THE BANK OF MOM AND DAD

22/04/2026

The Bank of Mom and Dad is not a bank in any regulated sense. It does not take deposits, hold capital buffers, or answer to a prudential supervisor. What it does do is move private household balance sheets into the housing market. In practice, that means a gifted deposit, a soft family loan, a guarantor structure, a co-signed mortgage, or years of rent-free living at home while a younger buyer saves.

Different countries record different slices of that activity, so the evidence is messy, but the pattern is stubbornly consistent. 

BRITAIN REMAINS THE EASIEST MARKET TO OBSERVE BECAUSE THE FAMILY-SUPPORT CHANNEL IS TRACKED OPENLY

Legal & General’s 2024 “Bank of Family” research projects £9.2 billion of family support for home purchases in that year, helping fund about 335,000 property purchases. The average contribution is £27,400. On that measure, family money is not a side payment around the edges of the market. It is projected to support 42% of homes bought by purchasers under 55. Parents remain the main source, but grandparents and wider relatives now make up a visible share of the flow. 

The UK evidence also clarifies the legal and financial character of the money. In Legal & General’s 2023 report, 60% of contributors gave the money outright as a gift, and another 13% gave a mix of gift and loan. Most of the value went straight into deposits. That matters. In a mortgage file, a family gift often functions as the missing equity piece that allows the loan to exist at all. It is private capital doing the job that earnings could not quite do on their own. 

There is, of course, a debit entry on the other side. In the 2024 UK release, 49% of family members who gave support said they felt less financially secure afterwards, and 11% said the help had reduced their standard of living. More than a third had let adult relatives live with them rent-free. 

Legal & General estimated that this arrangement saved would-be buyers an average of £32,600. The economics are straightforward: one household delays its own comfort so another household can clear a deposit hurdle. 

HALF OF PARENTS IN THE U.S. WITH ADULT CHILDREN PROVIDE REGULAR FINANCIAL ASSISTANCE

The United States is harder to summarize with one current number, so a little discipline is needed. The strongest headline remains historical. Legal & General’s U.S. study said family and friends helped finance 1.2 million home purchases in 2018, with average support of about $39,000. On that year’s measure, the so-called Bank of Mom and Dad would have ranked as the seventh largest housing lender in the country. It is a useful benchmark, but nobody should mistake it for a live 2026 league table. 

What is current in the U.S. is the broader pattern of adult-child support. Savings.com found in 2025 that half of parents with adult children provide regular financial assistance, averaging $1,474 per adult child per month. Groceries, phones and even holidays show up in the spending mix. Strictly speaking, that is not all housing support. Economically, it still matters for housing. A parent who covers monthly living costs may be preserving a child’s ability to save a deposit, service debt, or simply stay solvent long enough to reach closing. 

The U.S. purchase market has also become less forgiving for households without a buffer. The National Association of REALTORS® reported in 2025 that first time buyers accounted for just 21% of all buyers, a record low, and that the median first-time buyer age had risen to 40, also a record. 

Among the buyers who did get through, personal savings and financial assets were the main down payment sources. The market is filtering for age, liquidity and backup capital, and while some of that backup shows up in the paperwork, a lot of it stays politely off the form. 

IN CANADA ABOUT 3/4 ADULT CHILDREN WOULD NOT HAVE QUALIFIED FOR MORTGAGE WITHOUT PARENTAL CO-SIGNING

Canada now provides one of the clearest current central bank readings of the phenomenon. Bank of Canada research published in April 2026 found that the share of first-time-buyer mortgages co-signed with a parent rose from 4% in 2004 to about 11% in 2025. More important than the share is the effect.

The Bank found that 74% of those adult children would not have qualified for their current mortgage without parental co-signing. In late 2022 data, their average purchase price was about C$709,000, roughly C$250,000 above what they could otherwise have afforded. 

AUSTRALIA HAS NO COMPREHENSIVE DATASET FOR THE SO-CALLED BANK OF MUM AND DAD YET

Australia deserves a colder reading because the data are patchier. The Productivity Commission noted in 2021 that there is no comprehensive dataset for the so-called Bank of Mum and Dad. It cited private sector estimates ranging from A$35 billion to A$92 billion and said that, if treated as a lender, the channel would sit somewhere between the fifth and ninth largest mortgage lenders. The range is wide. It tells you the channel is large, and it also tells you not to get cute about precision. 

More recent Australian survey evidence suggests a shift in form. Mozo’s 2025 report says that three quarters of parents who provide support no longer expect repayment, and that 23% let adult children live at home rent-free while they save. In other words, the “bank” is looking less like credit and more like a gift, an advance inheritance, or a quiet in-kind subsidy. The name stayed but the instrument changed. 

FIRST-TIME BUYERS IN ENGLAND WHO RECEIVED MONEY OR A LOAN FROM PARENTS BOUGHT AROUND 2.6 YEARS EARLIER THAN THOSE WHO DID NOT

Timing is where family capital quietly becomes wealth policy. A UK government-commissioned study found that first-time buyers in England who received money or a loan from parents bought around 2.6 years earlier than those who did not; in London, the gap was 4.6 years. Buying earlier means entering the amortization cycle earlier, starting equity formation earlier, and spending fewer years exposed to rent inflation. Family help does not only change whether a purchase happens but also when compounding starts.

For owners, lenders and policymakers, the Bank of Mom and Dad is a private allocation mechanism. It shifts access toward households that already sit closer to older housing wealth, liquid savings, or both.

It can keep transaction volumes alive in expensive markets. It can also widen the gap between two buyers with similar earnings and very different parents. The Institute for Fiscal Studies makes the point without embellishment: first-time buyers with university-educated homeowning parents are materially more likely to receive transfers, and those transfers are larger. 

THE GREAT WEALTH TRANSFER

There is a broader transfer of wealth frame, but it should be handled carefully. Cerulli now projects that about US$124 trillion will transfer through 2048, mostly from older generations. Not all of that will land in housing. Still, the family funded deposit, guarantee or co-sign is one of the more visible ways that inheritance starts arriving before death and while market access remains significant. 

The Bank of Mom and Dad is not a quirky side story and it is not just a meme. It is a shadow capital channel linking older household wealth to younger household market access. 

In Britain it shows up in deposits and rent‑free saving time. In the United States it is a mix of purchase help and ongoing household subsidy. In Canada it’s literally baked into mortgage eligibility. In Australia it has drifted toward gifts and in‑kind support more than formal loans. 

The paperwork looks different in each place; the economic function doesn’t. Wherever housing is expensive and credit is tight, family capital fills the gap. Where that capital is thin, people wait longer.

The pattern is global. The consequences are local, legal, and usually more expensive than they first appear.
