Real Estate Transfer Data
The seller of real estate is required to file a Real Estate Transfer Return (eRETR) with the county Register of Deeds when recording deeds of property conveyances. State statutes require those returns to be filed electronically beginning July 1, 2009. Below is a link to the electronically filed Real Estate Transfer data as of July 1st 2009 and forward. The data will be updated on a weekly basis.
Real Estate Transfer Return information is often used to determine the market value of property. The best indicator of market value is those Transfers that represent arm's length transactions. The following list identifies the characteristics of an arm's length sale.
- The property must have been available on the open market for a period of time typical of the turnover time for that type of property.
- Both buyer and seller must be knowledgeable about the real estate market.
- Both buyer and seller must be knowledgeable about the uses, present and potential, of the property.
- There must be both 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 type of property.
Not all Real Estate Transfer Returns represent arm's-length transactions. Transactions such as family sales, correction deeds, and delinquent tax sales generally are not considered arm's-length transactions, but still require filing a Transfer Return. These records do not convey title, but are tax documents.
The Department of Revenue assumes no responsibility for the accuracy of the data contained on the Return, nor will it aid in its application or analysis.
The historical data is similar to what is provided at the above link. Historical data includes scanned paper-filed returns vs. electronic returns which may be incomplete due to the scanning process.
