200,000 NEW Movers Added Weekly

AtoZdatabases 200,000 NEW Movers Added Weekly are compiled from data sources including:

  • Register of deeds records
  • New phone connects

When someone purchases a new home, the transaction is recorded at the local county register of deeds' office. In the majority of states, these records are made available to the general public and are obtained and incorporated into the New Mover Database. New phone connect information is provided by local phone companies whenever a new phone number is connected. On average, records in the new mover file have been in their homes for 3 to 12 weeks when they are made available to customers with most being there for between 30 and 60 days.

Records in the new mover file have not been sourced using the USPS National Change of Address (NCOA) product. License agreements with the US Postal Service prohibit the use of NCOA in any way to create a new mover database.

50,000 NEW Homeowners Added Weekly

AtoZdatabases 50,000 NEW Homeowners Added Weekly are compiled from data sources including:

  • Register of deeds records

New Homeowner information is provided by county register of deeds offices in most of the 50 United States. As properties are bought and sold, the deed for the property, containing the purchaser's name, the sale price and sale date, has to be recorded by the county government. In most states, these records are considered public information and are made available to the general public. However, the state law in several states does not require the recorder's office to make sales related information available to the public, including the sales price and sales date of the property. As a result, the number of new homeowner records in these states may be low. In addition, each county reports their deed information on a different schedule. Some counties report every week, some counties report once a month and some counties report whenever it is most convenient for them. This can result in a wide range of purchase dates being made available each week and fluctuations in counts in each county from week to week.
