Danny? It's Keira. You're a star! Sounds perfect. Bill must earn a lot to put a (1)deposit/loan down on a house in Oldham Street! Tell him that i'd love to come round and see the room. Do you know how much he wants (2)for/per week? And i'd need to move (3)into/in by the end of next weekif that's ok.

Hi! Glad to be able to help, Keira. Sorry, i don't know what he's (4)costing/charging, but it won't be outside your (5)expenses/budget. And i imagine it includes electricity and gas, so you wouldn't have to worry about (6)payments/bills like that. Bill doesn't earn that much - he's a(n) (7)house/estate agent and i guess that's how he got the house cheap! Anyway, i'll email you the details and tell him what a wonderful (8)tenant/sitter you would be. Of course, as long as i can come to the (9)housewarming/housewelcoming party!
