1) I too hav a loan with monthly 15K as deduction from my main salary account. My agent said its best to show as FD as that will not need elaborated bank statement. I had to show only the transaction where my parent's money had come in my account.. abt 1 week b4 making FD. My EMI date was after i made FD, so did not reflect in loan account. I would advice u to somehow trasfer that 1K or 2k to ur dad and ask him to send all 10K or required money as FD.
U will need only 1 week statement and FD acc statement and another balance statement from bank. I showed only 1 week statement of Dad to be safe. FD with gift deed is less complicated.
2) My parents had joint acount. Both names shud reflect. U can email me
