Shared funding for affordable homes

The housing problem

A home needs to be affordable to live in, not only affordable to finance. Rent, service charges and energy bills compete with food, transport and other household needs. An insecure tenancy or an unaffordable repair can undermine a household even when the advertised rent looks lower than nearby alternatives.

The European housing data on this website measures housing-cost overburden, not everyone who cannot find a suitable home. It also cannot tell us which homes a local community needs. We use the sourced housing data and its methodology as context, then need local evidence on incomes, housing conditions and access.

Housing finance must bridge large upfront purchase or construction costs and the income received over a home’s life. The 2026 finance review distinguishes that capital funding from revenue for management, maintenance and upgrades. Raising purchase money alone does not fund a lasting housing service. [1]

A funding platform cannot resolve every shortage, land constraint or household income gap. Policy research treats finance, land, governance and energy standards as connected tools rather than one universal blueprint. [3] Fair Squares focuses on the funding and decision-making part, working alongside the organisations responsible for housing.

What Fair Squares is

Fair Squares is developing a community-funded housing model. Eligible members pool capital, review housing proposals and participate in funding decisions. The aim is to support affordable homes while limiting the rental return expected by capital providers.

Members participate in a fund rather than buy a piece of legal title to a particular home. A housing provider would manage homes and tenancies. Residents’ rights must come from enforceable housing agreements, not depend on buying investment shares.

The prototype on Aztec demonstrates deposits, fund records, reviewed proposals, member votes and rental-income mechanics. Aztec is a blockchain designed to support private computations and records. The software is one part of the model; legal ownership, property management and resident protections require separate arrangements.

The commitments behind the model

We want to connect the fund’s financial terms to a housing purpose. A pilot should put these commitments into agreements and measure whether they hold:

• Affordability: Aim for rents at least 20% below a credible local market comparison, then check total housing costs against household incomes
• Limited return: Use an annual rental-return target of around 3%, without promising a guaranteed or net investor yield
• Secure homes: Agree tenancy terms, repair responsibilities and rent-review rules before residents move in
• Shared responsibility: Give fund members a defined role in funding decisions and establish a separate, meaningful role for residents
• Long-term care: Pay for management, maintenance and future upgrades rather than leave those costs unresolved

These commitments guide the proposed model. They are not evidence that Fair Squares has already achieved permanent affordability, resident ownership or a completed housing programme.

Affordability for households

A discount to market rent and affordability for a household answer different questions. A home can be below market and still cost more than a resident can pay. A pilot needs both a defensible local rent comparison and a household-budget assessment.

Compare like-for-like homes by location, size, condition and tenancy terms. Record the date and source of the comparison, and distinguish advertised rents from agreed rents. Include service charges and expected energy costs when assessing a resident’s budget. Do not treat the statistical overburden threshold as a recommended rent or a promise of comfort below that threshold.

The prototype’s expected rent is linked to acquisition value. At the illustrative 3% annual parameter, a €275,000 home produces €687 monthly rent after whole-euro flooring. Against an assumed €1,000 monthly comparison, that is 31.3% lower. Against €600, it is higher and fails the 20% reduction goal. These are arithmetic examples, not observed city rents.

If a home fails the affordability check, the model needs a different purchase price, funding arrangement or property. It cannot force a favourable result by changing the comparison. If household support is necessary, eligibility and continuing availability must be verified rather than assumed.

Funding homes and paying for upkeep

The funding plan needs two budgets: one to acquire a home and another to operate it. A target return is not a complete budget. The finance review also warns that recovering costs through rent can exclude lower-income households; covering costs and keeping homes accessible must be tested together. [1]

The website’s funding calculator estimates acquisition-linked gross rent. It does not deduct those costs or establish the amount available to investors after them. Cash not used to acquire homes earns no rental income in that scenario. The around-3% figure must not be read as a net return on all contributed capital.

A pilot may assess member capital alongside provider resources, grants, public land arrangements or other permitted financing. Each source needs documented terms, eligibility, cost and duration. No public subsidy, guarantee or preferential land agreement is secured by the prototype.

Reserves and reinvestment also need explicit rules: who contributes, who decides, what the money pays for and what happens when income falls short. Fair Squares is not an established revolving fund simply because members can reinvest. A lasting replenishment commitment would need to be designed and funded.

Land, ownership and secure tenancies

The home’s legal and land arrangements shape what the fund can achieve. The 2026 land review describes different approaches, including public leasing and land trusts, and stresses their local context. [2] These are possible arrangements to assess with partners, not features Fair Squares already operates.

Before funding, establish who owns the land and building, who can grant a tenancy, and which restrictions survive a sale or refinancing. An affordability commitment must specify its duration, enforcement and remedies. A digital rent ceiling alone cannot stop an unlawful eviction or bind a future owner outside the agreed legal structure.

Residents need understandable allocation criteria, tenancy terms and a route to resolve complaints. The pilot should define rent reviews, maintenance standards and protections if the provider or fund encounters financial difficulty. Any path to individual ownership would need separate legal and financial terms; buying fund shares does not create that right.

From a proposal to a managed home

The funding decision sits between local preparation and ongoing housing management. The proposed sequence is:

1. Define the housing need. Residents, providers and local partners identify who needs a home, where and on what terms.
2. Prepare the property dossier. Establish valuation, ownership, building condition, energy performance, required works and the full operating budget.
3. Review the proposal. The housing council assesses the proposal before an eligible-member funding vote. A recorded approval is not a substitute for professional due diligence.
4. Agree the legal terms and fund. Confirm contracts, affordability conditions and available capital before committing money.
5. Allocate and manage the homes. The provider applies the agreed access rules, manages tenancies and handles repairs and resident concerns.
6. Report and review. Compare actual costs, rents and conditions with the proposal; investigate shortfalls and revise future decisions.

The prototype demonstrates parts of review, voting and fund accounting. The property inspections, tenancy agreements and housing-management work must happen outside the software. The funding process and technical walkthrough explain the current interface.

Decisions and accountability

A funding vote and a resident’s say in their home are not interchangeable. The prototype checks eligibility for member votes and supports council review. A pilot must define who appoints reviewers, manages conflicts of interest and holds decision-makers accountable.

Residents should help define housing standards and the decisions that affect their lives. Their tenancy rights must not depend on having capital to invest. The pilot needs clear routes for resident representation, complaints and escalation, alongside the fund’s member rules.

Publish the proposal’s assumptions, review criteria, approved funding terms and aggregate outcomes without exposing residents’ personal information. Define who can change parameters, pause operations or respond to an emergency. Participation rewards are separate from rental income and cannot stand in for evidence of housing benefit.

Privacy and verifiable records

Members and residents should not have to make personal finances public to participate. The design explores proving eligibility and selected fund actions without publishing every underlying record. Verification should answer a defined question, not collect information because the technology allows it.

Privacy is not the same as secrecy about how the fund operates. Partners still need reliable accounts, controlled access for authorised checks and a way to resolve errors. Legal duties around identity, record retention and personal data remain.

The current demo uses server-managed test accounts, and the protocol still has public records and known transaction-linkage risks. It is not a guarantee of anonymity or an untraceable ballot. A production design needs an independent security and privacy review, a custody model and clear responsibility for sensitive information.

Risks and member exits

Housing is a long-lived asset; members may need their money sooner. The fund must explain that mismatch before accepting real capital. A recorded balance or a share-transfer feature does not guarantee a buyer, a redemption date or an unchanged price.

• Property and operating risk: Vacancies, arrears, repairs and valuation changes can reduce income or capital value
• Liquidity risk: Withdrawals depend on available capital and the agreed rules; selling homes to meet exits may conflict with residents’ security
• Funding risk: Grants, land arrangements or other support can expire or fail to materialise
• Technology and custody risk: Contract defects, key loss or service failures can prevent access or compromise records
• Legal and governance risk: The chosen structure must address applicable fund, tenancy, tax and data rules, including disputes and insolvency

Before a pilot, define exit terms, valuation methods, shortfall procedures and how resident protections continue during a transfer or wind-down. Stress-test lower rental income and higher costs. A capped target return limits expectations; it does not remove investment risk or guarantee the social outcome.

Measuring the pilot

Measure the homes and household outcomes, not only the money raised or votes cast. Record a baseline before funding and agree who checks the results. A pilot should track:

• Household affordability: Rent, charges and energy costs relative to income, with the local comparison and its limitations
• Access and security: Who receives a home, whose needs remain unmet, tenancy stability and the handling of complaints
• Housing quality: Condition, repair response, energy performance and the resident’s experience
• Financial durability: Actual operating costs, vacancies, rental income, reserves and the difference between target and realised return
• Participation: Who has a voice, which decisions residents can influence and how conflicts are resolved

Report what did not work as well as what did. Without a suitable comparison, describe observed changes rather than claim the fund caused them. Keep personal household data protected and publish enough aggregate evidence to assess the model.

The work before a pilot

Our next step is a local housing proposal with partners who can take responsibility for delivery. That work needs a defined resident group, a suitable property or portfolio, an accountable provider and a legal structure connecting the fund to the homes.

Before real money is accepted, agree the complete budget, affordability test, tenancy protections, governance and exit rules. Complete the necessary regulatory, security and privacy reviews. Publish the decision to proceed, revise or stop against those criteria.

Residents, housing providers and municipalities can contact the team about shaping a pilot. Prospective members can explore the demo to understand the funding flow, without treating it as an investment offer.

What success would mean

Success is a home a household can afford and keep, maintained by a provider with the resources to care for it. The fund should make its contribution and risks understandable, while giving residents and members a defined say.

Fair Squares proposes shared funding with limited rental returns as one way to support that goal. A local pilot must show whether the financial terms, legal protections and day-to-day management work together. The software is ready to be examined; the housing outcome still needs to be demonstrated.
