We're about to complete on the sale of our property which we bought using help to buy 4 years ago but we (our solicitors) need to apply to Target HCA to get authority to complete once we have a completion date. Does anybody know how long it can take? Their website says 15 working days but we've been told it can be expedited. There's been other communication with them throughout the process which we've called and sorted ourselves in no time at all so I'm hoping this final step can be done just as easily.
