I assume the house she's moving from is the one her former boyfriend arranged for her to rent when last season started filming. Recall she was allowing all her doggies to pee on the floor of that house. She didn't seem to understand that you take the dogs out to do this. She said then she was renting. Even with her various jobs, I don't think she could afford to purchase real estate in those neighborhoods.
And Kyle was already well endowed, IMO. Odd decision, especially with her being a runner.
