Facing a 7% Mortgage? Here's how family loans could help buyers avoid high mortgage interest and unlock valuable tax savings

Mortgage Rates Near 7.3% Today: A 30-year mortgage is costing more again. Freddie Mac’s average rate reached 7.28% on October 1, 2026, up from 6.95% three weeks earlier. For a buyer borrowing $400,000, that rate works out to roughly $2,730 a month in principal and interest, before taxes, insurance and other housing costs. That has pushed some families to look at an arrangement that has nothing to do with a bank; borrowing from a parent, grandparent or another relative.

A properly structured family loan can give a younger family member access to money at a rate that may be below a conventional mortgage. It can also turn the older generation's cash into an income-producing asset. The tax rules are where the arrangement gets more complicated.

How families are quietly beating 7% mortgage rates while lowering their annual tax bills.

According to Freddie Mac, the average 30-year fixed rate recently reached 7.28%. That is up from 7.03% the previous week and 6.34% during the same period a year earlier.


White House officials argue that relief is coming soon. Kevin Hassett, director of the National Economic Council, recently stated that mortgage rates should fall "very quickly" as inflation moves toward 1% or 2%. He pointed to rising housing starts and permits as signs of economic strength.

Suppose a parent has enough savings to lend a child $400,000 for a home. Instead of the child paying mortgage interest to a bank, the child makes payments to the parent. The parent receives the interest income. The money stays within the family rather than going to an outside lender.

Federal tax rules contain provisions for below-market loans, and the IRS publishes applicable federal rates, or AFRs, for different loan terms. For October 2026, the annual mid-term AFR is 4.61%, while the long-term AFR is 5.22%.

That creates an important gap with today's mortgage market. A family loan priced around an applicable IRS rate could be cheaper for the borrower than a 7.28% conventional mortgage, while still giving the parent a defined stream of interest income.

The exact rate depends on the loan's structure and term. This isn't a situation where families should simply pick an IRS rate from a table and start transferring money.

The biggest misunderstanding is that a family loan automatically creates a tax deduction. It doesn't. For the borrower to potentially claim the home mortgage interest deduction, the debt generally must be secured by the qualified home, the borrower must have an ownership interest, and the taxpayer must itemize deductions.

The IRS also requires that both borrower and lender intend for the debt to be repaid. That means a written agreement matters. So do actual payments. A family arrangement that looks like a loan on paper but behaves like a gift can create tax problems.

Families should have the loan documented, establish a payment schedule, record interest and consider securing the debt against the property. An attorney or tax professional can help determine how those documents should be prepared.

There is another reason a loan can appeal to families with substantial assets. A direct gift transfers wealth immediately. A loan doesn't. The parent keeps a legal claim to repayment and receives interest along the way.

That can make the arrangement useful when parents want to help an adult child buy a home but aren't ready to give away hundreds of thousands of dollars.

The interest payments also have a different tax character from the original principal. Returning borrowed principal generally isn't income to the lender. Interest is taxable income.

So the family has to look at both sides of the transaction. A lower interest rate can reduce the child's borrowing cost, but the parent may owe income tax on the interest received.
