For many years we've explored ways to link the record for a particular property on the local assessor's website to the corresponding deed on the registry of deeds website. For a variety of reasons, it has been a difficult connection to make. The city of Lowell, however, recently inserted a button on its website that allows users to go directly to the searchable Middlesex North section of MassLandRecords.com.
If you go to the city of Lowell assessor's site (http://www.lowellma.gov/mis/Pages/General/GIS.aspx
and click on the blue "Access Property Info" box. That will display the search field where you can retrieve a parcel map and property info by address, street name or by owner name. Once you've retrieved the parcel info, a map will display in the center of your screen and data about the parcel will appear in a smaller window to the right. Towards the bottom of that data is a line that gives the registry book and page number of the deed into the assessed owner. Below that it says "Access Deed Info". Clicking that (now) brings you to the MassLandRecords site, ready to search. In the not too distant future, we hope to use the book and page link shown on the assessor's record as a link to the corresponding document on our website. Hopefully we'll be able to reverse the process as well so that viewing the deed on the registry website will offer a button that says "View Assessor Info" that will take you right to the corresponding page on the assessor website.
