$30,250 more down. $99,976 saved.
Santa Clara's high-balance conforming limit is $1,209,750. One dollar over it and your loan re-prices as a jumbo. Most borrowers who land just over that line never learn they could have stepped back under it — for a fraction of what it costs them.
A jumbo loan is any mortgage above the conforming loan limit set for your county. In the Bay Area's high-cost counties — Santa Clara, San Francisco, San Mateo, Alameda — the 2025 high-balance conforming limit is $1,209,750. Below it, your loan is bought by Fannie Mae or Freddie Mac and priced accordingly. One dollar above it, and it is a jumbo: held on a bank's balance sheet, underwritten harder, and priced higher. The consequence almost nobody is told: if you land just over the line, increasing your down payment slightly can push you back under it. On a $1,550,000 purchase, $30,250 more down saves roughly $99,976 in lifetime interest. An important note: a standard jumbo is full-documentation. It is not a Non-QM loan. If you can document your income, take the jumbo — not the Non-QM product.
How far over the line are you?
Move the price and the down payment. The moment your loan crosses the limit, the whole thing re-prices.
Watch the verdict flip as you push this up. That is the cliff.
$30,250 over the limit. You are barely over the cliff — and you can step back.
You are $30,250 over the limit. Putting that same $30,250 down instead saves you $99,976. We are telling you to borrow less from us.
Two loans. One dollar apart.
Height is lifetime interest. The only difference between these two towers is whether your loan lands one dollar above or one dollar below a number set by a federal agency.
Limits change every year and vary by county. Adriana will check yours against the actual 2025 table — not a rule of thumb.
Illustrative only. Conforming loan limits are set annually by the FHFA and vary by county; the Bay Area high-cost limit shown ($1,209,750) applies to Santa Clara, San Francisco, San Mateo, Alameda, Marin and Contra Costa among others, and the baseline ($806,500) applies elsewhere. Jumbo pricing sometimes matches or beats conforming for very strong borrowers with large deposits — the premium is not a law, and we will check rather than assume. Not a commitment to lend. Equal Housing Opportunity.
Should you just borrow less?
There are exactly three ways back under the cliff. Two of them mean we make less money. Here they are anyway.
And the fourth option: take the jumbo. If you are far over the line, none of this applies — stepping under would mean a wildly different house.
You are over by $30,250. Find $30,250 — from the deposit, from a price negotiation, or from a combination — and the entire loan re-prices as conforming.
It saves roughly $99,976 in lifetime interest. That is a return of about 3.3× on the cash, which is not a rate of return you will find anywhere else in this transaction.

What is the conforming loan limit in the Bay Area?
For 2025, the high-balance conforming limit in high-cost counties including Santa Clara, San Francisco, San Mateo, Alameda, Marin and Contra Costa is $1,209,750. The baseline limit for most other counties is $806,500. Above your county's limit, the loan is a jumbo.
Is a jumbo loan a Non-QM loan?
No, and this confusion costs people money. A standard jumbo is a full-documentation loan — tax returns, W-2s, the lot. It is simply too large to be bought by Fannie Mae or Freddie Mac, so a bank holds it. Non-QM refers to how you prove income, not how big the loan is. If you can document your income, take the jumbo and do not pay a Non-QM premium you do not owe.
How much more does a jumbo cost than conforming?
Usually a modest premium — often around 0.2 to 0.5 percentage points, though it varies and occasionally a jumbo prices better than conforming for very strong borrowers. The bigger cost is usually the underwriting: larger deposits, more reserves, tighter debt-to-income tolerance.
Can I avoid a jumbo by putting more money down?
Yes, and this is the single most useful thing on this page. If your loan lands just over the limit, increasing your down payment enough to bring the loan under it re-prices the entire mortgage as conforming. On a $1,550,000 purchase, roughly $30,250 more down can save close to $100,000 in lifetime interest. Very few loan officers volunteer this, because it means a smaller loan.
What is a piggyback or 80/10/10 loan?
A first mortgage at the conforming limit plus a second lien for the remainder, keeping the first loan conforming. It can work, but the second lien carries a higher rate and the arithmetic does not always favour it. We will run both and show you which actually wins — sometimes it is simply the jumbo.
Do jumbo loans require bigger reserves?
Generally yes. Where a conforming loan may want a couple of months of reserves, a jumbo lender frequently wants six to twelve months of full housing payments held in liquid assets after closing. Plan for it early; it catches people out at underwriting.
Are jumbo rates always higher?
No. The spread moves, and in some markets jumbos have priced at or below conforming, particularly for borrowers with large deposits and substantial assets held at the lending bank. It is worth checking rather than assuming, which is precisely why the rates on this page are inputs you can change.
What if I'm far over the limit?
Then take the jumbo, and stop optimising. If your loan is $2.1M in a county with a $1.21M limit, getting under the line would mean buying an entirely different house. The conforming-cliff strategy only helps borrowers who land near the line — and we will tell you plainly which one you are.
