Selling a Share of Your House to the Bank

At Towerstone, we provide specialist property accountancy services for homeowners, landlords, and property investors. We have written this article to explain what options exist and how they work, helping you make informed decisions.

This is a question that comes up surprisingly often, usually from homeowners who are asset rich but cash poor. They may own a valuable property outright or with a small mortgage but need access to money without wanting to move. Selling half the house to a bank feels like a logical idea, almost like cashing in part of the value while staying put.

In the UK, the short answer is no, you cannot simply sell half your house to a bank in the way many people imagine. Banks do not buy equity in residential homes in the same way that investors buy shares in a company. However, there are arrangements that achieve a similar outcome in practice, and understanding the differences is essential before making any decisions.

In this article, I will explain clearly what selling half your house to the bank would actually mean, why banks do not do this directly, and what realistic alternatives exist in the UK. This is written in plain UK English and reflects how lenders, solicitors, and HMRC actually treat these arrangements.

Why banks do not buy part of your house outright

Banks are lenders, not property investors. Their business model is based on lending money secured against property, not owning pieces of residential homes.

If a bank were to buy half your house, it would:

• Own part of a residential property

• Take on property market risk

• Become involved in maintenance and sale decisions

• Have to share future gains and losses

This creates complexity and risk that banks are not set up to manage. They prefer predictable interest income rather than exposure to house price movements.

Because of this, UK banks do not offer a product where they buy a percentage of your home in exchange for cash.

What people usually mean when they ask this question

When someone asks whether they can sell half their house to the bank, they are usually looking for one of the following outcomes:

• Accessing cash tied up in their home

• Reducing monthly outgoings

• Avoiding moving house

• Sharing future property value risk

• Raising money without taking on a traditional mortgage

While selling half the house is not an option, there are products and arrangements that achieve some of these goals.

Equity release and lifetime mortgages

The closest mainstream option is equity release, specifically a lifetime mortgage.

A lifetime mortgage allows homeowners, usually over a certain age, to borrow against the value of their home. The loan is secured on the property and repaid when the home is sold, typically after death or moving into long term care.

You do not sell part of your house. You retain full ownership, but the lender has a charge over the property.

Key features include:

• No monthly repayments required in most cases

• Interest rolls up over time

• The loan plus interest is repaid from the sale of the property

• Any remaining value goes to you or your estate

While this can feel like selling part of the house, legally it is still borrowing.

Home reversion schemes and selling a share

Another equity release option is a home reversion plan.

This is the closest thing to selling part of your house, but it is still not the same as selling to a bank.

Under a home reversion scheme:

• You sell a percentage of your home to a provider

• You receive a lump sum or regular payments

• You retain the right to live in the home rent free

• The provider receives their share when the property is sold

These schemes are offered by specialist providers, not high street banks.

It is important to understand that the amount you receive is usually significantly less than the market value of the share sold. This reflects the fact that the provider may wait many years to realise their investment.

Why home reversion plans are used cautiously

Home reversion plans can be appropriate in some situations, but they come with trade offs.

Common issues include:

• Selling a share at a substantial discount

• Reduced inheritance for beneficiaries

• Limited flexibility once entered into

• Fewer providers and less competition than mortgages

Because of these factors, they require careful advice and are not suitable for everyone.

Shared ownership is not the same thing

Some people confuse selling half their house with shared ownership.

Shared ownership schemes usually apply when buying a property, not when you already own one outright. They involve purchasing a share of a property and paying rent on the remainder.

You cannot usually convert an existing home into a shared ownership arrangement with a bank or housing association.

Can I sell half my house to a private investor

In theory, yes, but in practice this is rare and risky.

You could sell a share of your home to a private individual or investment company. This would make them a co owner of the property.

However, this raises serious practical and legal issues, including:

• Disagreements over maintenance

• Disputes about when to sell

• Complex exit arrangements

• Mortgage restrictions

• Loss of control over your home

Most lenders do not allow this where a mortgage exists, and most homeowners are uncomfortable with sharing ownership of their primary residence.

Why mortgages are still the most common solution

For most people looking to release value from their home, a traditional mortgage or remortgage remains the simplest and cheapest option.

This involves borrowing against the property while retaining full ownership.

Advantages include:

• Clear legal structure

• Competitive interest rates

• Full control over the property

• Flexibility to repay or refinance

The downside is the need to make monthly repayments, which may not suit everyone.

What about selling part of the house and renting it back

Another idea people raise is selling part of the house and paying rent on it.

This is not something banks offer, but it does exist in limited forms through sale and rent back schemes.

These involve selling the entire property to a company and then renting it back as a tenant.

These schemes are heavily regulated due to past abuses and are not the same as selling half the house.

Tax implications of selling part of your home

If you do sell a share of your home, whether through a home reversion plan or to a private party, there can be tax consequences.

These may include:

• Capital Gains Tax if the property is not fully covered by main residence relief

• Stamp duty considerations for the buyer

• Inheritance tax implications

• Loss of future tax reliefs

Tax should always be considered before entering into any equity sharing arrangement.

Why professional advice is essential

Arrangements that feel simple on the surface often have long term consequences.

Before proceeding with any plan that involves giving up a share of your home, you should take:

• Independent legal advice

• Regulated financial advice

• Tax advice where relevant

This is particularly important because many equity based products cannot be undone easily once entered into.

A realistic way to think about this question

Rather than asking can I sell half my house to the bank, the more useful question is what is the best way to release value from my home given my age income and long term plans.

For some, that will be a remortgage.
For others, equity release may be appropriate.
For a smaller group, downsizing or selling and moving may still be the most efficient option.

There is no one size fits all answer.

Common misconceptions worth clearing up

A few myths are worth addressing clearly.

Banks do not buy shares in houses.
Selling half your house does not remove all financial risk.
Equity release is not free money.
Giving up ownership always affects future flexibility.

Understanding these points helps avoid disappointment later.

Final thoughts from real world experience

So, can you sell half your house to the bank in the UK. No, not directly. Banks do not buy equity in homes. What you can do is borrow against your home or enter into specialist arrangements that share future value in exchange for cash today.

In my experience, people who explore these options carefully and with proper advice are far more likely to be satisfied with the outcome than those who rush in based on a simple idea of selling part of the house.

Your home is usually your largest asset. Any decision to give up part of it, in ownership or value, should be made with a clear understanding of the long term consequences, not just the short term cash benefit.
