The high-balance conforming loan limit for 2023 in Sonoma County is $861,350.

The “low-balance” conforming loan limit for 2023 in Sonoma County is $726,200.

  • Both loan limits above are based on a 1-unit property.

Loans between $726,200 and $861,350 in Sonoma County are considered high-balance conforming loans.  High-balance loans tend to come with slightly higher interest rates than loans under $726,200 (“low-balance”) and can have slightly tighter qualifying guidelines.

If you can keep your loan under $726,200 by either putting enough down and/or keeping your sales price low enough, you will be rewarded with a lower interest rate and payment.

Loans above $861,350 in Sonoma County would be considered a jumbo loan.  Big banks and credit unions tend to have the most competitive rates on jumbo loans.  As a mortgage broker, we are most competitive on conforming loans.

Having said this, as a mortgage broker, we can offer jumbo loans with easier qualifying guidelines, and we have the ability to close jumbo loans in as little as 15 days.  Most big banks and credit unions have difficulty closing that quickly, and their guidelines will certainly be tighter. (lower debt-to-income ratio requirements, higher reserve requirements…etc.)

We are able to lend on 2-4 unit properties as well.  Here are the conforming loan limits for multi-unit properties in Sonoma County…


  • 2-unit property – $1,102,700
  • 3-unit property – $1,332,900
  • 4-unit property – $1,656,450
