The most effective way to search for Probate records

[Account Closed]

Hi Everyone, 

I recently got access to a website with probate records. However, the list does not provide LTV ratio, when the house was purchased or any information that could help me decide which people to target.

So far, I have filtered out all the people without wills. It gives me the death date, will date, addresses and attorneys. Any ideas on how to search or target people more effectively? 

Also, I like to send yellowletters, but I'm not how to approach or what wording should I use in the letters. Any ideas would be greatly appreciated.
