Can I Sell My House to My Son

Discover the legal and tax rules when selling your house to your son in the UK, whether at full price or as a family discount.

Can I Sell My House to My Son

Selling your home to your son might seem like a simple and heartfelt gesture, particularly if you want to help them onto the property ladder or keep a cherished family home within the family. In the UK, there is no law preventing you from selling your house to your child, but the process must be handled properly to ensure that it is legally sound, financially transparent and compliant with tax regulations.

Whether you intend to sell the property at full market value, below market value or as part of an inheritance strategy, it is important to understand the implications. While family sales are perfectly legal, they attract closer scrutiny from lenders, solicitors and HMRC. Approaching the sale with proper advice and full awareness of the potential risks and responsibilities will help protect both parties and avoid complications in the future.

Selling at Full Market Value

If you choose to sell your house to your son at the full market value, the process is relatively straightforward. The sale will follow the usual legal and conveyancing procedures. Your son will need to obtain a mortgage or have sufficient funds in place, just as he would if buying a property from an unrelated seller.

You will need to instruct a solicitor to act for you, and your son must have separate legal representation to avoid any conflict of interest. The property will be valued by an estate agent or RICS surveyor, and a formal offer will be made. A mortgage lender will likely require their own valuation before approving any loan.

Selling at full market value ensures transparency and reduces the likelihood of complications with mortgage providers or tax authorities. It also means the transaction is treated like any other house sale, with standard legal and tax processes applying.

Selling Below Market Value

Many parents consider selling their home to their son at a discounted price as a way of helping them financially. While this is legal, it introduces added layers of complexity, particularly in relation to mortgage lending and tax liabilities.

If you choose to sell the property at a price lower than the current market value, the difference between the sale price and the market value is considered a gift. This is known as a transfer at undervalue. While this can be an effective way of passing on wealth during your lifetime, it may be subject to inheritance tax if you pass away within seven years of the gift, and the total value of your estate exceeds the inheritance tax threshold.

Most mortgage lenders will want to be informed of the discount and may require additional documentation to assess the true value of the transaction. They will also want to ensure that the arrangement is not being used to hide debt, influence benefits or avoid future care costs.

Solicitors on both sides will need to confirm that the buyer is not being pressured and that the seller understands the consequences of transferring equity. The transaction will still be subject to standard legal checks, including title deeds, searches and Land Registry updates.

Tax and Legal Considerations

When selling your house to your son, there are several tax implications to keep in mind. If the property is your main residence, you are generally exempt from Capital Gains Tax. However, if the property is a second home or buy to let, you may need to pay Capital Gains Tax based on the difference between the original purchase price and the sale value.

As mentioned earlier, if you sell below market value and pass on a financial gift, the transaction may be considered a Potentially Exempt Transfer by HMRC. If you pass away within seven years, the gifted portion may be added back into your estate for inheritance tax purposes.

It is important to record the true market value and the discounted sale price to ensure transparency. Any significant gifts should be documented clearly, and you should consider speaking to a tax adviser or estate planner to explore the most effective approach for your circumstances.

You may also want to update your will and any financial arrangements to reflect the sale. If other family members are involved, or if there are concerns about fairness or future disputes, legal advice and formal documentation can help avoid misunderstandings later on.

Mortgage and Affordability

If your son is buying the house with a mortgage, the lender will need to be informed that this is a related party transaction. Some lenders are more cautious about lending in family sales, particularly where the property is being sold below market value. They may require higher deposits or apply stricter lending criteria.

That said, some mortgage lenders offer specific products for family transactions and will allow a gifted deposit to be factored into the application. If you are gifting part of the property value as a deposit, you will usually need to complete a formal gifted deposit declaration confirming that the gift is non repayable and that you will have no legal interest in the property after the sale.

An independent mortgage broker can help identify lenders willing to support family transactions and assist with the application process.

Alternatives to Selling

If your goal is to help your son without immediately selling the house, there are other routes to consider. You might gift a share of the property through a Transfer of Equity or allow him to live in the property under a tenancy agreement. Alternatively, you could place the property in a trust as part of an estate planning strategy.

Each of these options has different legal, financial and tax consequences, so it is worth speaking to a solicitor and financial adviser to explore the best solution for your family.

Selling your house to your son can be a rewarding and generous decision, but it must be handled with care. The right preparation, advice and professional support will help ensure that the transaction is legal, transparent and beneficial to all involved.
