in Martinez, CA
Martinez sits in Contra Costa County, where the 2026 conforming limit is $1,249,125. Buyers above that threshold need jumbo financing. The median household income here is $125,727, so many local buyers are shopping in the conforming range.
Conventional loans follow Fannie Mae and Freddie Mac rules. Jumbo loans are portfolio products for purchases above the conforming cap. Both have their place depending on your price point and down payment.
Conventional loans are the standard path for homes under the conforming limit. They're backed by Fannie Mae or Freddie Mac, which means consistent underwriting and broad lender availability. Most conventional buyers put 5% to 10% down at closing.
PMI applies when you put down less than 20%. The good news: PMI cancels automatically at 80% LTV once you've paid the loan down. Conventional rates tend to be competitive because the secondary market is deep and liquid.
Jumbo loans finance purchases above $1,249,125. They're held by the lender or sold to private investors, not Fannie Mae. Jumbo borrowers typically put 10% to 20% down because lenders want meaningful skin in the game.
Jumbo loans skip mortgage insurance entirely. Instead, lenders price the risk into the rate and may require larger reserves. The trade-off: a slightly higher rate in exchange for no PMI and a simpler closing.
Local decision guide
Use this comparison to weigh Conventional Loans and Jumbo Loans through local payment fit, eligibility, documentation, and timing before choosing a path in Martinez.
Martinez sits in Contra Costa County, where the 2026 conforming limit is $1,249,125. Buyers above that threshold need jumbo financing. The median household income here is $125,727, so many local buyers are shopping in the conforming range.
Conventional loans follow Fannie Mae and Freddie Mac rules. Jumbo loans are portfolio products for purchases above the conforming cap. Both have their place depending on your price point and down payment.
Conventional loans are the standard path for homes under the conforming limit. They're backed by Fannie Mae or Freddie Mac, which means consistent underwriting and broad lender availability. Most conventional buyers put 5% to 10% down at closing.
The biggest difference is the loan amount. Conventional maxes out at $1,249,125 in Contra Costa County. If you're buying above that, jumbo is your only option. Below that, conventional is usually cheaper because PMI is temporary and rates are tighter.
PMI versus no insurance is the second difference. Conventional buyers with less than 20% down pay PMI until they hit 80% LTV. Jumbo borrowers skip PMI but accept a higher rate to compensate.
Jumbo lenders are pickier about reserves and credit. They want to see 6–12 months of mortgage payments in the bank after closing. Conventional has more flexibility. If you're stretched on reserves, conventional with PMI might be easier to close.
Pick conventional if you're buying below $1,249,125 and have at least 3% down. The median household income in Contra Costa is $125,727, which supports a conforming purchase in the $500,000–$700,000 range comfortably.
Pick jumbo if your purchase exceeds the conforming limit or if you have 15%+ down and want to skip PMI entirely. Jumbo makes sense for high-net-worth buyers who can meet reserve requirements.
The 2026 conforming limit in Contra Costa County is $1,249,125. Any purchase above that requires jumbo financing. Below that, conventional loans apply.
Yes — 20% down is the only way to skip PMI on conventional. Put down 3–19% and PMI applies until you reach 80% LTV. Then it cancels automatically.
Most jumbo lenders require 10% down minimum. Some will go to 5% for strong borrowers, but reserves and credit must be excellent. Conventional is easier if you want to put down 3–5%.
Usually. Jumbo rates run 0.25–0.5% higher because the lender holds the risk. The trade-off is no PMI. On a conforming loan with 15% down, PMI plus a lower rate may equal jumbo's all-in cost.
Jumbo lenders typically want 6–12 months of mortgage payments in reserves after closing. Conventional has no reserve requirement. If you're tight on liquid assets, conventional is simpler.
