Comparing the Processes

Filing an AR1 form manually vs. using our automated tool.

Takes hours or days

1. Look up your property info
Navigate the Department of Assessment site to find your Section, Block, Lot, external measurements, and current tentative assessment.
2. Determine your market value
Try to guess the "Full Market Value" on your own by comparing limits on assessment increases (6% annually, 20% over 5 years).
3. Hunt for Comparable Sales (Part E)
Spend hours searching the ARC sales locator for recent open market sales of similar houses within the past 6-24 months.
4. Decipher the 2027-28 AR1 Form
Carefully fill out parts A, B, C, and F. A single mistake or omitted section means your application is immediately considered defective.
5. Mail or Drop Off
Sign the form and physically drop it off at the ARC office in Mineola, or mail it before the March 2, 2026 deadline.
