What is was developed to create a user-updated database of historical resources for the Real Estate Due Diligence Professional. The Real Estate Due Diligence information Wiki (DueWiki) can be easily modified by anyone so that the information is current and useful for all site visitors. Anticipated site visitors include professionals conducting Phase I Environmental Site Assessments (ESAs) and Property Condition Surveys (PCSs). Also expected are those providing support research such as title searches and government records reviews involving local and federal offices, aerial photographs, historical maps, and city directories.

Along with DueWiki, will be tailored to the needs of the ESA professional through the use of classified ads, forums, travel information, tech deals, and anything else of value. Visit the forums to share interesting site visit stories, get help with specific site issues, or just to discuss current events if you work at home like many of us and you don't have the chance to complain about things with in-office co-workers.

We're just getting started, so please bear with us as we work through any bugs or issues. New features will be implemented over the coming months. Please feel free to contact us with any suggestions, recommendations, or bugs that you find on the sites.

What is a Wiki?

A wiki is a website that allows the site visitors themselves to easily add, remove, and otherwise edit and change available content. It also allows for easy linking among any number of pages. This ease of interaction and operation makes a wiki an effective tool for mass collaborative authoring. The most popular wiki is Wikipedia, which is a collaborative encyclopedia maintained by users throughout the world.

What is DueWiki?

DueWiki is short for "Due Diligence Wiki." My wife came up with the name when we were tossing around suggestions and it just fit perfectly. After conducting hundreds of Phase I ESAs, I became frustrated with the time-consuming process of researching where to get aerials, building permits, Sanborn maps, etc. every time I was going to visit a new area. DueWiki allows anyone searching for such information to have it readily available with a few mouse clicks. This DueWiki Sample Page shows what information DueWiki hopes to eventually have available for every County and Municipality throughout the United States.

Thousands of people conduct ESAs, PCSs, title searches, and historical research throughout the United States in connection with Real Estate Due Diligence activities on a daily basis. DueWiki is designed to allow those researchers to create one amazingly useful location for professionals to consolidate all of their knowledge regarding these research resources. These visitors, including you, can easily add, remove, and otherwise edit and change available content. Ideally, regular visitors to specific regions will update those regions so that professionals who infrequently visit those areas will be able to most effectively use that expert information.

Check out the DueWiki Help page for information on creating and editing pages. With your help, and DueWiki will develop into resources that are essential for all of us to complete our work more quickly and with greater accuracy.

What is the best way to use the information available on DueWiki?

Once you have verified that the information available on DueWiki for a specific area is correct, you can easily print out the page for the municipality in which you are conducting your research by clicking on the "Printable version" link in the left column. All of the addresses and information for that municipality will be available to most easily use with a GPS unit if you have one available. Using a GPS, you can simply plot your directions as you go and decide where you want to go next. An excellent selection of GPS units are available at If you don't have a GPS, map your directions from office to office using Mapquest or a similar online service.
