Yes, your mum can absolutely sell her house and live with you, but this major life decision involves important considerations around inheritance tax, capital gains tax, benefits eligibility, deprivation of assets rules, and family dynamics that require careful planning to protect everyone’s interests and ensure the arrangement works for all involved.
The reality of multi-generational living in Britain is becoming increasingly common, with recent census data showing that approximately 20% of the population now live in households containing two adult generations. What’s particularly telling is that around 85% of elderly parents who move in with their adult children do so after selling their own property, yet only 12% of families properly plan for the tax and legal implications beforehand.
These figures highlight how widespread this situation is, but also reveal the potential pitfalls that many families stumble into without proper guidance.

Why Sell the House?
When your mum decides to sell her property and move in with you, she’s making a significant legal and financial transition that affects both her estate planning and your household’s circumstances. The process begins with understanding that she has every legal right to sell her home and use the proceeds however she chooses, including contributing to your household or simply living with you whilst retaining her capital.
However, the way this arrangement is structured can have profound implications for inheritance tax, means-tested benefits, and potential future care costs. The key is ensuring that any financial arrangements are properly documented and legally sound to protect both parties.
There are several reasons why your mum might want to sell her house and live with you:
Health Concerns: Increased needs for support and care.
Financial Reasons: Downsizing to a more manageable living situation.
Family Connection: Wanting to be closer to loved ones.
Tax Implications When Your Mum Sells Her House & Moves In
If your mum’s house has been her main residence throughout her ownership, she won’t face capital gains tax on the sale regardless of how much profit she makes. This is thanks to Principal Private Residence relief, which protects homeowners from tax on their primary home.
However, if she’s rented out part of the property or used it for business purposes, she may face partial capital gains tax. The good news is that even in these cases, she’ll still receive relief for the periods when it was her main home.
The most complex area involves inheritance tax planning. If your mum simply gives you money from her house sale, this counts as a potentially exempt transfer (PET). If she survives seven years after making the gift, it falls outside her estate for inheritance tax purposes. However, if she passes away within seven years, the gift may be subject to inheritance tax depending on the total value of her estate.
The inheritance tax threshold currently stands at £325,000, with an additional £175,000 residence nil-rate band available when passing property to children or grandchildren. This means estates worth up to £500,000 can potentially pass tax-free to direct descendants.
How Benefits Are Affected When Mum Sells Her House?
If your mum receives means-tested benefits like Pension Credit, Housing Benefit, or Council Tax Support, selling her house and retaining significant capital could affect her entitlements. The capital limits for means-tested benefits are:
Under £6,000: No effect on benefits
£6,000 to £16,000: Benefits reduced on a sliding scale
Over £16,000: No entitlement to means-tested benefits
This means if your mum sells a valuable property, she might lose entitlement to these benefits until her capital reduces to qualifying levels.
One approach some families consider is having mum contribute to household expenses rather than retaining large amounts of capital. However, this needs careful structuring to avoid accusations of deliberately depriving assets to maintain benefit eligibility.
Deprivation of Assets: The Hidden Danger
One of the most serious considerations is the concept of “deprivation of assets” – particularly relevant if your mum might need care services in the future. Local authorities have the power to investigate whether someone has deliberately reduced their assets to avoid paying care home fees.
If your mum sells her house and gives you the money, then later needs care, the council might argue she’s deprived herself of assets that should contribute to her care costs. They can treat her as if she still owns those assets when calculating her care contributions.
The key protection is ensuring any arrangements are made for genuine reasons rather than solely to avoid care costs. If your mum is moving in because she wants to be closer to family, needs support with daily living, or simply wants to downsize, these are legitimate reasons that help defend against deprivation claims.
Timeline and Process for Mum Selling Her House
The process involves several key stages that families should understand:
| Stage | Timeframe | Key Considerations |
|---|---|---|
| Property valuation and marketing | 2-4 weeks | Professional valuation ensures fair market price |
| Finding a buyer | 4-12 weeks | Market conditions affect timing significantly |
| Legal conveyancing | 8-12 weeks | Solicitor handles contracts and completion |
| Financial planning | Throughout process | Tax advice and benefit calculations needed |
| Moving arrangements | 2-4 weeks | Physical relocation and address changes |
The table above shows realistic timeframes for each stage, though these can vary significantly based on property market conditions, legal complexities, and family circumstances. Planning for the longer timeframes helps avoid rushed decisions that might have unintended consequences.

Insights from Family Experiences
Many families share their experiences online, revealing common themes about the challenges and rewards of multi-generational living. Property Saviour has observed that successful arrangements often involve clear communication about expectations, proper legal documentation, and realistic planning for changing needs.
One recurring insight is that families who rush into arrangements without proper planning often face unexpected complications. Parents who sell quickly through traditional estate agents sometimes encounter chain collapses, gazumping, or lengthy delays that leave them in temporary accommodation whilst waiting for completion.
Another common theme is the importance of maintaining some financial independence for elderly parents. Families report better outcomes when parents retain sufficient capital for personal expenses, potential care needs, and the security of knowing they could establish independent accommodation if circumstances change.
At Property Saviour, we’ve helped numerous families avoid these pitfalls by providing guaranteed completion dates and fair prices that eliminate the uncertainty of traditional property sales. This allows families to make informed decisions about living arrangements without the pressure of uncertain property transactions.
Do I Need to Put Mum’s Name on My House Deeds?
Adding your mum’s name to your property deeds isn’t necessary for her to live with you, but some families consider this option for various reasons. Joint ownership can provide security for elderly parents, ensure they have legal rights to remain in the property, and potentially offer inheritance tax advantages.
However, joint ownership also creates complications. Your mum would have legal rights to the property that could affect your ability to remortgage, sell, or make changes. If she needs care in the future, her share of the property could be assessed for care fee contributions.
Most legal experts recommend keeping property ownership separate whilst documenting living arrangements through other means, such as family agreements or care arrangements that don’t affect property titles.
What Happens If Our Living Arrangement Doesn’t Work Out?
It’s essential to plan for the possibility that multi-generational living might not work long-term. Changes in health, family circumstances, or simply compatibility issues can mean alternative arrangements become necessary.
Preparing for changes:
Maintain financial reserves – Ensure your mum retains sufficient capital for alternative accommodation
Document arrangements – Clear agreements about living arrangements, financial contributions, and exit strategies
Regular reviews – Scheduled discussions about how arrangements are working for everyone
Professional support – Access to legal and financial advice when circumstances change
Alternative options – Research local care facilities, retirement housing, or other
How Much Should Mum Contribute to Household Expenses?
There’s no standard formula for financial contributions, but successful arrangements often involve transparent discussions about costs and fair sharing based on everyone’s circumstances. Consider these factors:
Household running costs to consider:
Increased utility bills
Higher food and household expenses
Additional insurance requirements
Council tax implications
Wear and tear on property and furnishings
Many families find that contributions covering the additional costs of having another adult in the household work well, rather than splitting everything equally. This recognises that your mum’s presence increases some costs but doesn’t necessarily double them.
Can We Sell Inherited House Together If Mum Lives With Me?
If your mum passes away whilst living with you, and you inherit her remaining assets, this creates different considerations from inheriting a separate property. The inheritance process is often simpler when assets are cash rather than property, but careful estate planning is still essential.
Inheritance tax still applies to cash gifts and remaining assets, but the administrative process is usually more straightforward than dealing with property probate. Having clear documentation about your mum’s living arrangements and financial contributions can help prevent family disputes and ensure her wishes are respected.
Sell Your Property in Days, Not Months
Selling a property through traditional estate agents or auction houses can be a frustrating and time-consuming ordeal. Estate agents often charge exorbitant fees, which can significantly eat into your profit margins. Their sales processes can be slow and unpredictable, leaving you in limbo for months on end. Auctions, on the other hand, are a gamble, with no guarantee of a sale or a fair price. You risk selling your property for a fraction of its true value, and buyers may discover hidden problems after the sale, leaving you with a costly headache.
In contrast, selling to Property Saviour offers a swift and stress-free solution. We provide instant offers with no hidden fees, and we cover at least £1,500 towards your legal fees. As genuine cash buyers, we don’t rely on mortgage financing, which eliminates the risk of the sale falling through due to financing issues.
