Got first lead, need help with first contact

[Zlatan Omeragic]

Hello friends,

I have a lead on a possible investment property that I picked up from my neighbors. Its a actually the house that is next to my residence - estate inheritance, absentee owner etc...

My neighbors know the owner, who is an elderly lady, and they know the house as they cared for it for a couple years. They were able to tell me about the house a bit as well, and its sounding like it may be possible to make a deal on it.

They have provided me with a phone number where I can reach the owner. I really wanted my first contact to be a letter (just seems 'easier' for the first lead) but I did not want to pry too much for a strangers address. 

So I am hoping some of you could give me some tips before I call this lady that may help me increase my chances of getting her what she needs and making a deal that's worthwhile for me.
