1550 Old House Road

Pasadena, CA 91107

Pending, $1,645,000

3 beds, 2 baths, 1,899 sq ft living area, 0.46 acre lot, built 1953

This quintessential California Ranch-style home, tucked on a quiet cul-de-sac just a stone's throw from Eaton Canyon Golf Course, captures the ease and optimism of California living. Beautifully sited on nearly half an acre, the home was designed during a period of American architecture when indoor-outdoor living was paramount and everything simply seemed to make sense. Mature landscaping creates a wonderful sense of privacy while framing the inviting front porch, where weathered brick and a traditional red front door lend warmth and character. Beyond the front door, a proper entry with coat closet opens to the living room and dining area. The living room features original panel moldings, a stately fireplace with rich green marble surround, and warm oak floors that continue throughout the home. The dining area opens naturally to the den, creating an easy gathering space for modern everyday living. The den features a handsome raised brick fireplace that expands the seating area, while its asymmetrical design offers a subtle nod to the home's mid-century heritage. Two sets of updated French doors extend the room onto a broad deck overlooking the grounds. The adjacent kitchen is beautifully functional with generous cabinetry, a Viking range, and a large bay window overlooking the backyard. A connected laundry room provides additional storage and another convenient connection to the outdoors. Three bedrooms are thoughtfully situated together, including a spacious primary suite with substantial closet space and a remodeled full bath with double vanity. The two additional bedrooms share an updated, vintage-inspired hall bath with pedestal sink. Outside, the scale of the property truly reveals itself. Mature trees and established landscaping surround a sunny lawn, an arbor with climbing roses, a brick terrace, and multiple places to gather, dine, or simply enjoy the setting. A sizable driveway provides additional play and entertaining space and leads to a large detached two-car garage, once used as a workshop. Beyond, a terraced lower yard provides room to dream of a future ADU, pool, garden, or whatever comes next. With captivating curb appeal, an intuitive single-level floor plan, beautiful indoor-outdoor connections, and nearly half an acre of grounds, this is the kind of California home that feels as relevant today as when it was built.

Hyperlocal Property Analysis

One question matters when you're pricing a home to list, or weighing one to buy: at the price on the table, will it actually sell?

What you've just seen is a citywide analysis of this property, run through my proprietary Sell Odds engine. I built it because the industry has spent decades answering "what's it worth" without measuring the harder question. Sell Odds scores that against thousands of real closings and real failures in the same market. Learn more →

What you're looking at is the citywide layer. The hyperlocal layer analyzes your specific street, your specific tier, and the competition this property is up against. It runs on the same engine but isn't shown publicly, for two reasons.

The first reason is regulatory. Under CRMLS IDX and VOW rules, listings that didn't close (expired, withdrawn, canceled) cannot be shown to the public. They can only be shown to a consumer who has entered into a lawful broker-consumer relationship: personal non-commercial use, no scraping or redistribution, a bona fide interest in the transaction, acknowledgment of MLS ownership. It is enforceable and audited. That failed-listing data is what makes the hyperlocal layer possible, because failure is more than half the picture when you're scoring whether something will sell.

The second reason is analytical. Data alone isn't useful. The discipline applied to it is. Sell Odds runs on appraiser-grade discipline: sold and unsold outcomes only. Active listings are excluded because they are speculative. Pending listings are excluded because they have not closed. What's left is the only empirical record of what the market did and didn't pay. The engine took a year to build to run on that record alone. That's the analysis I walk through in person.

What the in-home analysis reveals:

Adaptive radius, by design. The hyperlocal analysis starts at one mile and expands to two only if the data is defensible enough to score with confidence, applying progressively stricter criteria the further out it has to reach. A mile crosses into different price tiers, different neighborhoods, different competition. Most agents lean on AI tools or CMA software that pulls a random set of properties by bedrooms, baths, and square footage, maybe filtered to a general area. That isn't analysis. That's a mailing list. Adaptive radius scoring is an appraiser's discipline. Agents are not trained in it.
Sell-through rate. None of the large platforms show you this number. It's the percentage of comparable listings that closed versus the ones that didn't. When it falls below sixty percent, more listings are failing than selling. The hyperlocal sell-through rarely matches the citywide. The gap is where the conversation begins.
Months of supply. How much inventory is competing with this property hyperlocally versus citywide. The citywide number averages everything out. The hyperlocal number tells you what's actually in your way. A property can show twelve months of citywide supply and four months hyperlocal. The delta is the leverage.
Price realization. The list-to-sale ratio across actual closings. A hyperlocal market closing at ninety-five percent of list operates very differently from a citywide one closing at eighty-nine. The hyperlocal number tells you where to position the asking price so it doesn't bleed equity through reductions.
Days on market. How fast comparable listings are moving locally versus citywide. Sellers hold the leverage when local days on market run tight. As they extend, that leverage starts moving to the buyer. The citywide number rarely shows either truth.

Four friction drivers, both citywide and hyperlocal, calculated live the moment we sit down. Nothing on Zillow, Redfin, Homes.com, or any other consumer site shows you any of this. Not the failed-listing data. Not the local-vs-citywide delta. Not the discipline. This is what consumer real estate analytics should have looked like a decade ago. Right now, it exists only in one place. Here.

SellOdds Real Estate Pricing Engine

v7.2

What This Score Represents

This is not an estimate of what your property is worth. It is the probability that your property will sell at its current price — derived entirely from what has actually happened to similar properties in your local market.

The SellOdds v7.2 engine analyzes every comparable sale and every comparable failure within your immediate area. Properties that closed. Properties that expired. Properties that were withdrawn or canceled. It measures where your price falls against that reality and returns a single, calibrated probability score — along with a full price elasticity curve showing how that probability shifts at every price point above and below.

When the score is high, the market data says properties like yours, priced like yours, are selling. When it drops, the data says they aren’t.

How It Is Different

Most pricing tools are automated valuation models — AVMs. They estimate a dollar value for a property based on tax records, public data, and regional averages. They tell you what a home might be worth. They do not tell you whether it will sell.

SellOdds v7.2 is not an AVM. It does not produce a valuation. It answers a fundamentally different question: at this price, what is the likelihood of a successful transaction?

Where traditional models rely on cached data refreshed on weekly or monthly cycles, this engine queries live MLS records at the moment of analysis. Where national platforms apply broad regional averages, this engine locks to your city, your property type, your size segment, and your quality tier. Where other tools treat a lakefront cabin and a fixer on a steep lot as interchangeable data points, this engine reads the listing narrative, classifies features individually, and measures their actual impact on sale outcomes.

There is no pre-trained model. No static index. No algorithmic estimate disconnected from what buyers are actually doing in your market right now.

What Data Powers It

Every calculation begins with live MLS data pulled directly from CRMLS — the largest MLS in the nation. Nothing is cached. Nothing is estimated from tax rolls or public records.

The engine identifies feature-matched comparables using structured MLS fields — bedrooms, bathrooms, living area, property type, geographic coordinates — and then goes further. It reads agent remarks to detect features that have no structured field: lake rights, lakefront access, walk-to-village proximity, remodeled kitchens, level lots, steep terrain, and dozens of other property characteristics that shape buyer behavior.

Comparables are filtered through multiple layers of data integrity checks. Non-residential properties, manufactured homes, vacant land, commercial listings, and lease agreements are excluded. Economically irrelevant outliers — properties so far from the subject’s price range that they would distort the analysis — are removed. Structural anomalies are identified and isolated. Only verified, habitable residential transactions that are genuinely comparable enter the scoring model.

The result is a clean, curated dataset of real outcomes — not a raw data dump averaged into a number.

Full empirical data — including comparable details, feature impact breakdowns, and market leverage analysis — is viewable once you sign in and agree to the VOW IDX compliance terms.

Why It Matters

Pricing a home is the most consequential decision in a real estate transaction. Price too high and the listing stalls — accumulating days on market, attracting lowball offers, and eventually expiring. Price too low and the seller leaves money on the table.

This engine gives agents and sellers something that dollar-value estimates cannot: a direct reading of market tolerance at a specific price point. The interactive price elasticity curve shows exactly how probability responds as price moves — not in theory, but based on the exposed outcomes of every comparable transaction in the local market.

The system also accounts for factors that static models ignore entirely. A property that failed to sell twice before carries that history into the analysis. Extended days on market are detected and reflected. Properties are compared within their own quality tier — an updated home is measured against other updated homes, not averaged against fixers. Size segments are analyzed independently because a 650-square-foot cabin and a 2,200-square-foot home operate in fundamentally different price-per-square-foot realities.

This is pricing intelligence grounded in what the market has actually done — not what an algorithm thinks it should do.

About the SellOdds Engine

SellOdds represents a fundamental shift in real estate pricing — focused on a single objective: translating live market outcomes into actionable pricing intelligence. Built for professionals, the engine is designed for use in listing presentations, pricing strategy sessions, and seller consultations.

The v7.2 engine incorporates dynamic market calibration, quality-tier-aware comparable analysis, feature-level impact measurement, hyperlocal geographic boundaries, and multi-layer data hygiene — all operating against real-time MLS data rather than cached snapshots or pre-computed indices.

SellOdds is not available as a consumer tool. However, Gregory Anderson — developer and proprietor of MountainCribs.com — has integrated the SellOdds engine into this platform as a buyer-facing, added-value feature, bringing professional-grade pricing intelligence directly to the property search experience.
