03
Jumbo lenders in California are selective. They want strong credit, significant reserves, and documented income. Most jumbo shops are portfolio lenders or correspondent banks, not the big retail names.
Underwriting takes 45-60 days for jumbo. Appraisals are stricter. The lender will verify employment, assets, and tax returns thoroughly. Expect more scrutiny than a conventional $500,000 loan.
04
Jumbo makes sense in Martinez when you're buying above $1,249,125 and have the down payment ready. The 5.875% rate is competitive for this tier. If you're stretched on reserves or credit, conventional below the limit is easier.
The real advantage is rate stability. Jumbo 30-year fixed locks in for 30 years with no adjustments. That certainty matters when you're carrying a $1,249,125 loan.
05
A conventional loan maxes out at the $1,249,125 conforming limit. Above that, jumbo is your only path. Jumbo rates typically run 0.125% to 0.5% higher than conforming, but you're buying a home that conventional can't touch.
The tradeoff is underwriting rigor. Jumbo lenders dig deeper into reserves and income. Conventional is faster and looser. But if you're buying $1.5 million, you expect that scrutiny.
06
Brentwood's $155 million East County Service Center is under construction. That's county-level infrastructure investment that supports property values across the region. Jumbo buyers in Martinez benefit from the same county services expansion.
Richmond parks are getting multi-million dollar upgrades with state and federal funding. New soccer fields, lighting, and restrooms signal ongoing community investment. These improvements matter for long-term home appreciation.
07
Jumbo lending in California has tightened in recent years. Lenders are selective about borrower profiles and property types. Martinez buyers in this tier are typically repeat investors or high-net-worth professionals.
Jumbo closings in Contra Costa County happen regularly, but volume is lower than conventional. The market is stable. Rates have settled after 2023-2024 volatility. Buyers locking in now have predictability.

Yes. Jumbo lenders require 20% down minimum. On a $1,561,406 purchase, that's $312,281 at closing. Anything less and the loan doesn't qualify for jumbo pricing.
Plan on 45 to 60 days for jumbo approval. Lenders verify employment, assets, and tax returns thoroughly. Appraisals are stricter than conventional, which adds time.
740 FICO is the minimum for jumbo approval. Stronger scores (760+) improve your rate and approval odds. Below 740, most jumbo lenders will decline.
Unlikely. Jumbo lenders want 6 to 12 months of reserves in liquid assets. That's non-negotiable for loans above the conforming limit. Reserves protect the lender if you face hardship.
