I am selling my PPR. Initially purchasers were using ING who sent a valuer through the property last week. Valued at 440k (sale price). However at the last moment ING would not lend all the funds required so purchaser went to Bankwest. Bankwest valuer came through property yesterday. Find out today they valued at 420k. Therefore the sale is now in danger of falling through. Purchaser still wants to buy at 440k. What are their options. Yes they are using a broker.
