hey victor, if he is getting a bank loan, the bank will ask him details of the seller and can transfer the money into your account straight away.....my suggestion would be like not to involve with cheques....i have done payment to the seller when i got the car, the loan money acts like this....
once it is approved, the bank transfers money into his account, if he provides your bank details, the bank will transfer the money from his account to yours and it will reflect into your account in 15mins....i have done this before.....since he is interstate buyer, i would recommend this option....
