Los Altos jumbo loans and 2026 loan limits.

Los Altos became a city in 1952, on land that had been apricot orchards. Its downtown is a triangle of low buildings along Main Street and State Street. Foothill Expressway runs the length of the city, El Camino Real marks part of its northern edge, and San Antonio Road links the two. Smaller shopping districts sit at Loyola Corners and at Rancho. Adobe Creek and Permanente Creek cross the city on their way to the bay. Los Altos Hills, a separate town of much larger lots, lies to the west.

The typical home is a single-story ranch house on a lot of about a quarter acre, on a street with no sidewalk and plenty of trees. Many of those houses have been replaced by larger new ones, so old and new stand side by side. Condominiums and townhouses are found near downtown, along El Camino Real and on a few other streets.

On most files, how the buyer’s pay is made up. On the property, which house the appraiser is really valuing.

Salary, a yearly bonus and company shares are each counted differently. A lender generally wants to see that stock grants have been paid for some time and will continue, uses a cautious share price, and treats a one-time grant or sign-on bonus as savings, not income. Shares in a company that has not gone public are usually left out. Bring grant and vesting statements to the first conversation.

Many sales are of an older ranch house that the buyer plans to replace. The appraiser values what is there on the day, which may be mostly land. That is fine for a purchase loan, but the building work needs a construction loan or the buyer’s own funds.

Some pockets with a Los Altos address are outside the city limits, under Santa Clara County’s rules. Check which applies if you intend to build. Near the creeks, look up the address on FEMA’s flood map.

North Los Altos is the part of the city between downtown and El Camino Real, on both sides of San Antonio Road. It reaches toward the Palo Alto and Mountain View lines, and the downtown triangle, the civic center with its remnant apricot orchard, and the shops on El Camino Real are all within easy reach.

Lots here are mostly a little over a quarter acre, with smaller ones on the older streets off University Avenue, and the streets are shaded. Original ranch houses from the 1950s remain beside many large houses built since 2000. For an appraiser that split is the main task: a new house is compared with other new houses, and an original one with sales bought largely for the lot. On a larger loan, a second appraisal may be asked for. A number of condominium and townhouse groups stand along El Camino Real and near San Antonio Road. With those, the lender reviews the association and counts its dues, and the condominium limit is the same one-unit figure. A permitted accessory dwelling unit adds to value.

The Country Club area lies on the southwestern side of Los Altos, around the Los Altos Golf and Country Club, between Foothill Expressway and Interstate 280 near Loyola Corners. The ground rolls here, unlike the level center of the city, and the streets curve around the course and up toward the hills.

Homes are single houses on large lots, some with views across the fairways or toward the bay, built from the 1940s onward and frequently rebuilt. An important detail is jurisdiction. The club and most of the streets around it are outside the city limits, in an unincorporated pocket governed by Santa Clara County that the Census calls Loyola, although the mailing address is Los Altos. The loan limit is identical, since both are in the same county. What differs is who issues building permits and which rules on house size, trees and second units apply, so check the parcel before planning work. Sloping lots can bring appraisal notes on drainage and retaining walls. Houses vary widely, which means fewer close comparisons and sometimes a longer appraisal. Membership in the club is separate from any home purchase.

South Los Altos is the southern end of the city, on both sides of Fremont Avenue, reaching the Sunnyvale and Cupertino lines. Grant Road and Homestead Road are its main roads, and Highway 85 passes close to its eastern side.

This part was built a little later than the north, largely in the 1950s and 1960s, as tracts of ranch houses, with a group of mid-century modern Eichler houses among them and Craftsman and Mediterranean styles mixed in. Many houses have been extended or rebuilt. Because the tracts were built to a few patterns, an appraiser can generally find recent sales of similar homes nearby, and appraisals are usually direct. Loan sizes spread across the county limit: with more money down a loan can be conforming, and otherwise it is jumbo. If you are stretching to qualify, remember that a lender counts property tax at the new purchase price, not at the seller’s older, lower assessment. An addition or a converted garage should show up in the city’s permit record to be counted as living area.
