Guest article from Chris Smith, CEO and Founder of BLOXX.
For the past two years, housing policy and housing finance have fixated on one variable: interest rates. Lower them, the argument goes, and affordability returns; hold them higher, and the buyers retreat. But that framing is now out of date.
Even if interest rates halved tomorrow, millions of people would still be locked out of homeownership, and the reason is structural rather than cyclical. The problem is the mechanics of debt-based home buying itself, colliding with higher deposits, outdated underwriting, refinancing risk and fragile household balance sheets. So, the price of money argument isn’t really relevant for homeownership anymore.
Across the developed world, homeownership rates are falling despite enormous pools of capital sitting in residential property. In the UK, ownership has dropped from around 70% at its peak to roughly 63% today, this equates to about 4.6 million homeowners lost. There’s a similar story happening in the US, Australia and New Zealand.
This shift makes one thing clear: the market is ready for a new solution. With the average UK deposit now around £55,000, and nearly half of first-time buyers relying on family support, the challenge is no longer about demand, it is about redesigning the path to ownership.
The mortgage problem most people never see
To understand why, we have to strip back the traditional mortgage model. Repayment on mortgages doesn’t deliver ownership in a straight line – it’s front-loaded with interest. In the early years of a typical 25 or 30 year mortgage, the majority of monthly payments go to servicing the bank’s funding cost (interest), not building the buyer’s equity. In a typical long-term mortgage at today’s rates, a borrower can spend five years making payments and still have repaid well under 10% of the original loan. That can be tens of thousands paid out, and surprisingly, very little ownership gained for the cost.
That process once made sense as it was designed for an economy of long job tenures, predictable wages, stable house prices and infrequent moves. It fits far less in the current world we live in, where buyers are stretched to meet higher deposits, fixed rate deals expire into different interest rate environments, people move more often for work or family, and income changes. Redundancy, illness, and childcare are common rather than exceptional circumstances.
When life throws curveballs early in the mortgage journey, borrowers can discover they have far less equity than they would. Transaction costs, price volatility, or a forced sale can wipe out years of payments, and what was sold as security quietly becomes fragile.
The good news is that recognising these weaknesses is the first step toward building something better, and an evolved housing system.
A debt system colliding with demographic reality
The consequences are now visible in the data, over the past decade millions of younger adults have been pushed out of ownership entirely, leaving close to 8 million people renting in the 25 to 39 age group alone. Children of homeowners are now more than twice as likely to own a home as children of renters, hard-wiring inequality across generations.
All of this is happening while more than $300 trillion of capital sits in residential property globally, delivering returns to asset holders even as access to ownership narrows.
The system is not lacking money, but it’s lacking structures that allow capital and households to meet without excessive leverage. This mismatch of capital and shrinking ownership is a crisis, but it is one of the greatest opportunities in the history of housing finance and acts as a chance to rebuild access, and expand ownership for millions of families.
Why equity-first housing is gaining attention
In response, a different design pattern is beginning to emerge: equity-first home finance. Instead of borrowing most of the purchase price and slowly earning ownership, households accumulate equity directly over time, and long-term capital holds the remaining stake, sharing both the upside and downside.
Homeowners are not tenants, and they are not debtors; they are co-owners from day one, and are increasing their share through regular payments rather than paying off interest on a loan. This isn’t shared ownership dressed up with better UX or a deferred mortgage by another name. Equity-first models reframe housing from a liability-heavy balance sheet product into a shared-equity arrangement aligned with how people actually live and earn today.
With 1.2 billion renters globally and a housing market in need of new solutions, we enter a defining moment for fintech leaders to rebuild access to ownership, and to connect global capital directly into homes in a more efficient and equitable way.
What must be true for these models to work responsibly
Equity-based housing only works if it is built with discipline. Incentives must genuinely align, homeowners must benefit from price appreciation as they build equity, while the capital provider must accept exposure to downside risk. Any model that promises access without exposing capital to loss is mis-selling.
Secondly, consumer protections matter more, and clear rules on how house price movements are shared are the core principles of the product. Thirdly, fintechs must confront the operational complexity they often underestimate: ongoing valuation, liquidity management, governance rights, dispute resolution, and servicing when things go wrong.
Finally, scale depends on credibility. Institutional capital will only engage if structures are legally dependable, governable, and repeatable across global markets.
If done well, these models have the potential to unlock one of the largest untapped opportunities in global finance, while delivering a realistic path back into ownership.
What this means for banks, investors, and policymakers
If housing does move towards hybrid equity structures, the implications across the board are significant, and various roles within the industry are set to change. Banks may evolve from primary risk holders into liquidity and infrastructure providers. Brokers could shift from loan originators to long-term ownership advisors. Asset managers will gain access to a new residential asset class, fully backed, scalable and directly linked to real-world outcomes.
For policymakers, equity-first models offer a third pathway between renting and mortgage ownership, reducing reliance on subsidies and expanding access. The biggest risk, however, is not regulatory overreach but silence, housing is too systematically important, and too personal, for experimentation without clear guidelines.
But with the right frameworks, policymakers have a chance to power innovation that increases ownership, strengthens communities, and makes housing finance work again for modern households.
The choice housing finance can no longer avoid
Housing finance is already changing, and the only question is whether it does so intentionally or not. Debt-only ownership models are misaligning with reality, labour mobility and capital, optimising traditional mortgages alone will not fix the issue.
But within this disruption sits a huge opportunity to connect the world’s deepest pools of capital directly into homes, redesigning ownership to work for modern households, not against them.
The decisive choice now sits with global capital allocators, regulators and governments. They have an opportunity to support the evolution of housing finance by backing models that expand access to ownership and better reflect how people earn, move and build wealth today.
Regulation needs to protect ownership itself as an outcome, either equity-first models are allowed to mature into a credible pathway to homeownership for working people, or ownership continues to erode by default as more housing ends up in the hands of larger corporate landlords.
This future broadens ownership, unlocks capital, and rebuilds the promise of homeownership.
