Using a Cash-Out Refinance to Help Your Adult Child Buy a House

A cash-out refinance replaces your existing mortgage with a new, larger one and returns the difference to you in cash at closing. Parents use it here because the money they want to give is already tied up in the house, and selling investments or draining retirement accounts can carry tax consequences that home equity does not.

The appeal is straightforward: the equity is sitting still, and the help is needed now. Real estate does not let you take a partial withdrawal, so a refinance is one of the few ways to convert some of that position into usable funds without selling.

What gets skipped in that reasoning is that the cash is not free. You are borrowing against your own home, on new terms, and the cost of that shows up in your budget every month for as long as the loan lasts. That trade can absolutely be worth it. It just needs to be a decision, not an assumption.

When parents give a child money for a home purchase, lenders treat it as a gift, and gifts have to be papered properly or they hold up the child's loan. The core document is a gift letter, signed by the person giving the money, stating the amount, the relationship, the property address, and that no repayment is expected. That last part is not decorative. If the money is a loan, it is a debt, and it changes the child's qualifying picture.

Underwriting also wants a paper trail showing where the money came from and where it went. That usually means a statement showing the funds in the parents' account, evidence of the transfer, and a matching deposit on the child's side. Wire transfers are cleaner than cashier's checks, and cashier's checks are cleaner than cash.

Timing matters more than people expect. If the money lands in the child's account and then sits for a while, some of the sourcing questions ease up. If it arrives mid-underwriting, expect the lender to trace every dollar. Coordinating the refinance closing with the child's purchase timeline saves a lot of scrambling later.

You are giving up your current mortgage. If the loan you have carries an APR well below what is available today, refinancing means retiring that rate permanently and taking on the current one across a larger balance. For some households the math still works. For others, the loss of the existing terms is the single biggest cost of the whole plan, and it is worth pricing out on the rates page before going further.

Your monthly obligation changes, and so does your equity position. Cash-out refinances are underwritten to a loan-to-value limit, meaning the lender will only let the new balance reach a certain percentage of the home's appraised value. How much room you have depends on your value and your current balance, and it caps how much you can actually hand over regardless of what your child needs.

There is also the reserve question. Parents who qualify comfortably tend to have savings, retirement, and equity all working together. Moving a large piece from the equity column into someone else's down payment shifts that balance. It is not necessarily wrong. It just means fewer cushions if something unexpected shows up on your side of the ledger.

A cash-out refinance is not the only structure. A home equity line of credit leaves your existing first mortgage untouched, which matters a great deal if that mortgage carries an APR you would not want to give up. The tradeoff is that lines of credit typically carry variable pricing, so the cost can move on you.

Some families skip the gift entirely and have the parents co-sign or buy the property jointly. That keeps the equity in place, but it puts the new mortgage on the parents' credit and counts against their debt picture for future borrowing. It also creates ownership questions that are easier to handle deliberately than to unwind later.

Others give a smaller amount and let the child carry more of the loan. Less help, less disruption. Comparing the structures side by side is usually more useful than deciding between doing it and not doing it. You can read more about the range of options on the loan types page.

Start with what the help is actually for. Closing a down payment gap, buying down a purchase price, or covering closing costs are different amounts with different urgency, and the number often shrinks once it is defined precisely.

Then look at your own position honestly. What does your payment obligation become, how long do you intend to stay in the home, and does the new structure still leave you where you want to be if income or plans change. If you are planning to sell within a few years, the cost of refinancing has less time to justify itself.

Finally, talk to your child's lender early. The gift documentation requirements vary by loan type, and knowing them in advance keeps a well-intentioned transfer from becoming an underwriting problem two weeks before their closing date.
