Assessed at a fraction, capped on the way up
New York assesses most property at a fraction of market value and limits how fast the assessed figure may rise year to year. Both rules push the number on the roll away from what the building would fetch, and neither is a discount a buyer receives. Reading the assessment as a valuation is the commonest mistake made with this data.
What the roll does give you
- The land value and the total, so the improvement is the difference.
- The year built, and separately the year of the most recent alteration on record.
- The unit count, split residential and total.
- Floor area, and separately the commercial, residential, office and retail parts of it.
- The zoning district, any overlay, and the historic district or landmark status.
That is more than any other city in this product publishes on its roll. Cincinnati's county, by comparison, gives a market value and almost nothing else, and its report has to name the year built and the unit count as absent.
What it does not give you
A sale price. New York records transfers through ACRIS, a different system on a different schedule, and it is not in this feed. A report that showed no sale would be saying nothing about whether the building sold, so it says nothing rather than implying it never did.
