to release some equity without ongoing monthly repayments) received a cash loan, often with NO interest charged at all, in exchange for agreeing to give the lender a proportion of any increase in the property's value between the time the loan was taken out and when the property was eventually sold (typically on the borrower's death or move into care) -- a common arrangement gave the lender 75% of any increase in value in return for a loan of 25% of the property's value at the outset, though the exact split varied by product and provider. **Why they seemed attractive at the time** Without the burden of compounding interest that affects most other equity release products, SAMs appeared to offer a much cheaper way to release equity, particularly appealing to older homeowners wary of interest costs snowballing over many years -- borrowers weren't required to make any monthly repayments, and the arrangement was marketed as a fair way to share in future property gains rather than charging conventional interest. **Why they became so controversial** UK house prices rose dramatically over the following two to three decades, in some areas multiplying several times over -- because the lender was entitled to a LARGE PROPORTION (commonly 75%) of this entire increase in value, not just a proportionate return on the original loan amount, the amount ultimately owed when the property was sold has, in many cases, turned out to be many multiples of the original loan received, sometimes representing effectively enormous implied "interest rates" once expressed as an annualised return on the lender's original outlay. **Legal challenges and campaign groups** Affected families and campaign groups (including the SAM Action Group) have pursued legal action against the lenders, arguing the products were mis-sold, unfair, or that borrowers weren't properly warned about the scale of the potential future cost given how disproportionate the lender's share of appreciation could become relative to the modest original loan -- some cases have proceeded through the courts, though outcomes and any compensation have varied and the overall legal position remains a live and evolving issue. **Impact on inheritance** Because the lender's share is calculated on the FULL increase in property value, families of SAM borrowers have frequently found that a very large proportion of what would otherwise have been an inheritance is instead owed to the lender when the property is eventually sold, sometimes leaving considerably less for beneficiaries than they had expected. **No longer sold, but existing SAMs remain in force** Shared appreciation mortgages have not been offered as new products for many years, but existing SAMs taken out in the late 1990s remain legally binding and continue to accrue the lender's share of appreciation until the property is eventually sold, meaning the issue continues to affect elderly borrowers and their families today. **Practical tip** If you or a family member has an old shared appreciation mortgage, get independent legal and financial advice well before any anticipated sale of the property (for example, before a move into care), as understanding exactly how the appreciation share will be calculated, and whether any grounds exist to challenge or renegotiate the terms, can make a very significant financial difference.
