Your Guide to Helping Your Child Buy Their First Home

Published March 2026

For many parents, helping a child buy their first home feels like a natural next step. In high-cost markets like Northern California, it’s increasingly common.

What matters isn’t just whether you help — it’s how the help is structured.

Parents often assume the process is simple: transfer some money, help with the mortgage, and move forward. But depending on how the assistance is arranged, it can create very different outcomes when it comes to tax reporting, ownership rights, loan qualification, and long-term financial planning.

Families today typically use one of four approaches when helping a child purchase property:

  1. Providing a down payment gift or loan

  2. Equity sharing (co-ownership)

  3. Purchasing through a family trust

  4. Co-signing the mortgage to help the child qualify

Each option solves a different problem and comes with its own tax and financial considerations.

Below is a practical breakdown of how each structure works and when families tend to use it.

Why Parents Are Helping More First-Time Buyers

Across the country — and especially in California — first-time home buyers face higher barriers than previous generations.

The biggest challenges are usually:

Higher cost of home ownership relative to income, compared to previous generations
Tougher lending standards and higher down payment requirements
• Competing with cash buyers and move-up buyers

Many buyers today have solid careers and income but simply haven’t had enough time to accumulate the capital and/or credit required to enter the market.

As a result, parents who help their children make a home purchase have become much more common.

Option 1: Helping With the Down Payment (Gift or Family Loan)

This is the most straightforward way parents help a child purchase a home.

Parents provide funds for the down payment, while the child qualifies for the mortgage independently.

This assistance is usually structured as either:

A down payment gift
A documented family loan

When this structure makes sense

This option works well when the buyer:

• Has strong income and stable employment
• Qualifies for the mortgage on their own
• Simply needs help saving enough for the down payment

Many young professionals fall into this category. They can comfortably afford the monthly payment but haven’t accumulated the upfront cash required in competitive housing markets.

Tax considerations when gifting a down payment

If parents gift money for a house down payment, the IRS allows annual tax-free gifts up to the yearly exclusion limit.

For 2026, the annual federal gift tax exclusion is $19,000 per recipient. This means a parent can give up to $19,000 to a child in a single year without needing to file a gift tax return. If both parents are contributing, they can combine their exclusions and gift up to $38,000 to the same child in one year without triggering gift tax reporting requirements.

Larger gifts are still allowed, but they typically require filing IRS Form 709 to report the amount above the annual exclusion. In most situations, families do not actually pay gift tax unless total lifetime gifts exceed the federal lifetime exemption.

Lenders will also require documentation confirming that the funds are a true gift with no repayment expectation.

Family loan considerations

If the money is structured as a loan instead:

• The loan terms should be documented
• Interest may need to be charged at the Applicable Federal Rate (AFR)
• Informal loans without documentation can create tax complications

For simplicity, many families prefer the gift structure, provided it aligns with their broader financial planning.

Option 2: Equity Sharing (Parents as Co-Owners)

Another option is equity sharing, where parents contribute funds in exchange for partial ownership of the property.

Instead of simply helping with the purchase, parents become co-owners and investors in the home.

For example:

• Parents contribute a portion of the purchase price
• The child contributes what they can
• Ownership percentages are defined in advance

When the home is eventually sold, proceeds are distributed according to that ownership structure.

When families choose equity sharing

This approach is often used when:

• Parents want their contribution treated as an investment rather than a gift
• The child cannot comfortably afford the purchase alone
• The home will serve as a multigenerational living space

It can also reduce the child’s monthly mortgage burden depending upon how the purchase is structured.

Tax considerations for shared ownership

Because parents hold an ownership interest, there are important tax implications.

When the home is eventually sold:

• The child may qualify for the primary residence capital gains exclusion
• Parents typically do not qualify for that exclusion unless they live in the property
• Parents may owe capital gains tax on their portion of the appreciation if it is an investment 

Ownership agreements should clearly define:

• Equity percentages
• Responsibility for expenses
• Exit strategies if the property is sold or refinanced

Most families use a tenancy-in-common agreement or similar legal structure.

Option 3: Purchasing the Home Through a Family Trust

Some families choose to purchase property through a family trust, especially when estate planning is already part of the conversation.

In this structure:

• The trust owns the property
• The child may live in the home as a beneficiary
• Ownership and inheritance rules are defined within the trust

When trust ownership makes sense

This structure is most common when:

• Parents already have an established estate plan
• The property is intended to stay in the family long-term
• The purchase is part of broader wealth planning

Trust ownership is less about helping the child qualify for a loan and more about long-term control and estate planning.

Tax considerations

Trust taxation depends heavily on the type of trust used.

Potential considerations include:

• Capital gains treatment when the property is sold
• California property tax reassessment rules
• Estate tax implications

Because these issues vary widely, trust-based purchases should always involve an estate attorney and tax advisor.

Option 4: Co-Signing the Mortgage

Another common strategy is co-signing a mortgage for your child.

In this situation, the parent does not necessarily provide cash but helps the child qualify for financing by adding their income and credit profile to the loan application.

When parents co-sign a mortgage

Co-signing is typically used when:

• The child has strong income but limited credit history
• Debt-to-income ratios are slightly too high for independent approval
• Parents want to help the child qualify without contributing a large down payment

This is common with buyers who are early in their careers but have strong long-term earning potential.

Financial and tax considerations

Co-signing a loan creates real financial responsibility.

Important implications include:

• The mortgage appears on the co-signer’s credit report
• It may affect the parent’s ability to qualify for future loans
• If payments are missed, the co-signer is legally responsible

From a tax standpoint:

• Co-signers generally cannot deduct mortgage interest unless they are also owners and making payments
• Ownership and loan responsibility should be clearly documented

Many families plan for a future refinance that removes the co-signer once the child’s financial profile strengthens.
