ATALI ELECTRIC vs Reonomy
ATALI ELECTRIC vs Reonomy for property tax work
Reonomy answers who owns a commercial property, what they paid, how it is financed and how to reach them, which makes it a strong prospecting tool for tax consultants looking for new clients. ATALI ELECTRIC starts where that research stops: once you have the engagement, it builds the income, sales and uniformity evidence and the county filing. Many firms will reasonably use both.
What it is
Reonomy is a commercial property data platform that has operated as an Altus Group business since Altus acquired it in November 2021. Users search and filter commercial properties by asset class, geography, sale history and debt; see the people and entities behind LLC owners and their portfolios; pull owner contact details, sales, mortgage and lien history and assessor-sourced records; and use a likelihood-to-sell score to time outreach. Data is available in the web app, as exports, through an API and as bulk data feeds. Altus Group separately sold its property tax consulting business to Ryan, LLC in a transaction that closed in January 2025, so Reonomy sits within Altus's analytics business rather than an appeal practice.
