Palo Alto jumbo loans and 2026 loan limits.

Palo Alto stretches from the marshes of San Francisco Bay to the foothills of the Santa Cruz Mountains. The Bayshore Freeway runs along its bay side and Interstate 280 through its hills, with El Camino Real, the Caltrain line and Alma Street between them. Downtown is on University Avenue, which leads to the Stanford campus, and a second shopping street runs along California Avenue. San Francisquito Creek is the northern boundary.

North of Oregon Expressway the neighborhoods are older, with houses from the early 1900s onward on tree-lined streets. South Palo Alto has many mid-century modern tract houses, a number of them in neighborhoods where the city limits houses to a single story. There are condominiums and townhouses near downtown, California Avenue and El Camino Real, and larger properties in the foothills.

How your income is paid, the flood map, and any city rules that limit what can be changed on the lot.

Pay in stock has its own rules. Lenders generally count vested restricted stock units when there is a history of receiving them and more are due to vest, and they treat shares from a purchase plan or exercised options as assets, not income. Stock in a private company usually cannot be counted. A new job, a first vesting date or the end of a lockup can each change the picture, so timing matters.

Parts of the city near San Francisquito Creek and toward the bay are in flood zones on FEMA’s maps. When a financed home is in one, the lender requires flood insurance, and its cost is counted with the other housing costs. Look up the address before you make an offer.

City rules can shape a purchase too. Some neighborhoods are historic districts, and some allow only single-story houses, which matters if the plan is to enlarge or rebuild. A permitted accessory dwelling unit is counted by the appraiser. With a condominium the lender also reviews the homeowners association.

Old Palo Alto is the neighborhood between Alma Street and Middlefield Road, from Embarcadero Road south to Oregon Expressway. The Caltrain line runs along its western edge beside Alma Street, and the streets, among them Waverley, Cowper, Bryant and Santa Rita, form a regular grid shaded by large trees. Gamble Garden, a public garden, is on its northern edge, by Embarcadero Road.

The homes are single-family houses on lots that are wide for Palo Alto, some of them double lots. Houses date from the early 1900s to the present, in many styles, and a number have been rebuilt at a much larger size. That range is the main thing for an appraisal: the appraiser looks for sales of similar size, age and lot, and on a larger jumbo loan a lender may order a second appraisal. The ground is level and there is no homeowners association. Some older houses are on the city’s historic list, which can limit changes to the outside, so ask before you plan a remodel. A basement, a guest house or an accessory dwelling unit counts toward value when it has permits.

Professorville is a small historic district just south of downtown Palo Alto, centered on Kingsley, Lincoln and Addison avenues between about Ramona and Cowper streets. Its name comes from the faculty houses built here in the 1890s and early 1900s, soon after the university opened. The district is listed on the National Register of Historic Places.

The homes are mostly brown-shingle and Craftsman houses on lots of many sizes, along with some later ones. Because this is a historic district, the city reviews changes to the outside of a house, and tearing one down is far harder than elsewhere. That does not change the kind of loan, but it matters to the plan: a buyer who means to rebuild or greatly enlarge should ask the city first. Older houses can also bring questions in an appraisal or inspection about foundations, wiring and work done without permits. Lenders treat a renovation differently from a purchase, and OriginPoint lists renovation loans among its programs, so ask Sam what applies. The loan limit is Santa Clara County’s, the same as in the rest of the city.

Crescent Park is the neighborhood northeast of downtown Palo Alto, east of Middlefield Road, with San Francisquito Creek and Woodland Avenue along its northern and eastern sides and Channing Avenue to the south. University Avenue runs through the middle of it on the way to the freeway, and Eleanor Pardee Park is at its southern edge. Hamilton Avenue and Crescent Drive are among its streets.

Homes are single-family houses on large lots, many dating from the 1920s and 1930s, with newer houses among them. The creek is the fact to know. The streets nearest San Francisquito Creek flooded in 1998, and parts of the neighborhood are in a flood zone on FEMA’s maps. A lender requires flood insurance on a financed home in a mapped flood zone, and the cost of the policy is counted in the monthly housing cost, so look up the address and ask for a quote early. Flood-zone rules can also affect a rebuild, including whether a basement is allowed. Otherwise the review is the usual one for a large individual house: an appraisal with few close matches, and possibly a second appraisal on a larger loan.
