Congratulations MaryMary62, how marvellous you will be near your family, that is priceless. Whatever extra you have paid will be forgotten when they are all in your garden
My top advice would be to wait until the chain is complete before instructing a surveyor. I would also recommend paying for an electrical check.
I would definitely have a second viewing near to exchange to closely inspect everything, check the shower, flush the toilet, look at the boiler, ask what if any appliances the seller is leaving, etc. I melted the bottom of the kitchen cupboard here with the toaster - or was it the kettle? Looked like wood during my quick viewing!
I didn't have an electrical check or a second viewing, and wish I had. I didn't want to ask the seller to allow an electrician in as she was very Covid nervous during my viewing, and from what I saw, the electrics seemed acceptable. I've just spent a whopping £400 to have 17 spotlight fittings changed to accept LED bulbs, as well as a new heat detector/smoke alarm.
Good luck, enjoy your decluttering and blessing people with the things you can't take with you.
