Be the Bank: Intra-Family Loans & The AFR Strategy

Be the Bank: Intra-Family Loans & The AFR Strategy

Stop giving your children money; start lending it. How to use the “Family Bank” to finance your heir’s first home or startup at rates far below the market, without triggering a penny of gift tax.

Executive Summary

  • The Dilemma: Your daughter wants to buy a $2M home. Mortgage rates are 7%. If you give her $2M cash, you use up $2M of your Lifetime Gift Exemption (or pay 40% tax). If she borrows from a bank, she pays massive interest to strangers.
  • The Solution (Intra-Family Loan): You lend her the $2M. The IRS requires you to charge a minimum interest rate called the **Applicable Federal Rate (AFR)**. The AFR is almost always *lower* than commercial mortgage rates.
  • The Wealth Transfer:
    👉 Market Rate (7%) vs. AFR (e.g., 4%).
    👉 Your daughter saves 3% in interest annually. This saving is a **Tax-Free Gift**.
    👉 If the house appreciates at 5%, she keeps all the upside. You essentially transferred the asset’s growth to her without using your exemption.

The “Sham Transaction” Trap

Paperwork is Mandatory: You cannot just write a check and say “pay me back later.” The IRS will reclassify undocumented loans as **Gifts**, triggering immediate taxes.
👉 The Protocol: You must have a signed **Promissory Note**. You must record a **Mortgage Lien** (Deed of Trust) if it’s for a house. You must collect interest payments annually and declare them as income on your tax return. Treat it like a real business.

Simulation: Funding a $2M Home Purchase (Bank vs. Dad)

Total Interest Paid by Child
Commercial Bank (7%)$2.8M Interest Cost
Over 30 years, the interest paid to the bank exceeds the cost of the house. Wealth leaks out of the family.
Family Bank (AFR 4%)$1.4M Interest Cost
Interest stays IN the family (Dad receives it). The child saves $1.4M. Win-Win.
Forgiveness OptionEffective Rate ~0%
Dad uses his Annual Gift Exclusion ($19k/yr) to “forgive” the interest payment each year. Child pays nothing.
Feature Outright Gift Intra-Family Loan
Gift Tax Exemption Used Immediately (100% Value) Preserved ($0 Used)
Asset Protection Exposed to Child’s Divorce Protected (Dad is a Creditor)
Psychology Entitlement (“My Money”) Responsibility (“Debt to Repay”)

“Money ruins children when it is given without context. The Family Bank changes the dynamic from ‘Parent-Child’ to ‘Lender-Borrower.’ It allows you to help them, while maintaining the leverage to enforce good behavior.”
