A Healdsburg local, focused on getting Sonoma County buyers to the closing table.
CJ Kerls has worked in mortgage lending for 35+ years. He bought his Healdsburg house in 2006 as a second home and relocated to Sonoma County full time later. He and his daughter and loan partner, Chelsea, finance homes throughout Sonoma County, from first purchases in Santa Rosa and Rohnert Park to rural properties, second homes and wine-country estates.
The important local distinction is that Sonoma County is not one uniform housing market. Price, property type, insurance, intended occupancy and even the available appraisal comparables can change substantially from one town to the next. Those details often determine the right loan structure before the interest rate becomes the deciding question.
The right mortgage strategy in Sonoma County often depends on the town, the property and the proposed loan amount. Here is where the financing questions tend to change.
Healdsburg is where CJ lives and the market he knows best. Prices frequently place loans near or above Sonoma County's $897,000 conforming limit, although the down payment can sometimes keep a purchase within conforming financing. Second-home buyers and borrowers with business income, partnership distributions or substantial assets may need jumbo, bank-statement or asset-based underwriting. The important step is to compare structures instead of assuming jumbo is automatically worse. Read more about jumbo and super-jumbo loans, conforming, high-balance and jumbo financing, and mortgage options beyond tax returns.
Santa Rosa has the county's broadest range of housing and price points. Condos and more moderately priced neighborhoods create opportunities for conventional, FHA and first-time-buyer financing, while larger homes in Fountaingrove and Bennett Valley may require high-balance or jumbo loans. Homes rebuilt after the 2017 fires offer newer construction on established lots, but that does not guarantee inexpensive coverage. The actual premium becomes part of the qualifying payment, so investigate it early. See why insurance can change mortgage qualification.
Sonoma Valley contains several markets. The City of Sonoma and the Springs corridor include primary residences and second homes across a wide range of prices. Glen Ellen and Kenwood are smaller and more rural, with a greater likelihood of acreage, guest structures, wells, septic systems and limited appraisal comparables. Higher-priced purchases may require jumbo financing. Occupancy should be established at the beginning because a genuine second home and a property operated as a rental follow different rules. See the guide to vacation-rental mortgages and cost segregation.
Petaluma's South County location and SMART connection to Larkspur attract buyers who still work elsewhere in the Bay Area. Many purchases land near the conforming limit, so the down payment can move a loan among conforming, high-balance and jumbo options. The west side includes older and historic properties; the east side has more recent construction. Legal duplexes and accessory units may create rental-income opportunities, subject to unit, tenancy and appraisal review. See the two-unit first-time-buyer guide and how RSU income is counted.
Windsor is predominantly an owner-occupied, detached-home market with more recent construction than many Sonoma County communities. Conventional and high-balance financing do much of the work, while FHA and low-down-payment programs may fit the lower end. Standardized housing can make appraisal easier, but buyers should still identify HOA obligations, leased solar, PACE assessments, insurance and deferred maintenance early.
Rohnert Park is one of the county's more attainable markets, with meaningful condo and townhome inventory and a substantial first-time-buyer segment. Cotati is smaller and more varied, combining detached and attached housing near Sonoma State. For a condominium, the lender reviews the project as well as the unit. Insurance, reserves, litigation or deferred maintenance can affect eligibility. A home marketed as a townhome may legally be a condominium or planned-unit development, so confirm the distinction early.
Sebastopol is a higher-priced lifestyle market; Graton, Forestville, Occidental and the surrounding countryside span more prices and property types. Outside incorporated areas, financing may involve acreage, private roads, wells, septic systems, outbuildings, agricultural zoning or incomplete permit histories. The appraiser must determine whether comparable sales support those features. Water, septic, access, insurance and secondary structures should be reviewed early. In much of West County, insurance can matter as much as the mortgage rate.
Guerneville, Monte Rio and nearby Russian River communities can offer lower entry prices, but cabins, private roads, wells, septic systems and flood exposure may complicate financing. Updated federal flood maps and related county zoning changes make flood-insurance requirements address- and structure-specific. Bodega Bay, Jenner and the coast form a different, often higher-priced second-home and investment market with coastal exposure and limited comparables. Rental use must be verified parcel by parcel. Some zoning permits expire upon transfer, while use permits may be treated differently. DSCR financing may use supported rental potential when the use is legal and the lender accepts the rent analysis. Read about financing a permitted vacation rental.
Cloverdale is one of Sonoma County's more attainable detached-home markets, where conventional, FHA and low-down-payment financing may be realistic. Rural-edge properties can still introduce well, septic, acreage and insurance questions. Geyserville is a small, thinly traded market with rural estates, vineyard properties and few comparable sales. The communities are close, but a Cloverdale subdivision purchase and a Geyserville estate may require very different appraisal and loan strategies.
Yes. CJ originates mortgages throughout Sonoma County, including Santa Rosa, Healdsburg, Petaluma, Sonoma, Windsor, Rohnert Park, Cotati, Sebastopol, Cloverdale, the Russian River, the Sonoma Coast and the surrounding rural communities.
For a one-unit property, the Federal Housing Finance Agency sets Sonoma County's 2026 conforming loan limit at $897,000. A conventional first mortgage above that amount is outside conforming limits and will generally require jumbo financing or a different structure. The limit applies to the loan, not the purchase price.
Loans between the national baseline and the Sonoma County limit are called high-balance conforming loans, and some borrowers in that range can compare both high-balance and jumbo execution. See the jumbo loan faq and the conforming, high-balance and jumbo comparison.
For 2026, the FHA loan limit for a one-unit property in Sonoma County is $897,000. HUD's FHA Mortgage Limits Lookup lists Sonoma County as a high-cost area, with a limit above the national FHA floor but below the national ceiling. The FHA figure happens to match the county's one-unit conforming limit for 2026, although FHA and conforming limits are established under different systems.
If the required loan amount is above $897,000, FHA financing is not available. The buyer would generally need jumbo conventional financing, a larger down payment or another structure. Our jumbo and super-jumbo guide explains what changes when a loan moves outside conforming limits.
Yes. The lender includes homeowners insurance in the monthly housing expense used to calculate debt-to-income. A premium that comes in higher than estimated can reduce borrowing capacity or require the loan to be restructured.
Some properties may need a California FAIR Plan fire policy paired with supplemental coverage. Obtain an address-specific quote early and bring the complete premium back to CJ before relying on a final pre-approval amount. Read Insurance Is the New Interest Rate for a detailed example.
Potentially. Conventional underwriting may still be the best option, but some borrowers can also be evaluated through bank deposits, a profit-and-loss statement, eligible assets or other program-specific documentation.
These alternatives have different pricing, down-payment and reserve requirements and are not a way to avoid documenting the ability to repay. CJ compares the available approaches against the borrower's actual business and financial profile. See six mortgage options for self-employed borrowers.
A second home must be a one-unit property the borrower occupies for part of the year and keeps under the borrower's control. Rental income from that home generally cannot be used to qualify. An investment property is underwritten and priced as a rental, and eligible rental income may be considered under the applicable program.
Occasional renting does not automatically turn every second home into an investment property, but intended use, management arrangements and lender overlays matter. The occupancy selected on the application must match the real plan for the property. Tax treatment is a separate question for a qualified tax adviser. See the vacation-rental mortgage guide.
Possibly. FEMA's final updated flood maps for Sonoma County, including the Russian River watershed, became effective July 31, 2024. Sonoma County continued aligning its local floodway and floodplain zoning with those federal maps into 2025. If the lender determines that the insured structure is in a Special Flood Hazard Area, flood insurance will generally be required.
The answer is property-specific, so buyers should check the address using the FEMA Flood Map Service Center and confirm the lender's determination rather than relying on a general description of the neighborhood.
Some investment-property and DSCR programs can use an appraiser-supported market-rent analysis or another lender-approved method to evaluate short-term-rental potential. It is not automatic.
The intended rental use must be lawful, the property must satisfy the lender's eligibility rules, and Sonoma County permits and caps must be checked for the individual parcel. A zoning permit may expire when a property transfers, while a use permit may run with the land. Confirm legal eligibility before relying on projected income.
Yes. Qualified buyers may have access to conventional low-down-payment, FHA, CalHFA or other assistance options, subject to current program rules and available funding.
An owner-occupied two- to four-unit property can also allow eligible rent from the other units to be considered in qualification. Legal unit count, existing leases, appraisal rents and required reserves all matter. Read the two-unit first-time-buyer guide.
Yes. CJ works with physicians and other medical professionals relocating to Sonoma County employers. Physician-mortgage terms vary by lender and can change, so the appropriate down payment, maximum loan amount, reserve requirement and treatment of future employment should be confirmed for the individual borrower rather than quoted as a permanent countywide rule.
