A BIT MORE
1. The buyer is the one who should have made the condition not the seller and since the seller made the condition instead it is not a valid condition.
2. Since the seller will buy it back as soon as he has the money it is a loan not a sale and the buyer is eating the fruit of the field in the interim as a reward for the right of the seller to hold on to the money in the interim and it is Ribis.
3. Since the seller should have made the condition not the buyer it is not a valid condition and it is as if the buyer said if I want I will sell it back it to you therefore since seller can't force him in Beis Din to give it back it is a sale not a loan and if he does give it back he is reselling it and it is not Ribis.
4. She was not accepting a condition she was just trying to comfort him.
5. It is an Asmachta because the borrower is promising to give a field that is worth more than the loan in the event that he doesn't pay back the loan.
6. Because he is only saying it out of embarrassment even though it is it yet time to pay back the loan he doesn't want that the lender shall have to go through the trouble of claiming the loan when it is due.
7. If he is drinking beer it is obvious that he is not even attempting to pay back the loan and he doesn't care if the lender takes the field.
8. Even though he may not collect the entire field if the loan is not repaid because an Asmachta is not Koneh, however the field is an Aputiki and he may collect a piece of the field that is equal to the amount of the loan.
9. According to one opinion that buyer may only collect from Beinonis because the remaining Idiyos is in place of the Idi Idiyos.
10. R. Huna holds like the opinion that a person may be Makneh something that has not yet come into existence however even according to that opinion he may retract if it is not yet in existence, while R. Nachman holds like the opinion a person may not be Makneh something that has not yet come into existence.
11. Because the seller was Mochel and even though he was Mochel b'Ta'us because he didn't know he had the right to retract even so it is a valid Mechilah.
