I think temporary housing is a good bet- in some cases it won't take very long at all to rent a house once you're over here. We have just signed a lease for a new house and the timeline went like this- found a house that looked interesting, went for a viewing 2 days later, looked at some more houses that week, decided we wanted the first house, sent over the references 2 days after that, and then the landlord mailed us the lease the next day.
Basically, going from looking at houses on the internet to signing a lease was done and dusted in about 9 days- I couldn't believe how fast it went! This was with a private landlord though, going through an agency will probably take longer.
