It would help if you explained what type of property (flat, house), how much you like it, how convenient it is for you, and whether it is leasehold or freehold. Watch for properties where you are trapped in leasehold - like flats over shops.
If you are a cash buyer, why on earth are you employing conveyancers? Get the Which guide on buying and selling - it is an extremely simple task to convey a property if you are a cash buyer. I have purchased 7 and sold 6 properties altogether over the last 50 years, and only once employed a solicitor and never a conveyancer ( and that was with a legally complicated situation).
If you are simply worried about the value of a place going down after you have purchased it, you have to remember that a fall in the value of your own home will make the next move up that bloody property ladder far more affordable for you. All the places on your next move up will have become proportionately cheaper. Falling house prices are a blessing for a first time buyer, not a curse.
