6 Real Estate Tips for Hillsborough, Burlingame and San Mateo

Most real estate advice treats the Peninsula as one market. It isn't. As of October 2026, Hillsborough and Burlingame sit a few minutes apart yet the numbers point to different approaches for buyers and sellers. San Mateo adds a third layer, where the neighborhood and the age of the house often matter more than the citywide numbers.

After more than five decades working in these communities, and with a lifelong interest in architecture and construction, I've come to think the best strategy starts with matching your tactics to the market in front of you. Here is how I'd approach it this fall.

1. Read the sale-to-list ratio before you read the list price

The single most useful number for a buyer or seller right now is how close homes sell to their asking price. As of October 2026, Hillsborough homes averaged 98.7% of asking price, while Burlingame homes averaged 104.6%.

Those two figures call for different strategies. In Burlingame, a list price is closer to an invitation to bid. If you are shopping there, expect that a well-priced home may sell above asking, and treat the list price as a floor for planning, not a target. Talk with your lender and your agent about how much room to build into your budget.

In Hillsborough, a price near list is the realistic ceiling for most transactions. Buyers have room to negotiate on terms, timing, and sometimes price. Sellers should assume the market will test their number rather than bid it up.

There is a second Hillsborough figure worth reading carefully. The average list price in October was $11.74 million, while the average sale price was $8.60 million. Those averages don't describe the same homes, so I wouldn't read the gap as a discount on any one property. I read it as a caution. With a 98.7% sale-to-list ratio, overpricing a luxury property may still reduce your negotiating leverage, so price with recent sales in mind.

2. Sellers: price to the first 23 days

Hillsborough homes averaged about 23 days on market in October 2026. Inventory was tight, with 16 active listings compared with 21 a year earlier, and roughly 1.6 months of supply. Only 5 new listings came on during the month, down 76.2% year over year.

On paper, that is a seller's setup. In practice, scarcity only helps you if the price is credible. The first few weeks bring the most attention from serious buyers and their agents. If the number doesn't hold up to their comparables, they move on quietly, and a price reduction a month later reads as weakness rather than flexibility.

My advice is simple. Set the price from recent closed sales, not from what a neighbor is asking. An aspirational list price down the street tells you what someone hopes to get. A closed sale tells you what a buyer actually paid.

This matters in any part of Hillsborough, including the estates around the Carolands Chateau. Where comparable sales are harder to find, the temptation is to price on feeling. That is exactly when disciplined pricing earns its keep, because there is less market evidence to rescue an overreach.

3. Buyers in Burlingame: get your offer ready before the tour

With Burlingame homes selling at an average of 104.6% of asking and active listings down to 24 from 29 a year earlier, the window to act on a good house is short. Buyers who start preparing after the open house are usually a step behind.

Before you tour anything in Burlingame, I'd have three things settled:

• Financing. A full underwrite or a strong pre-approval, with your lender ready to issue an updated letter for a specific price on short notice.
• Inspection plan. Know whether you'll rely on the seller's disclosure package and reports, order your own inspection before offering, or keep a contingency. Line up your inspector in advance either way.
• A walk-away number. Decide your true maximum before emotion enters the room. Write it down.

Then decide in advance which contingencies you can shorten and which you cannot. A buyer with a large down payment might comfortably shorten the loan contingency. Someone stretching on the appraisal may need to keep that protection. Knowing your answers ahead of time lets you write a clean offer within a day, which often matters as much as the price itself in a market running above list.

4. Judge the house like a builder, not just a buyer

My interest in architecture and construction shapes how I walk through a house. Fresh paint, new fixtures, and good staging are pleasant. They are also the cheapest things to change. What deserves your attention first are the bones.

In order, I look at:

• Foundation. Cracks, uneven floors, and sticking doors can point to settlement.
• Drainage. Where water goes during a winter storm matters more than almost anything else on a hillside or older lot.
• Roof. Age, material, and remaining life.
• Electrical and panel capacity. Older panels may not support modern loads like EV charging or heat pumps without an upgrade.
• Sewer lateral. An older line can fail inspection or need replacement, and the cost lands on the owner.

Any one of these can quietly become a six-figure problem, and stylish staging won't show it to you.

This is especially relevant in San Mateo's older neighborhoods. Baywood, a 1920s garden suburb beside Downtown San Mateo, Aragon with its storybook homes on tree-lined streets, and San Mateo Park with its early 20th-century homes in a park-like setting all offer real period character. That character comes with age-related due diligence. Ask for permits on any additions, remodels, or converted spaces, and confirm the work was finaled and done to code. An unpermitted addition can affect your insurance, your appraisal, and your eventual resale.

5. Use the 7.40% rate as a negotiating variable, not just a cost

The average 30-year fixed rate was 7.40% the week of October 15, 2026, with the 15-year at 6.71%. Most buyers treat the rate as a fixed cost. I'd treat it as something to negotiate around.

This works best in Hillsborough, where homes are selling at 98.7% of list and sellers have less leverage than in Burlingame. When a seller won't move on price, ask instead for a credit you can apply toward a rate buydown or closing costs. Lenders typically price a permanent buydown in points, where one point equals 1% of the loan amount. On a $2,000,000 loan, that is $20,000 per point. A temporary buydown, which lowers the rate for the first year or two, is often less expensive and can be funded by a seller credit. Your lender can quote the exact cost and how much it lowers the rate.

Why a credit rather than a price cut? A modest price reduction barely changes the monthly cost of a large loan. The same dollars applied to the rate can have a more noticeable effect in the early years, and sellers sometimes find a credit easier to accept because the headline price stays intact.

You may also plan to refinance later. That can be a sensible strategy, but I'd never build a purchase around it. Rates may fall, hold, or rise, and no one can promise which. Buy a home you can carry at today's rate, and treat any future refinance as a bonus rather than a requirement.

6. Look beyond the town line for land and building

With only 5 new Hillsborough listings in October and inventory tight across the area, some buyers and investors are widening their search to land, where they can build or simply hold. That can make sense, but land is valued very differently from a finished home.

Acreage alone tells you little. What determines value is usability: slope, access, utilities, zoning, and setbacks. A gently sloped lot with water, power, and sewer or septic approval at the street can be worth far more than a larger parcel that needs a long driveway, retaining walls, or extended utility runs.

Before bidding, confirm what can actually be built. Talk with the planning department, review zoning and setback rules, and get preliminary estimates for permits, utility connections, and site work. Those costs can be substantial, and they belong in your offer price from day one.

Woodside is one place to see these considerations at work. The 1-acre parcel at 45 Mission Trail Road, listed at $6,495,000, is an example of a land purchase where the analysis starts with the site rather than a floor plan. Whether you're evaluating that lot or any other, the questions are the same: what the land allows, what it will cost to get there, and whether the finished result justifies both.

The common thread across all six tips is that the numbers and the house each tell part of the story. Hillsborough's 98.7% and Burlingame's 104.6% describe the market's mood. The foundation, the permits, and the site describe the asset. The strongest decisions come from reading both, because a fair price on a house with sound bones will hold its value long after this season's statistics have changed.
