How to Help Your Adult Child Buy Their First Home

Quick answer

Parents can help a few different ways: gift part or all of the down payment, join the loan as a non-occupant co-borrower so their income helps the child qualify, cover closing costs or cash reserves, or start good savings and credit habits early. FHA loans make most of this straightforward — 3.5% down, gift funds allowed, and family co-borrowers permitted. The right mix depends on your budget and your child's income and credit. None of it guarantees approval, but the right structure can turn a “not yet” into a “yes.”

Start with what you're actually trying to do

Before you talk dollars, get clear on the problem you're solving. There are really only two: your child can't come up with enough cash up front, or their income isn't high enough yet to qualify for the payment. Those call for different kinds of help, and knowing which one you're facing saves a lot of confusion later.

• A cash gap means they need money for the down payment or closing costs — a gift or a loan from you can close it.
• An income gap means the lender's math says they can't afford the payment yet — that's where adding your income as a co-borrower comes in.
• Sometimes it's both, and you can combine help — for example, gift the down payment and co-sign the loan.

A quick call with a broker before you move money is worth it. The way help is structured affects the loan, so it's better to plan it than to fix it after the fact.

Which kind of help fits

Here's a plain comparison of the four most common ways parents help, so you can see at a glance where each one shines and what to watch for.

Illustrative only — your family's best option depends on income, credit, and how much you can comfortably contribute.

Way 1: Gift the down payment

On an FHA loan, the entire 3.5% down payment can come from a family gift, and gifts from relatives are allowed on conventional loans too. The money has to be a true gift — not a loan in disguise — so the lender will want a short gift letter and a record of the funds moving. It's simple once you know the steps, and it's the most common way parents pitch in.

• A signed gift letter stating the amount and that no repayment is expected.
• Proof the money came from you and landed in your child's account (statements or a wire record).
• Give the gift a little before the application when you can — a well-documented, “seasoned” deposit raises fewer questions.

Way 2: Add your income as a co-borrower

If your child's income doesn't quite cover the payment on paper, you can join the loan as a non-occupant co-borrower — you don't live in the home, but your income is added so the numbers work. FHA even keeps the down payment at 3.5% when the co-borrower is a close relative. The trade-off is real: your credit, your existing debts, and your name all go on the loan. It's the most powerful form of help and the one to think hardest about.

This one has enough detail to deserve its own guide — see the linked article on FHA non-occupant co-borrowers for exactly how the income and credit math works.

Way 3: Cover closing costs or reserves

Not every family needs to fund the whole down payment. Sometimes a child has saved most of it and just needs help over the last hurdle — closing costs, or the few months of “reserves” some loans want to see in the bank after closing. A smaller, targeted gift here can be the piece that gets the deal done, and it follows the same gift-letter rules as a down-payment gift.

Way 4: Help early — the cheapest help of all

The help that costs the least often does the most, and it starts long before house-hunting. If your child is still young, a few habits set them up to qualify on their own — or to need far less from you when the time comes.

• Open a savings account and build the down-payment habit early.
• Help them get one credit card used responsibly to build a credit history.
• Keep their name off co-signed car loans or debts that will crowd out a future mortgage.
• Talk openly about money — budgeting, rent versus owning, what a payment really includes.

A word on the “buy young” idea

You'll see a lot of talk online about buying a home at 22 and building wealth from there. There's a real kernel to it — owning earlier means more years of potential equity and a housing payment that doesn't climb the way rent can. But it isn't a sure thing. Home values rise and fall, ownership carries real costs and responsibilities, and it isn't the right move for everyone or every moment. Treat it as one option to weigh honestly, not a guarantee, and only when your child is genuinely ready to own.

How to decide together

The families who do this well slow down and treat it like the joint decision it is. A simple path keeps everyone protected and on the same page.

1. Run the real numbers first — payment, down payment, and what you can comfortably give without straining your own budget.
2. Have the honest family conversation about responsibility, especially if you're thinking about co-borrowing.
3. Get your child pre-approved so you're working with facts, not guesses.
4. Pick the help that fits — gift, co-borrow, or both — and document it the way the lender needs.

Common questions

Can I just give my child money for a down payment?

Yes. On an FHA loan the whole 3.5% down payment can be a family gift, and conventional loans allow relative gifts too. The lender will want a short gift letter and a record of the money moving, since it has to be a genuine gift and not a hidden loan.

Should I co-sign or just give a gift?

It depends on the gap. If your child qualifies on income but is short on cash, a gift is cleaner. If their income alone isn't enough to afford the payment, co-borrowing adds your income so they qualify — but it also puts your credit and debts on the loan. When it's both, families often do both.

Will helping my child hurt my own credit or ability to borrow?

A gift won't. Co-borrowing will show up on your credit and count as your debt too, which can affect your own future borrowing. That's the main reason to run the numbers and talk it through before signing rather than after.

How much do we need for a down payment in California?

FHA starts at 3.5% down. On a $500,000 home that's $17,500 before closing costs. Down-payment assistance and low-down conventional options can lower that further for buyers who qualify. The affordability calculator can show you a realistic target for your price range.

Is it better to help pay for college or help buy a home?

There's no single right answer — it depends on your family's goals, your child's plans, and your budget. Education and homeownership can both build a future, and many families do some of each over time. The point is to make it a deliberate choice rather than assuming college is the only way to help.

Can my child buy with an ITIN if they don't have a Social Security number?

Yes. ITIN home loans let buyers who file taxes with an ITIN qualify without a Social Security number, and parents can still help with a gift or as a co-borrower on the right program. It's one of the areas we work in most, so it's worth a conversation about which loan fits.
