Hi Biggerpockets,

There are three questions I need help answering:

1.  Where am I able to access the national database of all property records for free (e.g. address, homeowner, zipcode, etc)?  I understand that the county clerk have these records, BUT am I able to subscribe or access their database? How would you address this question if you are trying to build a national database? 

2. Is there a national database that I may subscribe or pay a small fee to access all the property records in the United States?

3. Also, there are websites that offer inherited trust records or probate cases;  how do these companies access these records in all counties and be continuously updated with new cases/inheritance?  Do programmers create a script to scrub the data, but then where do they get the data?

All inquiries and tips are appreciated.
