Detroit's
Homeownership
Revolution.
Tobias Harris partners with Homium to bring a new path to homeownership to Detroit — no monthly payments, just a fair, sustainable way for families to build equity and stay rooted. This initiative is made possible through the support of generous sponsors and is actively welcoming additional partners.
Lasting change starts with ownership.
Tobias Harris created this initiative to make homeownership a reality for the families powering Detroit's comeback. Designed around shared appreciation financing and tailored to the city's housing dynamics, it gives working families the chance to buy in.
With early support from the Michigan State Housing Development Authority (MSHDA), his former Pistons teammate Jon Leuer, and team owner Tom Gores, Harris is proving that lasting change starts with ownership.

Revolutionary home financing
with no monthly payments.
THHI partners with Homium to offer Shared Appreciation Mortgages (SAMs) — a fair, transparent second-lien loan that adds a silent partner to the traditional mortgage stack. This preferred-equity-style down payment assistance makes homeownership more affordable for working families and aligns incentives for long-term community growth.
Zero Monthly Payments
SAMs eliminate monthly payment burden, allowing families to allocate income toward other financial goals and reducing default risk.
1:1 Shared Growth Model
When homes appreciate, borrowers share the same percentage with THHI as the percentage of the home they borrowed at origination — creating sustainable funding for future families.
Detroit-First Focus
Designed to serve working-class families and individuals, targeting current or former residents of Wayne County earning $45,000+ annually.
Grant and PRI capital that
recycles into the next family.
Homium's tech-driven model uses grant and PRI capital to unlock private mortgage funding for eligible first-time buyers. Our platform tracks results in real time — SAMs issued, homeowners served, and equity built — and keeps costs lower than traditional DPA programs. Every home we finance creates ripples of impact across families, neighborhoods, and generations.

Six dimensions of compounding impact.
Stability and Financial Security
Homeownership reduces housing instability. With no monthly payments, SAMs help families avoid displacement and free up income for savings and essentials.
Health and Wellness
Stable housing improves physical and mental health. Homeowners have control over their living conditions, creating safer and healthier spaces.
Better Educational Outcomes
Kids in owned homes perform better in school and are more likely to graduate. Parents with home equity can invest more in their children's future.
Community Roots
Homeowners build deeper ties to their neighborhoods — attending school meetings, maintaining their homes, and supporting local institutions.
Generational Wealth
SAMs help families build equity. That equity becomes a foundation for future down payments, businesses, and education.
A Self-Sustaining Model
As home values rise, Homium recycles returns into new loans, creating a compounding, long-term engine for equitable homeownership.

The Platform
A fair, no-monthly-payment second-lien loan that helps working families afford homes. Borrowers qualify for conforming first mortgages and avoid PMI.
How it works
Homeowners receive a SAM with no interest, fees, or monthly payments. When they sell or refinance, they repay a fixed share of the home's value.
Why It Matters
Homium lowers the barrier to homeownership while helping families build wealth and stay rooted. Repayments recycle to support more buyers.
Transparent & Impact-Driven
Homium tracks and reports social outcomes, wealth creation, and program performance — giving funders clear insight into their impact.
We're looking for mission-aligned partners.
THHI is welcoming mission-aligned non-profits, social impact investors, foundations, municipalities, governments, and first-mile partners to continue advancing housing affordability in Detroit.
