Wish Me Luck on a Potential Deal

Hello All; Two months in and we may have something to put under contract. By way of word of mouth. So far things are sounding good. I thought I tanked when initially being introduced to the seller. I felt like I had what I'll call Newbie's tongue. But, we just got word today that the seller was impressed, that it helped that I spoke slowly. Since he is in his 80's and his hearing is not so good. I also followed up the introduction with a Thank you letter (like what job hunters should do after being interviewed). I asked for advise from other investors on the letter and received advise on adding a line that mentioned giving me a 20 day assignment of contract, in order to involve my associate cash buyers in the area. Which I do already have. He was also very impressed with the letter I sent. Now, to get through the nerves of anticipating the phone call and negotiating the purchase price.
