Evaluate more properties in less time. A single RegWatch search replaces 2-4 hours of manual research across DOB, HPD, ACRIS, DOF, and DCP. Run preliminary due diligence on every property in a deal pipeline — identify issues before spending on inspections or legal review.
At $5 per report, screen 10 properties for $50. Find the deals worth pursuing and pass on the rest — with data, not guesswork. Pull violation histories, tax abatement timelines, and ownership records in seconds instead of navigating five separate government portals. For investors evaluating multiple properties per week, this time savings compounds into a significant competitive advantage — you see more deals and respond to opportunities faster than competitors doing manual research.
Understand the true carrying costs before you bid. RegWatch shows assessed value, tax class, current tax bill, exemptions, and abatement expiration dates. A property with a J-51 abatement expiring next year could see taxes triple — that changes your cap rate calculation entirely. Similarly, 421-a abatements on new construction have specific expiration schedules that progressively increase the tax burden over time.
Check for outstanding DOF balances, water/sewer charges, and ECB fines that would become your responsibility on closing. These hidden liabilities can total tens of thousands of dollars and are not always disclosed by sellers. RegWatch surfaces DOF tax lien sale risk, showing which properties are on or near the annual lien sale list — a critical signal for distressed property investors looking for acquisition opportunities.
Open violations, unpermitted work, lien sale risk, and compliance issues all directly affect investment returns. A Class 1 DOB violation (immediately hazardous) can trigger a vacate order, while accumulated HPD violations indicate deferred maintenance that will require capital expenditure. RegWatch aggregates risk signals from across city agencies and presents them in a clear, actionable format — color-coded by severity with estimated remediation timelines.
The AI analyst can generate investment summaries highlighting key risks and opportunities — useful for internal memos, investor presentations, and loan applications. Cross-reference violation data with permit history to identify buildings where unpermitted work has been done, a common issue that affects insurance coverage and resale value.
RegWatch streamlines the investment due diligence process into a structured workflow. Start by searching any NYC, NJ, or CT address to pull the complete property profile. Review the violation history across DOB, HPD, and ECB to assess compliance risk. Check the tax record for abatements, exemptions, and outstanding balances. Run the title and lien check to identify encumbrances that could complicate acquisition financing.
For each property, RegWatch generates a comprehensive report you can share with partners, attorneys, and lenders. The report covers 12 categories: ownership, violations, permits, tax analysis, title history, zoning, environmental, comps, risk scoring, and more. Use it as your standard diligence package — consistent, thorough, and backed by data from 270+ government sources.
Violations are negotiation leverage. A property with 15 open DOB violations and $40,000 in unpaid ECB fines has quantifiable remediation costs that should be reflected in your offer price. RegWatch breaks down violations by agency, severity, and status so you can estimate the true cost of bringing a building into compliance.
Distinguish between cosmetic violations (peeling paint, missing signage) and structural issues (illegal conversions, fire safety deficiencies) that require significant capital. Track the violation timeline to understand whether issues are recent or long-standing — a pattern of recurring violations indicates systemic management problems, while a single recent violation may be a minor issue easily resolved.
Once you acquire a property, RegWatch continues working for you. Active property monitoring checks five data sources daily — violations, permits, DOB complaints, tax lien sale listings, and certificates of occupancy — and sends you email alerts when anything changes. Catch new violations the day they are filed, not weeks later when a tenant complains or a lender asks questions.
For multi-property portfolios, monitoring keeps you ahead of compliance issues across your entire holdings. Full Analysis ($15) reports include 180 days of monitoring on the purchased property; Pro and Unlimited subscribers get perpetual monitoring across every property in their portfolio.
RegWatch focuses on regulatory and compliance data from 270+ NYC agencies — violations, permits, tax, title, zoning, and environmental records. PropertyShark is oriented toward market data and comps. StreetEasy focuses on listing data and rental prices. RegWatch is the due diligence layer that complements market analysis — it tells you what problems a property has, not just what it sold for.

RegWatch title abstracts cover 12 categories: ownership, deed history, mortgages, liens, judgments, violations, permits, tax status, zoning, environmental, risk scoring, and compliance. Generated instantly from $5 per report.
Search the property on RegWatch to see all open and historical violations from DOB, HPD, and ECB. Focus on Class 1 (immediately hazardous) and Class 2 (major) violations, which may require significant remediation costs. Check for unpaid ECB fines that could become judgment liens. Use violation counts and severity as negotiation leverage to justify a lower offer price.
Key NYC tax abatements to monitor include J-51 (renovation incentive, common in older multi-family), 421-a (new construction, phased expiration), ICAP (commercial/industrial), and Article 11 (affordable housing). When an abatement expires, the tax bill can increase 2-5x. RegWatch shows current abatement status and expiration dates so you can model the true long-term carrying costs.
Reonomy focuses on commercial property data, owner contact information, and market analytics. RegWatch focuses on regulatory compliance — violations, permits, tax liens, and government records. For investment due diligence, RegWatch provides the compliance and risk layer while Reonomy provides the commercial market layer. Many investors use both tools at different stages of their process.
