Building Society Cohousing Mortgages: How to Finance a Home in a UK Cohousing Community
Buying a home in a cohousing community can be different from purchasing an ordinary house or flat. Your home may be privately owned, but shared gardens, common buildings, resident agreements and restrictions on selling can affect whether a mortgage lender accepts the property.
The useful news is that Ecology Building Society has a dedicated Community Living Mortgage for individuals buying homes within qualifying cohousing developments. It also offers separate lending for community-led housing organisations, cohousing groups and housing co-operatives.
This guide explains both mortgage routes, their eligibility requirements, ownership structures, deposits, legal checks, costs and the practical steps to take before committing to a cohousing purchase or development.

UK Cohousing Mortgages: Quick Answers
What Is Cohousing in the UK?
Cohousing is a form of community-led housing where people have private homes while sharing selected facilities and responsibility for managing their neighbourhood.
Residents normally have their own front door, kitchen, living space and personal privacy. Shared facilities might include a communal garden, common house, guest rooms, workspace, laundry area or meeting room.
Each household occupies its own self-contained dwelling rather than sharing all living accommodation.
Residents may jointly use and maintain common buildings, gardens and other communal facilities.
Community decisions are commonly made through an agreed resident-led governance structure.
Homes may be individually owned, held on leasehold arrangements or structured through a housing co-operative or other community organisation.
The UK Cohousing Network describes cohousing as a balance between privacy and community, with self-contained homes alongside facilities that encourage connection and mutual support.
That distinction matters to mortgage lenders. A self-contained home with acceptable title may be suitable for an individual mortgage, while a property owned collectively by an organisation may require a different lending arrangement.

After opening this link:
- Read the explanation of private homes and shared community facilities.
- Review the role residents play in community management and decision-making.
- Identify whether the community you are considering follows a similar model.
- Ask the community organiser how private homes and shared spaces are legally owned.
- Use that ownership information when discussing mortgage eligibility with a lender.
How Cohousing Ownership Affects Mortgage Eligibility
The first question is not which lender has the lowest rate. It is what exactly you will own and what security the lender can take.
Two developments can both call themselves cohousing while using very different legal arrangements.
Ecology Building Society Community Living Mortgage for Individual Buyers
Ecology Building Society offers a specific Community Living Mortgage designed for individuals buying a home in a qualifying cohousing community.
This is particularly relevant because some ordinary mortgage lenders may be uncomfortable with unusual leases, shared facilities, community rules or non-standard construction.
Published Community Living Mortgage Criteria
90% of the eligible property value or purchase price, subject to assessment.
75%, subject to interest-only eligibility and an acceptable repayment strategy.
£750,000 under the currently published individual Community Living product.
35 years, subject to the borrower’s circumstances.
C or higher, with a predicted energy assessment considered for qualifying new-build developments.
Leasehold may be considered, provided the cohousing lease satisfies Ecology’s criteria.
Some non-standard construction types can be accepted following suitability, insurance and valuation checks.
Available for eligible properties across the UK.

This is the principal official route for an individual who wants to buy or remortgage a qualifying cohousing home.
After opening this link:
- Read the Community Living Mortgage overview to confirm that you are seeking an individual home mortgage rather than development finance.

Mortgages for Cohousing Groups, Co-operatives and Community-Led Developments
If your organisation is buying land, constructing homes or borrowing against a property held collectively, an individual residential mortgage may not be appropriate.
Ecology has a separate community-led housing lending service designed for qualifying housing co-operatives, cohousing groups, community land trusts and housing associations.
Ecology publishes lending up to 75% LTV for eligible cohousing groups, subject to assessment.
Eligible co-operative projects may obtain loans up to 75% LTV under Ecology’s published community criteria.
Qualifying community land trusts may be considered for borrowing up to 80% LTV.
Ecology publishes an 80% maximum LTV for qualifying housing associations.
Stage-release funding can be available for eligible construction or renovation projects.
Ecology publishes community-led lending terms up to 35 years, depending on the project.

What a Cohousing Group Should Establish Before Seeking Finance
How Much Deposit Do You Need for a Cohousing Mortgage?
The deposit depends on whether you are an individual buying a qualifying home or an organisation borrowing to develop property.
Example 1: Buying Your Own Cohousing Home
Suppose an eligible cohousing property costs £300,000.
A £270,000 mortgage represents 90% LTV. That is within Ecology’s published repayment LTV ceiling for its Community Living product.
However, your actual borrowing may be lower because of affordability, valuation, property criteria or other underwriting conditions.
Illustrative figures, not a mortgage approval or current lending quotation.
Example 2: A Cohousing Organisation Financing Property
Suppose a cohousing organisation owns or proposes to acquire qualifying property valued at £1,000,000.
For an eligible cohousing group, the published 75% LTV limit would suggest a maximum of £750,000 against that assumed value.
Actual lending could be lower, and the organisation may need additional funds for construction, professional fees, contingency and costs not reflected in the security valuation.
This is an LTV illustration only. It is not a development funding commitment. Lenders may use their own valuation and project-cost assessments.
Ecology Cohousing Mortgage Rates, Fees and Repayment Costs
Ecology currently publishes a variable-rate Community Living Mortgage for individual borrowers. Mortgage rates can change, so a dated product snapshot should never replace a current personal illustration.
Published Product Snapshot
Ecology currently lists no Early Repayment Charge on this product, which may provide flexibility for borrowers who want to overpay or repay their mortgage earlier.
Other charges, such as valuation costs, may still apply. Review the lender’s current tariff and personalised mortgage illustration.
What the Representative Example Means
Ecology’s official product page currently illustrates a £225,000 mortgage over 30 years and shows how the variable interest rate, repayment schedule and fees affect the total amount repayable.
For an accurate comparison, ask the lender for a mortgage illustration using your own deposit, property value, income and proposed term.
Other Costs of Living in Cohousing
Legal Checks Before Buying a Cohousing Property
Legal documents are especially important in cohousing because the lender must be satisfied that it can enforce its security and that the property remains marketable if the borrower defaults.
The UK Cohousing Network’s guidance for individuals highlights the need to examine title restrictions, lease covenants, remaining lease length and whether mortgage lenders will accept the ownership arrangement.
Ask Your Conveyancer to Review These Issues
Confirm exactly which legal interest you are buying and who owns the land or shared buildings.
Check how many years remain and whether the term satisfies the proposed lender’s requirements.
Review whether future buyers must be approved by the community or meet particular criteria.
Ask whether the lease adequately protects the lender if repossession or a mortgagee sale becomes necessary.
Understand how regular and exceptional communal costs are calculated and collected.
Review any contractual requirements concerning resident participation, shared responsibilities and dispute resolution.
Check whether you can rent out the property if your circumstances change and whether lender consent is required.
Confirm the valuer and lender accept all restrictions affecting the property, including any affordable-housing provisions.
UK Cohousing NetworkCohousing for Individuals: UK Cohousing Network Guidance (PDF)
After opening this link:
- Find the sections dealing with legal title, lease terms and covenants.
- Review the questions concerning restrictions on the property’s ownership and use.
- Check the discussion about whether lenders will accept the lease.
- Review the potential implications for selling the property in the future.
- Take the relevant questions to a conveyancer experienced in community-led housing.
- Ask the proposed mortgage lender to review the actual property documentation rather than assuming that general cohousing eligibility is enough.
EPC, Non-Standard Construction and New-Build Requirements
Community-led housing schemes often place particular emphasis on energy efficiency, sustainable design and lower environmental impact.
Ecology’s Community Living Mortgage is designed partly around this market, but its environmental eligibility requirements still apply.
Ecology currently requires a minimum EPC rating of C or higher for this specific product.
A predicted energy assessment can be provided where the home is still being developed.
Qualifying recently built properties must have acceptable warranty or certification evidence.
Ecology considers certain construction methods, provided they meet its requirements and can be insured and valued satisfactorily.
Buildings insurance must be available and acceptable under the lender’s criteria.
The property must satisfy the lender’s condition, security and marketability assessment.
What if the Cohousing Home Has an EPC Below C?
Under Ecology’s currently published Community Living criteria, a property below the minimum EPC requirement would not qualify on the stated terms.
Ask Ecology whether another product route or a qualifying improvement project could be considered. Do not budget for approval or an environmental discount without a lender assessment.
Can You Afford a Cohousing Mortgage?
The affordability assessment considers the proposed mortgage alongside the household’s income, other debts, essential costs and housing commitments.
For cohousing, the shared community’s regular charges and any required member contributions can be particularly important.
Illustrative Monthly Housing Budget
This example shows why a mortgage repayment should not be assessed in isolation. A household paying £1,250 for the loan may actually need to budget considerably more for its total housing costs.
Illustrative amounts only. Real charges vary by scheme and location. Additional household expenditure, insurance and other costs are not included.
What the Lender Will Assess
How to Apply for a UK Building Society Cohousing Mortgage
The application route depends on whether you are an individual buying a home or a community organisation seeking project finance.
For an Individual Homebuyer
- Identify the property. Obtain the development name, property address, purchase price and proposed tenure.
- Ask for the legal documents. Request the draft lease or freehold title details, community agreement and relevant service-charge information.
- Check the environmental criteria. Obtain the EPC or predicted energy assessment and any required new-build warranty documents.
- Calculate your deposit. Check the current maximum LTV and the amount of borrowing your household can support.
- Contact Ecology. Explain that you are purchasing an individual cohousing home and ask whether the proposed scheme fits its Community Living criteria.
- Complete the affordability stage. Provide income, household expenditure and borrowing information for an initial assessment.
- Submit the full application. Supply the property’s details and any additional documents required by underwriting.
- Arrange specialist conveyancing. Ensure the solicitor or conveyancer understands the cohousing lease and the mortgage lender’s requirements.
- Review the formal offer. Check the interest rate, APRC, mortgage term, fees, conditions and obligations attached to the shared property.
- Complete only when ready. Ensure the lender, conveyancer and community organiser have satisfied all necessary legal and financial conditions.
For a Cohousing Organisation
- Establish the borrowing entity. Confirm the legal structure and authority to borrow.
- Prepare the project plan. Include the land arrangement, planning position, accommodation schedule and resident ownership model.
- Prepare a detailed budget. Include construction costs, professional fees, contingency and cash-flow projections.
- Confirm funding contributions. Document committed member equity, grants and other sources of capital.
- Approach Ecology’s community lending team. Explain the proposed security, funding purpose and project stage.
- Discuss valuation and loan structure. Establish whether staged funding or other tailored terms may be appropriate.
- Complete the lender’s assessment. Provide governance, project, financial and legal evidence requested.
- Obtain professional advice. Engage suitable legal, financial and construction professionals before accepting financing commitments.
Documents Needed for a Cohousing Mortgage Application
Individual buyers and community organisations normally need different evidence. Ask the lender for a case-specific list.

Cohousing vs Shared Ownership: Which Mortgage Do You Need?
Cohousing schemes can include individually owned homes, but some also use shared ownership or other affordable-housing mechanisms.
The right mortgage follows the actual legal structure, not the marketing description.
Official England scheme guidanceGOV.UK: How Shared Ownership Works
After opening this link:
- Read how buying a share and paying rent on the remaining interest works.
- Check the current shared ownership eligibility and deposit provisions.
- Review the separate costs, service charges and leasehold responsibilities.
- Check the rules for buying additional shares and selling the property.
- Confirm whether your proposed cohousing home actually falls under the shared ownership scheme.
This GOV.UK shared ownership scheme guidance applies to England. Scotland, Wales and Northern Ireland have different housing scheme arrangements.
Can You Sell or Remortgage a Cohousing Property Later?
Potentially, but resale and remortgaging are two of the most important issues to investigate before buying.
Some cohousing communities have rules intended to preserve their character, resident participation or affordability. Depending on how these are legally structured, they may affect the pool of buyers and the lender’s assessment of marketability.
Check whether the community has a formal role in approving or nominating a purchaser.
Review any resale price cap or formula that limits the amount you can receive.
Determine how restrictions operate if a lender needs to enforce its security.
Some lenders may refuse the type of lease or title even where a specialist lender currently accepts it.
Ecology currently allows qualifying Community Living remortgages, but a fresh affordability and property assessment still applies.
Check whether unpaid charges, repairs or collective obligations can affect the property or its resale.
Common Cohousing Mortgage Problems and How to Avoid Them
An individual homebuyer and a development organisation require different underwriting and often different mortgage products.
Get an early review of the proposed lease and title documents before paying significant non-refundable costs.
Check Ecology’s minimum EPC requirement before relying on its Community Living product.
Obtain a written budget showing recurring charges and possible major maintenance contributions.
Do not apply the individual 90% LTV limit to group borrowing or construction finance.
Ask your conveyancer whether restrictions could reduce the number of eligible purchasers or affect valuation.
For construction projects, budget for delays, cost increases and timing differences in stage payments.
Variable-rate borrowing can increase monthly repayments. Consider whether your household or organisation could withstand a higher rate.

5. Can I mortgage a leasehold cohousing property?
Potentially. Ecology states that its Community Living Mortgage can consider eligible leasehold property, but the cohousing lease must satisfy its requirements. The lender and conveyancer must be satisfied with the title, restrictions and security.
6. Does a cohousing property need an EPC rating of C?
Ecology’s current Community Living Mortgage requires an EPC rating of C or higher. For a qualifying new-build property still in development, an acceptable predicted energy assessment can be provided, subject to the lender’s criteria.

8. Is cohousing the same as shared ownership?
No. Cohousing is a community-led housing arrangement involving private homes and shared spaces. Shared ownership is a specific tenure under which a buyer purchases a share and usually pays rent on the remaining share. Some cohousing developments may use shared ownership, but not all do.
9. Can I sell or remortgage a cohousing home?
Potentially. Your ability to sell or remortgage depends on the property’s ownership, lease, resale restrictions and lender requirements. Ecology currently considers eligible Community Living remortgages, but approval is not automatic.
10. What should I check before applying for a cohousing mortgage?
Confirm the ownership structure, lease and title restrictions, EPC, property valuation, community charges, deposit, income requirements and lender acceptance. Use a conveyancer experienced with unusual property tenure and obtain a personalised mortgage illustration before committing.
