1. Assessee can pay whatever rate he likes but its better if rate is nearby market rate of interest
2. If interest paid during the year is more than 10000 then TDS is to be deducted @ 10% (Sec. 194A)
3. As such there is no last date for deduction of TDS, but TDS is to be deducted when expense accrue or payment is made whichever is earlier (in your case at the time of making payment) and after deduction TDS is to be paid on 7th of month following month of deduction like if TDS is deducted in month of June last date of payment is 7th July.
