Construction Loans in Atherton
What's the difference between construction loans and purchase mortgages?
Construction loans disburse in phases as the home is built. Purchase loans close once at the end. Construction also charges interest-only during the build; purchase loans include principal and interest from day one.

03
Construction lending in California is more specialized than standard purchase mortgages. Lenders must manage draw schedules, inspector sign-offs, and the transition from construction to permanent financing.
Retail banks and mortgage brokers both offer construction programs, but the underwriting is stricter and timelines longer. Plan for 45 to 60 days from application to first draw, with ongoing inspections throughout the build.
04
Construction loans make sense in Atherton when you're building a custom home that will exceed the conforming limit of $1,249,125. The 2026 limit is firm, so jumbo construction financing is common here.
For properties under the conforming limit, a standard construction-to-permanent loan keeps costs down. Above that threshold, jumbo construction programs offer flexibility but demand stronger reserves and credit.
05
Construction loans differ from standard purchase mortgages in timing and cost structure. A purchase loan closes once; a construction loan disburses in phases and converts to permanent financing at completion.
If you're buying an existing home in Atherton, a standard mortgage closes in 30 days. Building new means 12 to 18 months of construction draws, inspections, and then the permanent loan conversion.
06
San Mateo County school districts placed bond measures on the June ballot to fund facility improvements. That kind of public investment in schools and infrastructure supports long-term property values for new construction in the area.
The Bespoke mixed-use development at the former Talbot's site in San Mateo shows downtown revitalization momentum. Infrastructure projects like this one strengthen the broader county market for custom home builders and buyers.
07
Construction lending in California has grown as homeowners seek custom builds in high-value markets like Atherton. Proposed federal legislation to allow Fannie Mae and Freddie Mac to securitize construction loans could expand availability and lower costs.
Current construction lending remains concentrated among portfolio lenders and jumbo specialists. Conforming construction programs exist but are less common than jumbo options in the Atherton price range.
