Kirstie and Phil help two sets of first-time buyers who have chosen to put down roots in south London. Phil is helping Niki and Rob, who have worked hard and saved hard for a deposit for their first home and, as a result, are searching with a generous budget of £450,000. They are looking for a home to suit them at the moment as young thirty-somethings, but that will also give them the space to have a family. Can Phil find a property which gives them the right balance? And Georgie and Louis love London - they work there, they go out there... the only thing is they don't live there. They've been together for five years and, during that time, they've been living with their respective parents in Surrey. Cue Kirstie to help this couple ditch the long commutes and find a place they can call their own. With their budget of £220,000, Georgie and Louis have missed out to faster buyers so, with speed the name of the game, Kirstie is in for a surprise as these first-time buyers strike in record-breaking time.
