I'll help with one of your questions - we offer both Toll-Free and Local Number options.

As Michaela suggested, Ancestry gives me quick access to U.S. and my home state's Social Security a Death Index.Accurint.com is probably the best of the best when it comes to data providers but expensive, with a $250/month minimum fee.

Could be a death, divorce, bad tenant or any number of things that will finally cause the owner to make a decision to finally sell the home.  

If you truly do 5-10 deals per month, you will be working your self to death.

I have been involved with direct mail for over 20 years albeit in a different part of REI.My experience is a toll free number (800, 877 etc prefix) makes your operation appear more professional and large scale.

You can do the same with a vanity toll free number.

The Co-owners have discussed the co-ownership of the Property and have concluded that to avoid conveyance and ownership problems created by death, bankruptcy or insolvency, disputes and the like, it is in the best interest of each Co-owner that the holding of the Property be governed by an agreement which defines the rights and obligations of each Co-owner in the form of this Agreement and in compliance with IRS Revenue Procedure 2002-22.II.

Example Probate = mostly family a death issuesTax = mostly income issues ect...You will be most successful working in areas you are comfortable speaking with people about and then grow as a person from there into other areas. 

They are also scared to death to act, again, lack of education.

Later I can expand into a website, toll free number and automate, in order to eliminate the tire kickers.Thank you, all
