The Family Mortgage: How High-Net-Worth Parents Are Financing Their Children’s Homes

If you’re watching your adult children struggle to buy their first home in today’s challenging market, you’re not alone. With rising interest rates and steep down payment requirements, many parents want to help – but might worry about the best way to do it. While gifting a down payment might seem like the simplest solution, there’s another option worth considering: the intra-family loan.

I’ve seen many families use these loans successfully, creating win-win situations that benefit both parents and children. Let’s explore why this approach might be smarter than simply writing a check, and how to structure it properly.

Why Consider an Intra-Family Loan Instead of a Gift?

Think of an intra-family loan as having your cake and eating it too. Your kids get the help they need, while you maintain better control over your assets and create teaching moments about financial responsibility. Here’s what makes these loans particularly attractive:

You can charge lower rates than banks. With current mortgage rates hovering around 7%, you might be able to offer your children a rate around 4-5% (as long as it meets IRS minimums). Your kids save money, while you could earn more than you might from many conservative investments. Keep in mind that interest payments received will be taxable as income to you as the lender. However, the interest deduction may still be available to your children if the loan is properly structured and secured by the home.

Plus, you have flexibility that no bank would offer. If your children hit a rough patch or face unexpected expenses, you could choose to forgive some interest payments (though this would be considered a gift for tax purposes) or restructure the loan terms. This flexibility can provide valuable peace of mind for both parents and children, knowing there’s a safety net in place should circumstances change.

There’s a strategic gift tax angle too. When structured properly, these loans help you transfer wealth to your children without eating into your lifetime gift tax exemption. Instead of giving away money outright, you’re creating a tax-efficient way to help your children while preserving your estate planning flexibility.

Another significant advantage? Lower closing costs and minimal underwriting requirements. Since you’re not working with a traditional bank, you can bypass many of the usual mortgage closing costs like origination fees, application fees, and points. You also avoid the lengthy and complex underwriting process that banks require – no need for extensive income documentation, employment verification, or credit checks (though you may still want to discuss your child’s ability to repay). While you’ll still need to pay for legal documentation and recording fees, these costs are typically much lower than traditional mortgage closing costs, which can run into thousands of dollars. The streamlined process not only saves money but also time and stress, allowing your children to move forward with their home purchase more quickly and efficiently.

Loan Structure Options: Finding the Right Fit

One size doesn’t fit all when it comes to family loans. Let’s look at your main options:

Traditional Amortizing Loans (15 or 30 years): This feels most familiar to everyone – regular monthly payments that include both principal and interest, just like a regular mortgage. It’s predictable and easy to understand, making it a popular choice for many families.

Interest-Only with Balloon Payment: Here’s where it gets interesting. Your kids only pay interest during the loan term, with the entire principal due at the end. This can make monthly payments much more affordable, but requires careful planning for that final balloon payment. Some families plan to forgive the balloon payment as part of their estate planning, though this requires careful consideration of gift tax implications.

Annual Payment Structure: Instead of monthly payments, everything’s handled once a year. This can be simpler to manage and might work better for some families’ cash flow situations. However, it requires more discipline from the borrower to set aside money throughout the year.

Demand Loans: These are more flexible – you can call the loan at any time. However, they require more attention because you need to adjust the interest rate periodically to stay compliant with IRS rules. They’re generally better for shorter-term situations.

Setting It Up Right: The Critical Details

Let’s be clear: this isn’t the time for handshake deals. You need proper documentation to make this work from both legal and tax perspectives. Here’s your checklist:

  1. Get the interest rate right. The IRS publishes minimum rates (called Applicable Federal Rates or AFRs) monthly. You must charge at least this amount – anything below the AFR will be considered a partial gift by the IRS, with the difference between your rate and the AFR treated as a taxable gift. This could unexpectedly eat into your lifetime gift tax exemption or even trigger gift tax liability.
  2. Create proper loan documentation. You need:
    • A formal promissory note
    • A detailed loan agreement
    • A mortgage or deed of trust if you’re securing the loan
    • Payment schedules and amortization tables
  3. Record the mortgage if you’re securing the loan. This protects your interests and can make the interest tax-deductible for your children.

Avoiding the Pitfalls: What Could Go Wrong?

Family loans come with unique challenges. Here’s what to watch out for and how to handle it:

Family Dynamics: Be upfront about how this might affect relationships with other children. Consider whether you’ll need to offer similar help to siblings to maintain family harmony. Document everything clearly to avoid future misunderstandings.

Default Scenarios: Nobody likes to think about it, but you need a plan. What happens if your child can’t pay? Will you modify the loan? Forgive portions? Having these discussions upfront prevents bigger problems later.

Tax Compliance: The IRS pays attention to family loans. Charge too little interest, and they might recharacterize part of the loan as a gift. Fail to document properly, and you might lose interest deductions. Getting professional tax advice isn’t just helpful – it’s essential.

  • Recording Fees: $400

Key Observations

  1. The intra-family loan requires no down payment, freeing up $200,000 in initial capital
  2. Closing costs are significantly lower with the intra-family loan ($14,100 less)
  3. Despite financing the entire purchase price, the intra-family loan has lower monthly payments ($264 less per month)
  4. Over the life of the loan, the intra-family loan saves approximately $295,025 in interest payments
  5. The total cost difference over 30 years, including closing costs, is $309,125 in favor of the intrafamily loan
  6. Instead of paying $1,104,447 to banks and third parties (interest + fees), $792,122 stays within the family as wealth transfer between generations

Important Considerations

  • The traditional mortgage rate used (6.85%) reflects current market rates as of January 2025
  • The intra-family loan rate (4.35%) uses the minimum applicable federal rate (AFR) for mid-term loans
  • Both scenarios assume a 30-year fixed rate loan
  • Additional costs such as property taxes and insurance are not included in these calculations
  • The intra-family loan’s 0% down payment structure requires significantly more family resources upfront but provides maximum leverage for the buyer
  • Traditional mortgage closing costs can vary by lender and location
  • Intra-family loan closing costs primarily consist of legal fees to ensure proper documentation

Frequently Asked Questions

Will this affect my child’s ability to get a traditional mortgage?

Yes, it will be considered in their debt-to-income ratio. However, some families structure the loans with deferred payments specifically to help qualify for bank mortgages.

Can we refinance if interest rates change?

Yes, but you’ll need to use the current AFR rate and create new documentation. Many families build in refinancing provisions from the start.

What happens if I need the money back sooner than planned?

This is why clear documentation is crucial. Consider including provisions for early repayment or modification of terms.

Next Steps

If an intra-family loan sounds right for your situation, start with two key steps:

  1. Schedule a family meeting to discuss the concept and gauge everyone’s comfort level.
  2. Set up consultations with your tax advisor and attorney to explore specific structuring options.

Remember, while the paperwork might feel formal for a family transaction, it’s this very formality that protects everyone involved and ensures your good intentions don’t create unintended consequences.
