While the simplest way to financially assist an adult child is by way of a gift, in 2025 tax-free gifts are limited to $19,000 annually ($38,000 per married couple), which may not provide enough cash for a down payment. Of course, you can gift more than this annual exclusion amount, but any excess will have to be reported on IRS Form 709 and will count against your lifetime estate and gift tax exemption. However, instead of liquidating some of your assets to fund a cash down payment (and potentially incurring gift taxes), you might want to consider alternative solutions such as intrafamily loans, co-signed mortgages or other ways to leverage your existing assets.
With intrafamily loans, you act as the banker for your child or grandchild — setting up an interest-bearing promissory note that charges a minimum interest rate set forth by the IRS (the Applicable Federal Rate). Benefits of this strategy include:
- Mandated interest rates that are usually well below the rates charged by traditional lenders
- A great deal of flexibility regarding repayment terms
- Can be set up for any duration
- Require no mandatory fees, credit checks or collateral requirements, but do require you to keep written documentation for the IRS
You could potentially help a child or grandchild qualify for a better mortgage rate or larger loan by co-signing or guaranteeing the mortgage — where you agree to the mortgage terms (and assume liability for the debt if they default) but owe nothing and own nothing by co-signing.
Alternatively, you could help them purchase or refinance up to 100% of their primary home’s value by pledging eligible Merrill securities through our Parent Power® program without co-signing for the mortgage. You may also utilize a Loan Management Account® (LMA® account) or a home equity line of credit (HELOC). These options let you help a family member with their home ownership goals without selling your portfolio assets.
