in San Ramon, CA
San Ramon's housing market pushes many buyers past conventional loan limits. Properties here routinely exceed the 2026 conforming limit of $1,249,125 for Contra Costa County.
The jump from conventional to jumbo financing changes your rate, down payment, and reserve requirements. Most San Ramon buyers need to understand both options before shopping seriously.
Conventional loans work for properties under $832,750. You can put down as little as 3% with decent credit, though you'll pay PMI until you hit 20% equity.
These loans get sold to Fannie Mae or Freddie Mac, which keeps rates competitive. Lenders price them aggressively because they can offload the risk to government-sponsored entities.
You need a 620 minimum credit score for most programs. Income verification follows standard W-2 and tax return patterns. Debt-to-income ratios max out around 50% with strong compensating factors.
Jumbo loans handle anything above $832,750 in San Ramon. Lenders keep these on their books instead of selling them, which makes underwriting stricter across the board.
Expect to put down 10-20% minimum depending on loan size. Credit score floors typically sit at 680-700. Reserves matter more here—most lenders want 6-12 months of payments in the bank after closing.
Rates on jumbos used to run higher than conventional. That gap has narrowed significantly. You'll sometimes see jumbo rates match or beat conventional pricing with strong credit and assets.

Conventional loans work for properties under $832,750. You can put down as little as 3% with decent credit, though you'll pay PMI until you hit 20% equity.
The biggest split is down payment flexibility. Conventional allows 3% down for qualified buyers. Jumbo starts at 10% minimum, with most lenders preferring 15-20% on larger balances.
Credit standards tighten on jumbo loans. A 620 score works for conventional. Jumbo underwriters want 680 as a floor, 700+ for best pricing. They scrutinize income stability and asset reserves much harder.
Loan limits create the clearest dividing line. If your San Ramon purchase price stays under $832,750, conventional gives you more options. Above that number, you're in jumbo territory whether you like it or not.
If you're buying under $832,750 in San Ramon, conventional wins on flexibility. Lower down payments, easier credit qualifications, and more forgiving DTI ratios make it the default choice for most buyers.
Above that threshold, jumbo is your only option unless you downsize your search. The good news: if you can afford a $900K+ home in San Ramon, you likely have the credit and reserves jumbo lenders want to see.
Some buyers split the difference with a conventional first and smaller second mortgage to avoid jumbo territory. This works when you've got 10% down but want to dodge jumbo requirements on a $800K purchase.

No, but you need strong credit. Most jumbo lenders require 680 minimum, with 700+ getting best pricing and easiest approval.
