So we’re part or a chain and was under the impression all was going well and we were close to exchange. It turns out our buyers do not have their mortgage offer. The valuation was done months ago and we were told that they had their offer by our estate agent. Searches done and queries answered so everything else in check. Anyhow they are now not able to get the LTV they need and need to increase their deposit by 5%. If they are not able to do this what options do we have? Thanks
