Atherton jumbo loans and 2026 loan limits.

Atherton is a small, almost entirely residential town. El Camino Real and the Caltrain line cross it, Middlefield Road runs through its eastern part, and Alameda de las Pulgas through its western part. Redwood City is to the north and Menlo Park to the south and east. Holbrook-Palmer Park, a former estate, is the town’s park, and there is no shopping district inside the town limits.

The town’s zoning calls for large lots, generally an acre or more in most of the town, and single-family houses. So the typical property is a house set back from the road behind trees and a gate, often with a guest house, a pool house or other buildings. Many streets have no sidewalks, and the town protects its large old oaks and other heritage trees, which affects where and what an owner can build.

The appraisal above all, then how the buyer’s income and assets are documented. Large individual properties are hard to compare.

An appraiser needs recent sales of similar homes, and in a small town of large lots there may be few in any one year. The appraisal can take longer, the appraiser may look to neighboring towns, and on a larger jumbo loan a lender may order a second appraisal. Guest houses and other buildings are valued when they were built with permits. A permitted accessory dwelling unit is counted in the value, and the property is still measured against the one-unit limit.

On the income side, stock takes the most reading: restricted stock units, shares from a company that has gone public, or equity in a private company. Lenders generally count vested stock income that has a history, treat shares you have sold as assets once the sale is documented, and do not count private-company stock. Timing around a vesting date or a lockup can change what a lender will count, so go through the calendar with Sam before you make an offer.

Lindenwood is in the northeast part of Atherton, east of Middlefield Road, behind the long brick wall that runs beside that road. It stands on the grounds of a nineteenth-century estate, and the estate’s old gates still mark the entrance on Middlefield Road. Inside, the streets curve past mature trees, with names such as Linden Avenue, James Avenue and Flood Circle.

Lots are mostly about an acre and fairly level, and the houses are single-family homes, built over the decades after the estate was subdivided, beginning in the late 1930s, and a good number replaced since with larger new ones. A block can therefore hold an original ranch house and a recent house several times its size. For an appraisal that matters: the appraiser looks for sales of similar size and age inside Lindenwood first, and in a given year there may be only a handful. Expect the appraisal to take longer, and a second one on a larger loan. There is a neighborhood association, so ask whether any dues apply. Heritage trees on a lot can limit where a new house or an addition may go, so ask the town before you plan to rebuild.

West Atherton is the part of town west of El Camino Real, running toward Alameda de las Pulgas. Atherton Avenue is its main street, crossed by Selby Lane, Elena Avenue and others, and the Menlo Circus Club, a private club with stables and polo, is on Park Lane. Further west, past the Alameda, the ground begins to rise toward the hills.

This is where many of the town’s largest lots are found, some well over an acre, with long driveways and houses that cannot be seen from the road. Properties often include a guest house, a pool house, a tennis court or a separate garage building. For a lender, the questions follow from that. The appraisal has few close matches and may take longer, a second appraisal is common on larger loans, and every building should have permits to be counted. If the plan is to tear down and build new, a purchase loan is not the right tool, and a construction loan reviews the plans, the builder and the budget. On the slopes west of the Alameda, check the address on the state’s fire hazard map and ask for an insurance quote early.
