It's the question I'm asked more than any other: "Monica, what's my home actually worth?" And almost every time, the person asking has already typed their address into a website and gotten a number. Here's the problem - on the Westside, at the price points I work in, that number is often wrong by a margin that would shock you. Sometimes it's off by hundreds of thousands of dollars. On a trophy property, it can be off by millions.
So let me explain how luxury home valuation really works here, why the algorithms struggle with our market, and what actually determines what your Pacific Palisades, Malibu, Santa Monica, Brentwood, Venice, or Marina del Rey home will sell for in 2026.
Three ways a home gets valued
Not all "values" are the same thing, and confusing them is where sellers go wrong:
The automated estimate (AVM). This is your Zillow Zestimate or Redfin estimate - a computer model that pulls recent nearby sales and tax records. It's instant, it's free, and on a cookie-cutter tract home it can be reasonably close. On a unique luxury home, it's a starting point at best.
The appraisal. A licensed appraiser produces this, usually for a lender once you're in escrow. It's a formal, defensible number based on comparable sales - but it's backward-looking and conservative by design, because its job is to protect the bank, not to find your home's ceiling.
The agent's valuation (a comparative market analysis, or broker opinion of value). This is what I do. It combines the data the algorithms use with the things they can't see: the off-market sales I know about, the quality of a renovation, the exact view from the primary suite, and where buyer demand is actually heading. It's the number that's tied to what a real buyer will pay.
Why luxury Westside homes break the algorithms
The automated models fail at the high end for specific, structural reasons - and once you understand them, you'll never trust a Zestimate on a $5 million home again:
There aren't enough comparable sales. Algorithms need recent, similar sales nearby. A custom Malibu architectural on a bluff may have no true comp - nothing else like it sold this year. The model fills that gap with bad math.
The best sales are invisible to the models. A meaningful share of luxury Westside deals happen off-market and never feed the public data the algorithms rely on. I know about those sales because I'm in the network where they happen. A computer isn't.
View, lot, and land carry enormous, uneven premiums. Two homes of identical square footage can differ by millions based on a whitewater view versus a partial peek, a flat usable lot versus a slope, or proximity to the sand. Models flatten what the market prices steeply.
Renovation quality is invisible to a database. A gut-renovated home and a tired original with the same beds and baths look identical to an algorithm and completely different to a buyer.
What actually moves value on the Westside
When I value your home, here's what I'm really weighing:
Location down to the street and block - not just the city or ZIP.
View and orientation - ocean, canyon, city, or none, and how it reads from the main living spaces.
Lot - size, usability, privacy, and whether it can be expanded or rebuilt.
Condition and finish level - the difference between move-in-perfect and a project.
Land value itself - which, in parts of the Palisades especially, has become its own conversation since the fire.
Ownership structure - in Marina del Rey, whether a property is fee simple or leasehold materially changes value.
The post-fire wrinkle
I have to flag this honestly, because it's distorting valuations right now. The January 2025 Palisades Fire scrambled the comp data on the upper Westside. In and around the burn area, you're often valuing land plus rebuild potential rather than an existing house, and the few recent sales can be skewed by distressed situations or investor lot purchases. Plug a Palisades address into a website today and the estimate may be close to meaningless. This is exactly the kind of market where you want a human who has tracked it sale by sale - which is what I do. For context on that market, my notes on Pacific Palisades after the fire are a good companion read.
How I value your home
My process is simple, and it's free:
I pull every relevant comp - including the off-market ones the public sites can't see.
I walk the home in person. I cannot value a view, a finish level, or a floor plan from a screen, and I won't pretend to.
I give you a range and a recommendation, with a pricing strategy attached - because the right list price depends on your goal, your timeline, and current demand, not just a single number.
I tell you the truth, even when it's not the number you hoped for. Overpricing a luxury home is how it sits unsold and stale. I'd rather price it to actually sell.
Let's talk

Frequently Asked Questions
How accurate are online home value estimates like Zillow?
On a standard tract home they can be reasonably close, but on a unique luxury Westside property they're often off by hundreds of thousands - sometimes millions. The models lack comparable sales for one-of-a-kind homes, can't see off-market deals, and can't judge view, lot, or finish quality.
How do you value a luxury home when there are no comparable sales?
I rely on the closest available comps, the off-market sales I have visibility into through my network, and a hands-on read of the home's view, lot, condition, and finishes. For truly unique properties, valuation is as much judgment and market knowledge as it is data.
What's the difference between an appraisal and an agent's valuation?
An appraisal is a formal, conservative, backward-looking number prepared for a lender to protect the loan. My valuation is a market-driven estimate of what a real buyer will pay, built from current comps - including off-market ones - and an in-person read of the home. They answer different questions.
How did the Palisades Fire affect home values on the Westside?
In and near the burn area, many properties are now valued as land plus rebuild potential rather than as existing homes, and the limited recent sales can be skewed by distressed or investor transactions. Online estimates are especially unreliable there, which makes hands-on valuation more important than ever.
How often should I get my home valued?
If you're considering a sale, get a fresh valuation - the market moves, and a number from a year ago may be stale. Even if you're not selling soon, a periodic check is smart for refinancing, estate planning, or simply understanding your largest asset.
What adds the most value to a Westside home?
View, location, and a usable lot carry the steepest premiums here, followed by a high-quality, current renovation. The same square footage can be worth dramatically more or less depending on those factors, which is why a database-driven estimate so often misses.
