in Brentwood, CA
Brentwood home prices often sit right at the edge where conventional loans max out and jumbo loans begin. Understanding which loan type you need matters because it affects your rate, down payment, and approval odds.
The line between these loans shifts with conforming limits. For 2026, that limit is $1,249,125 in Contra Costa County — anything above that requires a jumbo loan.
Conventional loans stick to FHFA conforming limits, which means they're easier to sell on the secondary market. That makes lenders more comfortable offering lower rates and accepting smaller down payments — as low as 3% for first-time buyers.
Credit requirements run stricter than FHA but more flexible than jumbo. Most lenders want 620 minimum, though you'll get better pricing at 740+. Debt-to-income ratios can stretch to 50% with strong compensating factors.
Jumbo loans exceed conforming limits, which means lenders carry more risk since these loans can't be sold to Fannie Mae or Freddie Mac. That risk translates to tighter qualification standards — higher credit scores, larger reserves, and stricter income documentation.
Most jumbo lenders want 700+ credit and 10-20% down, though some programs allow less. You'll typically need 6-12 months of reserves and a debt-to-income ratio under 43%. Rates vary by borrower profile and market conditions.

Brentwood home prices often sit right at the edge where conventional loans max out and jumbo loans begin. Understanding which loan type you need matters because it affects your rate, down payment, and approval odds.
The line between these loans shifts with conforming limits. For 2026, that limit is $1,249,125 in Contra Costa County — anything above that requires a jumbo loan.
Conventional loans stick to FHFA conforming limits, which means they're easier to sell on the secondary market. That makes lenders more comfortable offering lower rates and accepting smaller down payments — as low as 3% for first-time buyers.
The approval gap between these loans is real. Conventional loans offer standardized underwriting that's predictable. Jumbo underwriting varies by lender — each portfolio lender sets their own rules, which creates opportunity for borrowers with strong profiles but unique situations.
Pricing also differs. Conventional rates tend to run lower because of secondary market liquidity. Jumbo rates used to always cost more, but competitive lender portfolios have closed that gap. Sometimes jumbo rates even beat conventional when credit scores exceed 760.
Down payment flexibility separates them most. Conventional allows 3-5% down for qualified buyers. Jumbo typically requires 10% minimum, though 20% down avoids higher rate adjustments and gets you the cleanest approval.
Your purchase price makes this decision for you in most cases. Under $832,750, conventional wins on flexibility and approval ease. Above that threshold, jumbo is your only conforming option unless you're willing to carry a second mortgage.
If you're shopping near the conforming limit, consider your full financial picture. A $750,000 home lets you use conventional with easier approval. A $800,000 home needs jumbo, which requires stronger credit, more reserves, and typically a larger down payment.
