Free Home Valuation
How much is your home really worth?
Your Portland home's actual value comes from three things Zillow's algorithm can't see: what comparable homes have sold for on your specific block in the last few months, the condition and updates you've made to your home, and current market conditions in your neighborhood — inventory, days on market, and buyer demand. According to Zillow's own published Zestimate accuracy data, the median error rate on off-market homes is noticeably higher than on-market ones — enough that on a $700,000 Portland home the Zestimate can be off by tens of thousands of dollars. A proper Comparative Market Analysis (CMA) pulls five active, five pending, and five recently sold comparable properties from the live RMLS feed and layers in a real read of your neighborhood right now. Below: how a CMA differs from a Zestimate, the three factors that actually drive your home's value, and how to request a free CMA from Ross Seligman and the Own It Northwest team.
Portland Home Valuation
What is your Portland home actually worth?
Zestimates are a nationwide algorithm — they've never been to your home, never seen what you've updated, and don't know how your specific block is behaving right now. A real home value comes from three things a person has to actually look at: comparable sales in your immediate neighborhood, the condition of your home, and current market conditions on your specific street. That's what a Comparative Market Analysis (CMA) does — and it's what our team runs for every Portland homeowner who asks us to look.

What your home was listed for doesn't really matter. What matters is what it actually sold for. In a tight market, a comparable home may have sold for a lot more than list; in a slower market when interest rates are high, it may sell for a little less. Along with those comps, we're also looking at the neighborhood.
The way we get to an accurate number when we're valuing your home is through a CMA — a Comparative Market Analysis. It gives you an accurate snapshot of where your home's value stands today.
I'm Jim with Own It Northwest. Reach out anytime through the contact form and I'll take a look at your home, your neighborhood, the updates you've made, and give you a clear, accurate picture of where your home's value actually sits.
What three factors actually determine your home's value?
Comparable sales
What nearby homes have actually sold for in the last few months — not what they were listed for. In a tight market, comps often close above list; when rates are high, they may close below. Days on market for those comps tells us how motivated buyers are right now.
Condition of your home
A new roof, an updated kitchen, refreshed landscaping, or a full remodel each move the number in ways an algorithm can't see. Two homes on the same block with the same square footage can be $100,000+ apart based on condition and updates.
Current market conditions
Is inventory tight or building? Are homes sitting or moving fast? Is your specific neighborhood in a different rhythm than the metro average? These conditions can change month to month and matter more than any twelve-month trend line.
Why might the Zestimate be wrong about your home's value?
Zestimates work off a nationwide model that can't see the specifics of your street. Here's Jim on what actually goes into a real Portland home value.

Zestimates are nothing more than a nationwide algorithm. Zillow's never been to your home. They've never seen what you've done. They don't know anything about your neighborhood.
When we're putting together a value, we're really looking at three things.
First, comparable sales in your immediate area — what are homes actually selling for, and are they sitting on the market?
Second, the condition of your home. Maybe you put a new roof on. Maybe you did the kitchen. Maybe your landscaping is spectacular.
And finally, we look at what the market is doing in your neighborhood — the current market conditions, whether homes are sitting, whether there's inventory.
These are all things that really make up the actual value of your home. That's where a real estate professional can evaluate those key factors for you.
How a Zestimate differs from a CMA
| Factor | Zestimate | CMA |
|---|---|---|
| Data source | Nationwide algorithm using tax records and public listings | Live MLS data — five active, five pending, and five recently sold comps in your specific area |
| Home visit | None | A person familiar with your neighborhood evaluates condition, updates, and layout |
| Neighborhood context | Metro-average signals; can miss block-by-block variation | Street-level read on inventory, days on market, and buyer demand right now |
| Updates and condition | Not factored — the model doesn't know about your new roof or kitchen | Explicitly weighed against comparable sales and current market conditions |
| Accuracy for pricing a listing | Starting point at best; often off by 5–15% either direction on individual homes | The number the MLS, buyer agents, and appraisers actually respect |
Portland home valuation FAQ
How accurate is the Zestimate for a Portland home?
Zillow publishes their Zestimate accuracy data and consistently shows meaningful median error rates — noticeably higher for off-market homes than on-market ones. For a $700,000 Portland home, even a low-single-digit error rate translates to being off by tens of thousands of dollars. Zestimates are useful as a starting point, but not as a listing price or an offer basis. A local Comparative Market Analysis is what the MLS, buyer agents, and appraisers actually respect.
What is a Comparative Market Analysis (CMA), and how does it differ from an appraisal?
A CMA is a real estate professional's evaluation of what your home would sell for right now, based on 5 active, 5 pending, and 5 sold comparable properties in your immediate neighborhood, layered with a read of current market conditions. An appraisal is a licensed appraiser's formal opinion of value, typically ordered by a lender after a buyer's offer has been accepted. Both use comps, but a CMA is faster, free, and forward-looking; an appraisal is regulated and used to justify a loan amount at contract.
How often does my Portland home's value change?
Your home's market value can shift meaningfully month to month, especially in a market where interest rates, inventory, or buyer demand are moving. A single recent sale on your block can move the number. Homeowners who are actively considering a sale should request a fresh CMA rather than relying on one from six or twelve months ago. Owners who are not selling still benefit from an annual valuation for refinancing, estate planning, or long-term financial planning.
Can I get a home valuation without committing to sell?
Yes. Own It Northwest provides free, no-obligation home valuations. Many Portland-area owners request one every year or two just to know where their home stands. There is no expectation to list, and the CMA belongs to you to use however you want — for refinancing, insurance planning, or simply knowing your equity position.
What factors most affect my Portland home's value?
Three factors dominate: comparable sales on your specific block (what similar homes have actually sold for in the last few months), your home's specific condition and updates (roof, kitchen, HVAC, landscaping), and current market conditions in your neighborhood (inventory, days on market, and buyer demand). A citywide Portland average tells you very little about your specific home. The right answer comes from a person who knows your neighborhood evaluating your specific property against real recent comps.
