The problem

Generic skip-trace tools weren't built for HB 1110.

PropStream tells you who owns it. DealCheck does the math. Neither knows what you can actually build under WA's new middle-housing zoning. That gap is where deals get lost.

Filter spreadsheets, not parcels

Manually cross-referencing zone codes against lot dimensions to figure out what's actually buildable wastes a week per market.

Skip-trace dead-ends on LLCs

Consumer databases don't index legal entities. Every "investor-owned" parcel becomes a no-match — your highest-value leads.

Proforma math without zoning context

Standard calculators don't know fourplex setbacks, transit-bonus 6-unit rules, or city-specific coverage caps. Your numbers don't match the real envelope.

What you get

Three things no other tool combines.

Skip-trace + LLC unmasking + direct-mail fallback

Tracerfy phone/email lookup with BatchData fallback for the parcels Tracerfy misses. When the owner is an LLC, automatic WA Secretary of State search surfaces the governors and registered agent so you can trace the actual human. And when all else fails, the tax mailing address is one click from the parcel card.

  • Bulk CSV export ready for upload to your CRM

FAQ

The honest answers.

How is this different from PropStream or BatchLeads?

Both are nationwide skip-trace tools — useful, but generic. They don't know what HB 1110 changed about WA zoning. EastsideLots layers the HB 1110 envelope (setbacks, coverage caps, transit bonuses) on top of skip-trace + proforma so the parcels you spend a credit on are ones you can actually develop. Plus WA SoS LLC unmasking, which neither competitor offers.

What's the data coverage?

Parcel records for 7 cities across King and Snohomish counties: Seattle, Bellevue, Redmond, Kirkland, Issaquah, Sammamish, and Edmonds — sourced from county assessor and GIS records, with zone rules encoded per city. Skip-trace is pulled live on demand against the parcel's tax mailing record, so contact data is as fresh as the moment you run it. Coverage expands based on subscriber demand — tell us where you invest and we'll prioritize it.

How accurate is the proforma?

The HB 1110 envelope math is precise (LUC 20.20.538.C.1 for Bellevue, equivalent per-city tables for the other six). Construction costs default to a $350/sf 2026 PNW benchmark with trade-level breakdown you can edit per parcel. Sale prices use per-city retail $/sf medians; rental exit uses per-city cap-rate medians. Defaults are conservative for an unsophisticated build — adjust the cost inputs and you'll see the numbers update in real time.

Where does skip-trace data come from? Is it legal?

We use Tracerfy as the primary skip-trace provider and BatchData as a fallback. Both source from consumer credit headers (GLBA-compliant), public records, and proprietary aggregators. Real estate investing is a permissible use under FCRA / GLBA, but you cannot use the data for consumer-credit purposes (deciding who to lend to, employment screening, etc.). You're agreeing to those terms at signup.

Can I export data to my CRM?

Yes — every list view has a one-click CSV export (parcel + owner + skip-trace + entity-principal fields, 46 columns). The CSV imports directly into Tracerfy, BatchData, and any standard CRM. CSV export is included in every tier. A REST API is on the roadmap for the Team tier — tell us if that's what you need and we'll prioritize it.

What if I run out of skip-traces mid-month?

Upgrade your tier from the dashboard and the higher monthly cap applies immediately — no waiting for the next billing cycle. Per-credit overage packs are on the roadmap. Either way, no surprise bills: when you hit your cap, paid actions stop and tell you exactly why, instead of silently charging you more.

Cancel anytime?

Yes. Cancel from your account in 30 seconds (no email chain, no retention call) and your subscription stays active until the end of your current billing period. After that, your favorites and portfolios remain in your account so you can re-subscribe later without losing your work.
