Shopping for a home in Saratoga and seeing list prices that start with a two or three? If so, you are likely looking at a jumbo mortgage. You want clarity on limits, rates, and what it takes to qualify so your offer lands without surprises. In this guide, you’ll learn the Santa Clara County jumbo threshold, common down payments and reserves, how pricing compares, the documents lenders expect, and a simple preapproval plan. Let’s dive in.
A jumbo loan is any mortgage that exceeds your county’s conforming loan limit. In Santa Clara County for 2024, the one‑unit conforming limit is $1,149,825. Any loan amount above that is a jumbo.
What this means on the ground: on a $2,500,000 purchase with 20% down, your loan would be about $2,000,000, which is above the county limit and therefore a jumbo. Because many Saratoga homes trade well above national averages, jumbo financing is common here. Limits are reviewed each year, so confirm the current figure with your lender before you lock plans.
Jumbo loans are not purchased by Fannie Mae or Freddie Mac, so pricing follows investor demand. In many mid‑2020s market cycles, jumbo rates run about 0 to 50 basis points higher than comparable conforming loans for well‑qualified buyers. That spread can shrink or widen based on market conditions and loan features.
Expect higher appraisal diligence on luxury properties, which can add cost and time. Mortgage insurance is less common for jumbos above 80% loan‑to‑value. Some lenders offer structured options, but most favor larger down payments instead of traditional PMI.
For a primary residence, many jumbo programs price best at or below 80% LTV, which is 20% down. Select lenders will go to 90% LTV for very strong borrowers, but rates, fees, and reserve requirements are usually higher. Second homes and investment properties typically require larger down payments, often 20% to 30% or more.
Reserves matter with jumbos. Plan for 6 to 12 months of PITI in liquid or vested assets for a primary residence, with more required as loan size rises or income gets more complex. Lenders will review where funds are held, that they are seasoned, and that they are accessible.
Strong credit helps your pricing. Many jumbo programs offer best terms with mid‑700s scores. Some lenders accept lower scores with tighter terms, but pricing often reflects the added risk.
Debt‑to‑income ratios commonly align with conforming standards around 43% to 50%. Lower LTVs, larger reserves, or stronger assets may allow more flexibility depending on the program and lender.
Jumbo underwriting rewards complete, clean files. Here is what lenders typically request:
Large or unexplained deposits will be questioned, so prepare clear documentation upfront. The more complete your packet, the faster an underwriter can issue a strong preapproval.
Expect a full interior and exterior appraisal by a certified appraiser experienced with luxury properties. For unique estates or very high values, the lender may require a second appraisal or a review. Features like acreage, equestrian elements, or extensive custom work require appraisers who understand local comparables.
Condos often involve project review and additional documentation. Properties with ADUs or multi‑unit layouts can have different underwriting rules, so confirm eligibility early. Title and insurance limits will scale with loan size, and specific endorsements may be required.
Set yourself up to win in a competitive Saratoga market with these steps:
Jumbo appraisals and underwriting can take longer than conforming files, especially for custom or high‑value homes. Build in extra time when you write your offer and discuss contingency timelines with your lender and agent. Because jumbo pricing can move independently, talk through lock strategy early and understand extension costs.
Most Saratoga purchases will require jumbo financing unless you are buying well below the area’s typical price range or bringing significant cash. With strong credit, a thoughtful down payment, documented reserves, and a fully underwritten preapproval, you can compete with confidence. If you are a relocating executive or a buyer with RSUs, gather your equity documents now so underwriting is smooth.
