Help on my "out of town property owner

Hi everyone,
I mailed about 100 post cards. I got 4 calls but before I return the calls, I am seeking some advise on one of you than have done some deals.
I want to know now when I call to tell the owner that I am an investor? if I can't purchase the home should i be upfront on the first call about my intention either( lease option, owner financing, option contract). If they cant travel for showing, do I ask to send keys or to call tenants to show me the property? Afterward what kind of forms I am going to use to make the transaction happen?

Thanks for any advice
