If you're buying in Santa Clara County, getting help from family isn't unusual — it's often the difference between waiting another year and buying now. The good news: gift funds are a completely normal, well-established part of the mortgage process. The part people get tripped up on is that the rules shift depending on your loan program, and jumbo loans — which cover a huge share of Bay Area purchases — have their own wrinkle worth understanding before you ask a family member for help.

How Much Can Be Gifted, by Loan Type

For a primary residence, the general rule is generous: most loan programs let gift funds cover the entire down payment, not just a portion of it.

Investment properties are the one place gift funds generally aren't allowed at all — this is a primary-residence benefit across nearly every loan program.

The Jumbo Loan Wrinkle Bay Area Buyers Should Know

Because jumbo loans fall outside Fannie Mae and Freddie Mac's conforming guidelines, each lender sets its own rules — and most are more conservative about gift funds than conforming loans. Many jumbo programs want to see the borrower contribute a minimum portion of the down payment from their own funds before gift money is applied on top of it. The exact split varies by lender, loan amount, and how strong the rest of your file looks.

The other piece that surprises people: gift funds generally can't be used to satisfy post-closing reserve requirements on jumbo loans. Reserves — the liquid assets you're required to hold after closing, often several months of your full mortgage payment — need to be your own verified, vested assets. A gift can help you get to the closing table, but it typically can't substitute for the cushion a jumbo lender wants to see afterward.

None of this means gift funds don't work for a jumbo purchase — they absolutely can. It just means the plan needs to account for both pieces before you're mid-transaction.

What the Paper Trail Actually Looks Like

Lenders aren't being difficult when they ask for documentation on a gift — they're required to confirm the money is truly a gift and not an undisclosed loan that would affect your debt picture. Here's what to expect:

• A signed gift letter stating the donor's name, relationship to you, the amount, the date, and that no repayment is expected.
• Proof the donor had the funds — usually a bank statement showing the money was there before it moved.
• A traceable transfer — wire or check, never cash, so the lender can follow the money from the donor's account to yours.
• Timing matters: funds that have been sitting in your account for 60+ days generally need less documentation than a gift that arrives right before closing.

Getting the Timing Right

The biggest mistake I see: a family member sends the gift the week before closing, and suddenly everyone's scrambling for documentation under a deadline. If a gift is part of your plan, loop your lender in early — ideally when you're still house hunting, not once you're already in contract. That gives enough time to season the funds if needed and confirms exactly how much your specific loan program will allow before you're counting on a number that might not hold up.
