'What's my home worth?' is the most important question in real estate — and it's also the most misunderstood. If Zillow has ever told you your home is worth $850,000 and a neighbor just sold a nearly identical home for $780,000, you know exactly what I mean.
I'm Tammy Petit Loveland at Meridian Group Real Estate, and today I'm going to break down exactly how we determine the real market value of a Castle Rock home — and why that process is so different from an algorithm.
What a Zestimate Is (And Isn't)
Zillow's Zestimate is an algorithm based on publicly available data — tax records, MLS history, square footage. It doesn't know that your kitchen was fully renovated last year. It doesn't know that the street behind you has a noise issue. It doesn't know that your specific street in The Meadows backs to a trail that adds a $40K–$60K premium to your view.
For a rough ballpark, Zestimates can be useful. For a pricing decision that affects hundreds of thousands of dollars — they're not enough.
How I Calculate Your Home's Value: The CMA
A Comparative Market Analysis (CMA) is the professional standard for home valuation. Here's what goes into it:
-
Recent comparable sales within a 1-mile radius, typically within the last 90 days
-
Active competing listings that your home will be priced against
-
Pending sales to understand where the market is heading
-
Adjustments for square footage, lot size, condition, upgrades, view, and location within the neighborhood
-
Market velocity — how quickly homes are selling in your specific price tier
I've done hundreds of these CMAs in Castle Rock and Castle Pines. The local knowledge that informs those adjustments is something no algorithm can replicate.
