Data Contact Validation:
Start with the existing records displaying the Address of the Apartment building in the United States.
The assumed entity that owns it may be available, as well as the assumed email address and phone number (or maybe those assumptions will not be provided).
Need to find out what entity or individual owns the project and or what individual is the owner of the entity that owns the project, what their email and phone numbers are, as well as validate that the assumed email and phone number or your belief of the person, email, and phone is correct.
Looking up information via the Secretary of State and other software and search engines will be part of the job. As well as designing and implementing a way to validate via email or phone, or other ways.
