No, I mean draw down the loan cheque before signing any contract- your solicitor can hold it for a few days while you then sign contracts and vendor too-unconditionally. The worst that can happen is that the vendors don't sign, you end up returning the loan cheque to the bank and you lose out on a few days interest. This would mean a tight closing- ie I would envisage closing within a few days of drawing down the loan cheque. But this way the vendor gets unconditional contracts. This would all have to be agreed in advance and arrangements put in place.
