Getting Actual Data Out of Zillow for Vermont Properties

Zillow's Vermont coverage has gotten noticeably better over the past couple of years, but it still has blind spots that will bite you if you're not paying attention. The Zestimate algorithm treats Vermont properties differently than say, a tract home in Ohio, and understanding why matters if you want to use their data for anything beyond casual browsing. I spent last fall trying to pull comparative market analysis data on a cluster of small-town Vermont properties near the New Hampshire border. Zillow's automated valuation model was off by 18 to 23 percent on three separate listings, all of which were older farm properties with non-standard layouts. The system kept defaulting to comparable sales from towns forty minutes away because there simply weren't recent sales within a tight radius for those property types.

The core issue with Vermont is the market structure. Unlike states where suburban subdivisions drive the majority of transactions, Vermont relies heavily on individualized properties, seasonal homes, and multi-generational farms. Zillow's algorithm, which is trained on national MLS patterns, struggles with this distribution. It also struggles with the fact that Vermont properties frequently change zoning classifications or have parcel splits that don't appear on public records until months after they happen. To actually use Zillow meaningfully for Vermont real estate, you need to layer their data with local context and know where their numbers are likely to be wrong. The Zestimate alone is not actionable for decision making on Vermont properties unless you've verified the comparable sales it pulled from. Click through to the "Comps" tab on any listing and cross-reference those sold properties with the Grand List data from the town clerk's office. Vermont towns are required to maintain property assessments through the State Board of Taxes and Assessment, and those records are publicly searchable. They'll tell you whether Zillow's model is using stale or incorrect square footage, bedroom counts, or lot size information. One specific workflow I use involves pulling the Zillow listing data, then going directly to the town's municipal GIS portal. Most Vermont towns now have interactive parcel maps that show actual lot boundaries, building footprints, and recent parcel splits. I overlaid a Zillow listing's reported lot size against the GIS data for a property in Rutland County and found the listing had been using a subdivided portion of the lot rather than the full parcel. That explained a 14 percent Zestimate discrepancy. The fix was simple: I adjusted the comparable sales selection in my analysis to use full-parcel transactions instead of partial-lot ones, which brought my valuation range into alignment with what the actual market was reflecting at the time.

The rental data side of Zillow works a bit better for Vermont, but only in certain regions. You'll get reasonable rental estimates for Burlington, South Burlington, and Montpelier. Once you move past those corridors, especially into northern Vermont or the western mountains, the rental data becomes sparse and the Rent Zestimates degrade quickly. I've seen Rent Zestimates that were off by several hundred dollars a month for properties in areas with fewer than fifty active rentals in the database. The workaround there is to pull actual rental listings from local sources like the Vermont Times or town Facebook groups and use those as your ground truth, treating Zillow's rental estimate as a starting point at best. Another thing beginners miss is that Zillow's Vermont market trends data is aggregated at the county level rather than the town level for many rural counties. Orleans County, Caledonia County, and Windsor County will show you county-wide trends that smooth over dramatic differences between individual towns. A town like St. Johnsbury might be seeing a ten percent year-over-year price increase while a town twenty miles away in the same county is flat or declining. The county-level aggregation makes both of those disappear into an average that tells you nothing useful about either market. If you're doing investment analysis on Vermont properties, Zillow provides export options for their listing and historical data that can be pulled into spreadsheet software. The export function is buried under the "Export" link on search results pages and only works when you have at least twenty listings in your results set. It gives you CSV access to listing price, Zestimate, rent estimate, property type, square footage, lot size, year built, and last sold date. You can then merge that data with town-level Grand List information to build a more accurate valuation model than Zillow provides out of the box.

The biggest limitation you need to accept is that Zillow's Vermont data will always lag behind what a local agent with a direct MLS feed knows. The MLS feeds Zillow, but there's a delay that ranges from a few hours to sometimes several days depending on the local board's upload schedule. In a fast-moving market like we saw in the Champlain Valley during the spring of 2024, that delay meant Zillow was showing list prices that were already outdated by the time someone pulled the data. If you're making an offer based on Zillow numbers alone, you're working with information that may already be stale. For most people researching Vermont properties, the practical approach is to use Zillow as a discovery and initial screening tool, then verify every significant number against municipal records and current MLS data before making any decisions. The platform is useful, but it rewards careful users and punishes casual ones. That's basically how it works everywhere, and Vermont just makes the gaps more visible than most markets do.
