Speaking from experience, there are a lot of "data" providers out there, but the majority of them are bottom feeders that scrape/purchase information once it reaches a certain age (30/60/90 days usually)
My career is in the information sector (risk management) and 6 years ago when I began I had NO CLUE how valuable information is. I started basically as an "information broker" but quickly found and developed my own niche.
I've learned a lot about data providers as they relate to my field and the various sectors related to it. I only work with 2 different providers and have the ability to pull both public/non public records including Experian, Transunion & Equifax. I can also pull detailed personal, criminal, financial & financial scoring information in real time. The only reason I say this is because I have seen how "critical data" has evolved in the short 6 years of my career.
I am willing to share some sources with you, you will have to contact them and inquire more specifically with what you want, but I assure you they are as close to the top as you'll find. I don't know that they are the perfect solution for what your wanting, but they will certainly help or point you the right direction. I also have several firms I work with that specialize in distressed real estate/real estate workouts etc. so I can inquire with them as well. I will PM you with more specific info, and hope you find what your looking for.
One provider that I can list publicly is Ebureau.
They provide mass data to major providers & institutions. If I can find the number to a decision maker I know there I will forward it to you. You can also inquire directly.
