Whats my next move presenting an offer to out of sate seller?

[Doug Haisten]

An out of state estate executor (IL) contacted me if I was interested in buying a house local to me (south AL). He has only seen the house once years ago and had no idea for a sell price. The unmaintained and vacant/abandoned house needs a good deal of work. I sent him pictures of the house and the areas that needed work. Since out initial discussion he does not answer my calls but does respond to texts. Its been 3 weeks since the original discussion. I texted again if they were interested in selling the house. His texted reply was "yes, what's my offer?" I have not discussed a price for the house or the repairs and did not answer his question of what my offer is. I also learned he is not the executor but his wife is the executor and I have had no discussion, voice or text. What's my next move and what's the best way to "deliver" or present an offer to an out of town seller?
