You can prevent a sale cancellation if you prepare early and seek good advice. First, instruct a conveyancer as soon as you agree to sell or buy. Next, always check your finances and secure a mortgage in principle as early as possible. If you plan to sell, respond quickly to legal queries and prepare all documents before delays occur. Meanwhile, buyers should arrange property surveys right away to spot any issues early. Both parties benefit when they maintain open communication and show flexibility throughout the process. Additionally, you can use reservation agreements to provide extra security for everyone involved.
