Research findings published by Yahoo reveal that nearly a quarter of parents with adult children have had them “boomerang” back home to live. Additionally, a survey of UK adults aged 18 to 75 by Fair4All Finance found more than 20% had borrowed from friends and family in the past 12 months.
While helping friends and family financially might feel like a meaningful way to use your wealth, it’s crucial to set boundaries to protect your financial wellbeing and long-term security.
Keep reading to learn why financial boundaries are so important and find out how to protect yourself in situations where they are often overlooked.
Why financial boundaries matter
Financial boundaries are the limits and rules you set with yourself and others about how you manage your money. For example, you might give yourself a firm budget for non-essential spending each month or refuse to lend more money to a friend until they’ve repaid what they already owe you.
When supporting friends or family financially, financial boundaries help to:
- Reduce the risk of misunderstandings and conflict
- Protect your financial independence and security
- Encourage your loved one to be financially independent.
As such, taking a considered and structured approach to the financial support you offer could protect you and your relationship with those closest to you.
3 situations where you might overlook financial boundaries – and what to do about it
You might feel awkward discussing money with friends and family, but as discussed above, putting boundaries in place could benefit everyone involved. Here are three times you might want to consider setting a few ground rules around the support you offer:
1. When adult children move back home
One of the highest everyday costs most of us have is accommodation. So, if your children are struggling financially, allowing them to move back home might seem like a smart move.
However, the hidden costs of rent-free or low-rent living could quickly mount up and may include:
- A larger food bill
- Increased utility charges
- Greater car running costs if you share a vehicle with your children
- Higher Council Tax, for example, if you previously received the single occupancy discount.
What seemed like a straightforward and affordable option initially could diminish your savings and affect your standard of living over time, potentially leading to resentment and family tensions.
How to set boundaries:
- Agree on how you’ll share household bills.
- Set a time limit on the arrangement, after which your child or children must move out.
- Charge a nominal rent to foster responsibility and help your child save for their own place.
- Consider putting all of this in writing to ensure everyone has the same expectations.
2. Giving family loans
It’s often hard to say “no” to a friend or family member in need, especially if you have a comfortable lifestyle.
However, without clear boundaries in place, family loans come with a few potential risks:
- Repayments stop when life events, such as redundancy, present new financial challenges.
- Your relationship breaks down due to resentment about the debt or non-payments.
- Having money tied up in a family loan means you miss opportunities to grow your wealth.
- If you’re relying on a verbal agreement, you may have no way to recover any unpaid debt.
In other words, what you intended as a small, one-off loan could become a drain on your finances and your relationship.
How to set boundaries:
- Set a deadline for the loan to be paid in full.
- Use a formal loan agreement drafted by a solicitor.
- Consider charging interest, even if this is well below market rates.
- Run the numbers first to ensure you could cope financially if the loan is never repaid.
3. Renting investment properties to friends
Letting your loved ones rent a home from you might seem like a win-win; they get a comfortable and affordable property, and you gain a tenant you know and trust.
There are, however, some potential drawbacks to consider and guard against:
- You might feel uncomfortable chasing late or missing rent payments from friends.
- If things turn sour, eviction may be tricky without a formal tenancy agreement in place.
- Relying on your friendship rather than references could result in unplanned costs, such as property damage.
- Renting to friends informally could lead to mortgage and tax complications down the line.
How to set boundaries:
- Treat your friends as commercial tenants – for example, request references and run credit checks.
- Use a legally binding contract, such as an Assured Shorthold Tenancy (AST).
- Protect the deposit using one of the three government-approved schemes for ASTs.
- Separate the rental arrangement from your friendship by using a letting agent to handle rent collections, inspections, and so on.
