I found it odd that when she talked about the new place she kept speaking in 1st person singular. But now reading your comments, it all makes sense. She is definitely renting. That's why it's her "own decision" - if they had bought a house, it wouldn't be her own decision - since it would be Kenny who'd pay for it. I don't think she has enough money herself to buy a house. And yes as you guys pointed out she didn't mention "buying" even once. Why can't she be honest and say it explicitly?
That must be the reason she rushed back from Thailand, to sign the papers for the Cotswolds rental.
The thought that eventually you will want to end up where you grew up and that she always knew it would be like this is nice unless you have a partner with an international career.
