what is your opinion on first phone call?

[Account Closed]

i am about to send out 50 mailing letters to absentee owners.

some people say for the first phone call not to find out too much. they tell me to find out the property address and than to hang up find out comps and call back for more information.

some say to find out more. how much they want for the house, why they are selling, how much equity they have, how motivated they are, etc.

opinions? how much information should i have by the end of the first phone call?
