Question 1

What is the jumbo loan threshold in San Bernardino County?

Accepted Answer

Any loan amount above the FHFA conforming limit is jumbo. San Bernardino County's limit follows the standard FHFA baseline for most areas.

Question 2

Can I get a jumbo loan with a 680 credit score?

Accepted Answer

Most jumbo lenders require 700 or higher. A 680 score significantly limits your options and typically means higher rates.

Question 3

How much do I need for a down payment on a jumbo in Hesperia?

Accepted Answer

Most lenders want 20% down. Some allow 10-15% down with stronger credit and reserves, but options narrow fast below 20%.

Question 4

Do jumbo loans take longer to close?

Accepted Answer

Yes, typically. Underwriting is manual and more involved. Budget 45-60 days, especially if an appraisal needs revision.

Question 5

Is a jumbo ARM a good idea right now?

Accepted Answer

With rates elevated as of March 2026, an ARM can lower your initial payment on a large balance. Discuss the rate adjustment risk with your broker before committing.
