Don’t rely on the Building Society valuation. The Building Society only inspects the property to see if the valuation is justified before the loan (mortgage) is granted. This is not a full structural survey. Legally the Seller is not bound to give any guarantees as to the condition of the property, the Buyer purchases it as seen. We may recommend a structural survey or a House Buyers Report by a qualified Surveyor. If the surveyor finds work that needs doing, it may be possible to negotiate a lower price with the Seller in order to cover the cost.
