“Fair-share appreciation” models to build wealth through homeownership
Nine innovative financial instruments for adaptation, nature and energy access
COP Watch: Mapping impact opportunities in Brazil

Featured: Ownership Economy

From affordable home ownership to ‘fair-share appreciation’ and generational wealth. The 50-year home mortgage is an idea whose time… would saddle buyers with a pile of debt and reduce their ability to build equity in their homes. President Trump’s rush to trumpet Federal Housing Finance Agency chief Bill Pulte’s adulatory poster sent brokers, realtors and prospective borrowers scurrying to slide the levers on their online mortgage calculators. What they found when they amortized a loan over 50 years, versus the standard 30, was added debt that would extract, not build, wealth for families making the biggest purchase of their lives. But the president’s trial balloon, a response to last week’s voter uprising over “affordability,” opened a broader conversation about better ways to not only help families get into their first house, but into an appreciating asset that can provide a foundation for financial prosperity. A new crop of “shared appreciation” solutions that slide those levers in innovative ways are going to market in select cities around the country, including Washington, DC, Detroit, Philadelphia, Raleigh-Durham and Charlotte. The new models seek to correct for some of abuses of earlier models of shared appreciation, sometimes called “home equity investments,” which have been criticized as tilted toward investors rather than home buyers. Call the new models “fair-share appreciation.”

Tools of dignity. “Creating prosperity for all is front and center on the minds of people across the country. Home ownership is one of the pillars, and it’s just out of reach,” says Utah-based investor Jim Sorenson, a major backer of Homium, a New York-based digital home-equity lender that has completed a pilot project that helped 20 homebuyers purchase properties in Colorado. “The environment now is more receptive, so we view that as a positive,” says Sorenson. “We hope that these things are carefully looked at because you can also create more problems with bad policy.” (Disclosure: Sorenson Impact Foundation is an investor in ImpactAlpha and sponsors our Ownership Economy coverage.) Homium’s shared-appreciation notes function as a second-mortgage, but without interest. Increasing the downpayment reduces the monthly payment for homebuyers and eliminates the need for private mortgage insurance. Homium’s payout comes from its share of the downpayment, on the same terms as the homeowners. “They’re going to have the same cost per month as the 50-year proposal, and they will have a $500,000 more money, compounded over time, that they didn’t spend on interest,” Homium’s Tommy Mercein tells ImpactAlpha. “And they will accrue equity at a faster rate.”
Brick by brick. Helping first-time buyers get into the market is not a new idea. Down Payment Resource has tracked more than 2,000 programs that have launched since 2008 to help homebuyers with their down payments and closing costs. In Denver, the Dearfield Fund has provided up to $40,000 in down-payment assistance for a household, helping hundreds of buyers purchase their first homes. The interest-free loans are paid back when homeowners sell or refinance, along with 5% of the home’s appreciated value. Ownify helps first-time buyers get into the market with an even smaller stake, letting them build equity over time. The Raleigh-based company buys the house a buyer chooses and issues 10,000 shared-equity “bricks” representing a home’s value. Buyers enter with as little as 2%, or 200 bricks. That’s $8,000 for a $400,000 house – far less than the typical down payment. “Our thesis is that, rather than more debt, a shared-risk, shared-equity model is the better path into ownership for young people, for first-time buyers, especially for folks in the middle of the income pyramid,” says Ownify’s Frank Rohde. He calculated that a 50-year loan would add more than $32,000 in housing costs over five years, compared with Ownify’s approach. The good news of this week’s swirl of publicity around the proposals: “It elevates the discussion on housing affordability,” says Rohde. “The bad news is the 50-year mortgage is a stupid idea.”

Dealflow: Adaptation Finance

Global Innovation Lab backs new models to close adaptation and nature finance gaps. The Global Innovation Lab for Climate Finance has rolled out nine new financial instruments designed to steer capital toward climate solutions in emerging economies. The cohort, announced last week in São Paulo, targets some of the most persistent gaps in climate finance: adaptation, nature protection and energy access. “No amount of concessional capital substitutes for a good enabling environment,” Maria Ruiz of the Climate Policy Initiative, which runs the Lab, told ImpactAlpha. The instruments are designed with “a greater focus on local capital mobilization – anchoring the thesis in country priorities, real economy needs and local investor appetite.”

Smallholder finance. Four new instruments are based in Africa and Asia, targeting gaps from smallholder agriculture to early-stage climate technology. Philippines-based Mayani is creating a fund to lend to farmer cooperatives, providing smallholder farmers with capital to adopt climate-resilient practices and crop insurance, and receive help securing buyers for their produce. IREN Agri, a partnership between Ksapa and Société Générale, combines medium-term finance, technical assistance, digitalization and offtake agreements to help farming communities in West Africa build climate resilience. In India, Green Artha’s Clean Economy Fund uses a blended equity model to back first-of-a-kind demonstration projects and attract follow-on investment for novel climate tech solutions.
Nature-based innovation. In Colombia, Strata Advisors is developing a parametric insurance model that finances wildfire response efforts to protect critical water sources. In Brazil, Silva is pioneering a financial instrument tailored to native seedling nurseries, providing purchase guarantees and long-term contracts to stabilize grower incomes and strengthen reforestation supply chains. In Argentina and Colombia, Meliquina is developing renewable energy projects with Indigenous communities that include shared decision-making and equity ownership. And the Tropical Resilience Fund, managed by London- and Brazil-based Impact Earth, will provide asset-backed revenue-based financing, convertible debt and bridge loans to conservation and restoration ventures.
More.

Signals: COP Watch

ImpactAlpha weekly COP Watch, in partnership with Aliança Pelo Impacto, Brazil’s national advisory board for impact investing, is tracking the world’s largest climate gathering. Get in touch with events, news, tips and guest posts from COP30.

How Mútua is using AI to map impact opportunities in Brazil. Brazil is pitching the climate summit underway in Belém as the “COP of implementation.” Past COP summits have failed to mobilize the volumes and types of capital needed to meet the climate crisis. “There is a problem of information asymmetry, and specifically, the differences in culture and language between sectors of society,” says Lucas Matarazzo of Mútua, a São Paulo-based impact data company that is helping investors develop impact strategies. Mútua, one of several Brazilian initiatives to unblock impact and climate capital, uses public data, expert reviews and artificial intelligence to map startups, small businesses and nonprofits against the UN’s Sustainable Development Goals, IRIS+ metrics and other frameworks. It has financial backing from local Brazilian investors Co-Capital, Din4mo and Oogway Capital to provide investors with the “decision-grade intelligence” needed to evaluate opportunities, and coordinate with other investors.

Tech-enabled strategies. A recent survey by The ImPact found that while wealthy families in Latin America have deployed around $1.4 billion in impact investments, lack of team expertise and understanding of impact management are obstacles to deploying more. Matarazzo tells ImpactAlpha that Mútua’s partners working with family offices see AI and mapping tools as “key for shaping the future and guiding how [to] allocate capital.” Mútua emphasizes its purpose as a systemic tool rather than a deal-sourcing portal, recognizing the market skepticism of investment “match-making” services, which have had mixed results.

Brazil’s impact finance innovators find the world stage. With investor skittishness about emerging markets – and often overblown perceptions of risk – Aliança pelo Impacto took a half-dozen fund managers from Brazil on the road. “The global investment community still underestimates the country’s potential,” laments Ricardo Ramos of Aliança, the Brazilian national advisory board for impact investing. “Investor education is one of the most catalytic levers we have to unlock capital flows into the country.” Aliança and ApexBrasil hosted an event at the GIIN Impact Forum in Berlin last month showcasing MOV, which is tackling the high value-added bioeconomy connecting food and health systems through innovation and inclusion. Vox’s new regenerative agriculture fund aims to de-risk the transition to sustainable, zero-deforestation agriculture across the Amazon and Cerrado. Fama Re.Capital is advancing climate, equality and socio-bioeconomy verticals. With COP30 underway in Belém, Brazil’s impact fund managers and other financial innovators are once again on the world stage, this time from home. “The world is looking for where to place its next impact bet,” writes Ramos in a guest post. “What will distinguish Brazil is not only its natural abundance but its capacity to turn that abundance into shared prosperity.”

Navigating COP30. Risk perceptions, amplified by a lack of standardized data and analytical tools, mean capital is getting “stuck,” says Converge Capital’s Marina Cançado. “Private banks or multifamily offices don’t have the time to dedicate to a new topic.” Converge and World Climate Foundation are hosting the World Climate Summit, a COP side event starting today in Belém focused on financial innovations and resources that can “deliver tangible outcomes.” The partners have developed the COP30 Events portal “for people to know and see these countless events and find ways to engage,” says Cançado. More COP30 events.
