When placing an offer you might be asked to pay a small holding deposit – e.g £500 or £1000- to show you are serious. This will be refunded if the sale falls through, through no fault of your own. Consider whether or not to get Home Buyer’s Protection Insurance.
On the day of completion, the money & deeds of the property are transferred between each party via the conveyancer. Legally, the seller has until completion to vacate the premises, and then you should be able to collect your keys – normally from your agent. After this, you’re free to remodel, renovate, move in or do with as you see fit. Remember: you may have to make arrangements for parking and utilities.
