I like how WealthEngine evaluates our prospects in a variety of useful ways: Real Estate Value, Estimated Income, Donations to non-profits, Estimated Net Worth, etc. This helps us quickly identify our top prospects. The data is pretty accurate, but like any research, you will want to do some of your own verification of the data. WealthEngine gives us a GREAT starting point in evaluating donors.
