"Check your county" is filler advice in most states. In California it is the question that decides which rulebook your buyout is underwritten against.

Parsed from the FHFA conforming-loan-limit data county file rather than read from a summary.
★★★ Why this is not a trivia question in a divorce
Everything on this site about how a buyout is classified, limited cash-out rather than cash-out, the twelve-month condition, the written-agreement condition, the "no waiting period" on-title exception, comes from the Fannie Mae Selling Guide. Those are agency rules, and they govern loans delivered to Fannie Mae.
★★★ Above your county's limit, the loan is jumbo. It is priced and underwritten by investor overlays, and the agency buyout provisions do not apply to it. The protective rule at the centre of this site has a ceiling, and the ceiling is a county line. The rule that stops there.
★★ So in California the sequence is: find the county limit, compare it to the loan the buyout actually needs, and only then talk about how the transaction will be treated.
★★ The spread is the point
$832,750 in 41 counties. $1,249,125 in 10. That is a difference of over four hundred thousand dollars in what can be done inside agency rules, between counties that in places share a border.
★★ Seven counties sit in between, from $897,000 in Sonoma to $1,104,000 in San Diego. ★ For comparison, every other state in this network has exactly one figure statewide. California is the reason the advice exists.
★★★ And one metro where even the ceiling is not enough
Santa Clara County carries the highest limit in the country at $1,249,125. The typical San Jose home is $1,527,731.
★★★ So in Silicon Valley the typical house is above the highest conforming limit. A buyout there starts as a jumbo transaction by default. What that changes about the conversation.
Multi-unit
The figures above are one-unit limits. Two-, three- and four-unit properties carry higher limits in the same FHFA file. California divorces involve duplexes and small multi-unit buildings more often than most states, so ask and we will pull your county's full set.
★ What actually decides a California buyout file
- ★★ The loan amount against your county limit: agency or jumbo.
- ★★ The deed date, for the twelve-month joint-ownership condition. Why it is measured to disbursement
- ★★ The agreement, and whether it covers the disposition of proceeds. What it must say
- ★★★ The assessed value, not the market value, because Prop 13 survives the transfer and the escrow follows the assessment. The statute
- Income against the payment, on one income rather than two.

Frequently asked questions
What is the conforming loan limit in California for 2026?
It varies by county. California has nine distinct one-unit limits across its fifty-eight counties: ten counties including Los Angeles, San Francisco, Santa Clara and Orange are at the national ceiling of $1,249,125, forty-one counties are at the $832,750 baseline, and seven sit on intermediate tiers from $897,000 in Sonoma to $1,104,000 in San Diego.Why does the county loan limit matter in a divorce buyout?
Because the rules that make a buyout a limited cash-out refinance rather than a cash-out come from the Fannie Mae Selling Guide and govern loans delivered to Fannie Mae. Above the county limit the transaction is jumbo, priced by investor overlays, and those agency buyout provisions do not apply.Which California counties have the highest loan limit?
Ten counties carry the national ceiling of $1,249,125 for 2026: Alameda, Contra Costa, Los Angeles, Marin, Orange, San Benito, San Francisco, San Mateo, Santa Clara and Santa Cruz.Mike Certo · NMLS #260555 · Cornerstone First Mortgage NMLS #173855 · Equal Housing Lender.
