Has anyone else encounted a large amount of errors in a screening?  We got both Wealth Point & Prospect Point and screened over 100K donors from an initial 1.3M database.

We are still working with the results three years later, but now that we are getting down to doing in-depth research of prospects, I've find a lot of errors in real estate vaulations.  This is BIG because Blackbaud bases the model scoring heavily on real estate.  (We first reported these errors in 2006 and BB told us they couldn't do anything about them).  The issue has been re-opened because we want to do another screening, but Blackbaud will not be a candidate unless they can explain why the errors occurred and what they would do to prevent them in the future.

All I get is noise about the errors being passed along by another vendor to BB, but I say if they want to instill confidence, they would correct them.  Originally they tried to blame the errors on individual county assessors, but then when I pointed out (with the help of my IT background) that different assessors all over the country couldn't have made the same mistake at the same time, then they blamed Lexis/Nexis.  It doesn't stop, and I don't care.  BB sold me the data screening, not L/N, they should make it right.

Has anyone else spotted the same sort of errors, or (horrors!) othe sorts of data errors?

I know your post is several months old, but I wanted to pass along that my organization has done three Wealth Point screenings in the last year on select groups of constituents from our database. We've only screened around 50,000 records of our 200,000+ donors for now. I work with the data on a daily basis and have noticed several errors in the real estate listings. One of the biggest problems has been Wealth Point pulling up the same property listing multiple times for a prospect. This inflates the value of the prospect and can produce deceiving results when I'm running a quick report and not checking each prospect individually.

I've also noticed incorrect real estate values for propsects that are clearly the result of human error. For example, Wealth Point lists a prospect's home value at $26 million, but a closer evaluation reveals that the home is actually only worth $260,000. My guess is that the decimal point was simply omitted, but there's quite a difference between $260,000 and $26 million!

Occasionally I've found a Dun and Bradstreet listing or a Foundation Connection that isn't correct, but the match code usually indicates how likely the match is. It's very rare that I will find an A1 match that isn't correct.

While it can be time consuming to examine a prospect's 30 real estate listings and delete the duplicates to reflect the prospect's true assets, Wealth Point has still saved me countless hours of individual research on potential prospects. Before passing along a list of good prospects or having someone approach a prospect that was revealed through Wealth Point data, I always double check to confirm that the information is accurate.

Hope this helps!
