Real Estate Transfer Data

Under state law, a Real Estate Transfer Return (RETR) must be electronically filed (e-filed) with the County Register of Deeds when recording a conveyance of real estate.

RETR Data

RETR information may be used to determine a property's market value. The best indicator of market value is a transfer representing an arm's-length transaction.

Characteristics of an arm's-length sale:

  • Property must have been on the open market for a period of time typical of the turnover time for that property type
  • Both buyer and seller must be knowledgeable about the real estate market and the uses (present and potential) of the property
  • Must be a willing buyer and a willing seller, with neither compelled to act
  • Payment for the property must be in cash, or typical of normal financing and payment arrangements for the property type

Not all Real Estate Transfer Returns represents arm's-length sales:

  • Examples include: family sales, correction deeds and delinquent tax sales generally are not considered arm's-length transactions. However, with these transactions, you must still file a RETR.
  • Note: The Wisconsin Department of Revenue (DOR) is not responsible for the accuracy of the data contained on the RETR, and will not aid in its application or analysis
