What is the ratio for Londonderry?

The 2017 ratio for Londonderry is 89.6%. This is set by the Department of Revenue (DRA). At the end of each year the Londonderry Assessing Department sends a report to the DRA of all arms-length sales data that occurred between October 1st and September 30th. The DRA compares the assessed value and the selling price to determine a ratio between the two. All sales between family members, sales within corporations, foreclosures, and fiduciary sales are not considered to be an arms-length sale and are eliminated from the data. The DRA calculates an average and determines what each Town's ratio is for the previous year. The 2018 ratio will be available in the spring of 2019.
