Housing Purchase Credit (HPC) Clearinghouse System

The Housing Purchase Credit (HPC) Clearinghouse is a proposed financial infrastructure platform that enables renters to build portable homeownership savings through matched contributions from philanthropic funds and participating landlords. Unlike traditional rent-to-own programs, HPCs are escrowed funds (1 HPC = $1) held by regulated custodians and usable only at home purchase closing—preventing speculation while creating real pathways to ownership. All participants can recoup their contributions if the renters opt-out.

Problem Statement

California's affordability crisis has reached critical mass, with renter households unable to accumulate down payments despite stable incomes. The Building a Better California initiative has allocated significant philanthropic capital (targeting over $30bn) specifically for housing solutions. Without immediate infrastructure, this capital will either sit idle or flow into less efficient interventions. The political window for private-led solutions (before government mandates) is narrow.

Target Audience

Primary: Rent-burdened households with stable income (especially $50K-$100K range) who can sustain $300-$500/month savings but lack down payment capital.



Secondary Beneficiaries: Landlords seeking retention incentives and tax advantages; philanthropic funds requiring measurable housing impact; state/local governments seeking private-led affordability solutions.

Potential Impact

Target conversion rate: 40% (vs. <5% for traditional rent-to-own)



Without this solution, renters remain trapped in wealth-extraction cycles, philanthropic capital generates minimal measurable outcomes, and California's homeownership gap widens.

Opportunity

Based on the proposed pilot model (10,000 renters, $4,800 average annual match, 40% conversion rate):

• Annual capital deployment: $48M

• Projected homebuyers: 4,000 over program lifecycle

• Capital recycling: $60M through shared appreciation returns

Sustainable Infrastructure: Shared appreciation recycling creates semi-permanent capital, reducing dependency on continuous philanthropic inflows.



Multi-Stakeholder ROI: Landlords gain tax credits exceeding contributions; lenders access pre-qualified borrowers; government achieves housing goals without budget allocation.



Political Advantage: Solves affordability without forcing existing home price collapse—making it coalition-friendly across property owner and renter constituencies.



Scalability: Once proven in pilot markets (3 cities, 20 landlords, 500 renters), the clearinghouse model can expand statewide with minimal marginal cost.

Stakeholder Obstacles (Challenges)

Renter Barriers: Distrust of predatory rent-to-own schemes, irregular income patterns, fear of losing accumulated credits, and psychological distance from homeownership prevent wealth building.



Landlord Resistance: Property owners lack incentive to subsidize tenant departures and fear administrative burden and regulatory creep.



Capital Inefficiency: Philanthropic housing capital lacks mechanisms for measurable impact, capital recycling, and protection against market distortion.



System Fragmentation: No standardized, transferable credit system exists to coordinate between renters, landlords, lenders, and capital providers.

Risks

Fraud Exposure: Identity fraud, income misrepresentation, and landlord-renter collusion could drain resources.

• Mitigation: KYC/AML protocols, biometric verification, transaction monitoring, severe penalties.



Price Inflation: Demand subsidy without supply controls could bid up home prices.

• Mitigation: Supply-tied match eligibility (new construction/ADUs only) or shared appreciation models (fund receives 25-40% of appreciation on matched portion).



Speculation Risk: HPCs could become tradeable financial instruments.

• Mitigation: No cash redemption, no secondary market, credits expire after 8-10 years unused, redemption only through approved closing agents.



Regulatory Classification: HPC structure could be deemed banking activity.

• Mitigation: Clearinghouse never touches money; regulated custodian holds all funds; statutory safe harbor provisions.



Low Conversion Rates: Enrollment without homeownership outcomes undermines credibility.

• Mitigation: Financial coaching programs, mortgage pre-qualification at 18-24 months, portable credits across properties.
