Most Massachusetts agents already know Zillow Premier Agent isn't great. The question is: what's actually better — and why? I spent 12 years as a licensed agent in Massachusetts. I paid for shared leads. I watched deals go nowhere. I built CORVENIS because the answer was already sitting in courthouse filings that cross every registry desk in this state, every single day.
The Product
Zillow Premier Agent gives you a share of voice on Zillow listings in ZIP codes you pay to advertise in. When a buyer clicks "Contact Agent" on a Zillow listing in your ZIP, Zillow shows them a panel of agents — one of which might be you. That's not a lead. That's a lottery ticket.
The more agents who buy into the same ZIP, the smaller your share of that panel. You're paying for visibility, not exclusivity. The product has a 2.2 out of 5 star rating on G2, with agent reviews citing "garbage leads" and multi-year contracts with no closed business to show for it. One case that circulated widely across BiggerPockets forums: an agent spent over $36,000 with Zillow and reported zero deals as a result.
The Cost
The number Zillow gives you in a sales call is not the number you'll pay. Here's the math Massachusetts agents actually report:
Run that math. At a 2% conversion rate, you close 2 deals per 100 leads. If each lead costs $40, that's $4,000 to close one deal — before your time, follow-up costs, or the CRM you need to manage the pipeline.
The Catch
When a buyer contacts you through Zillow Premier Agent, that buyer is also being shown to other agents. The lead is shared — by design, not accident. So you pay $40 for a name and a phone number. You call. Another agent already called. A third agent is about to call. The buyer is annoyed and ignores your voicemail. You're not buying a lead. You're buying a slot in a race you didn't know you were entering.
Head-To-Head
| Zillow Premier Agent | CORVENIS | |
|---|---|---|
| What you're buying | A shared slot in front of a buyer who clicked a listing | Direct intelligence on a homeowner already in a life-event transition |
| Exclusivity | Shared by default; multiple agents per lead | Territory-exclusive at Premier and Broker Office |
| Typical cost | $2,500–$3,500/mo for meaningful ZIP coverage | $49–$199/mo flat, by plan |
| Lead-to-close rate | 1–3% (industry-reported) | Not yet published — CORVENIS is in pilot, no closed-deal data to cite yet |
| Data timing | Real-time buyer clicks, low intent | Next-day after public filing, high intent |
| Contract | Often multi-year | No contracts, cancel anytime |
CORVENIS is in pilot — no closed-deal conversion data exists yet to compare against Zillow's published rate. We'll update this row with real numbers once we have paying customers to report on.
The Alternative
A motivated seller lead from public records isn't someone who browsed Zillow and clicked a button. It's a homeowner whose name just appeared in a court or registry filing — a probate action, a divorce filing, a notice of default, a tax lien. These are people in the middle of a life event. The property decision isn't optional for most of them.
CORVENIS tracks five live signal categories from Massachusetts Registry of Deeds and MA Courts filings:
Together, these represent a combined 30,000–34,000+ potential seller signal events annually in Massachusetts. The question isn't whether these leads exist. They do. The question is whether you're seeing them.
Why It Matters
A Zillow lead is a buyer who typed an address into a search bar. Maybe they're serious. Maybe they're just curious. You're paying for the chance to find out. A public records lead is a homeowner whose situation changed — their spouse filed for divorce, their mother's estate went into probate, they got a default notice. The intent isn't in question. The timing isn't ambiguous. The filing happened. It's on record.
Most public records data platforms pull their data monthly or quarterly. CORVENIS ingests Massachusetts filings daily and delivers next-day after filing. That gap — hours instead of months — is the difference between being the first agent to reach a motivated seller and being the fifth, after they've already interviewed three others.
