No fixed abode?

[Biscuits]

This is problem with my wife´s VAF4 settlement form and what to put as our address.

Before coming to Brazil to get married we both gave up our address´s in the UK as they weren´t suitable and we wanted to save a months rent. We have made plans and paid a deposit to rent a flat in London but the problem is with the address´s sections of the application form; we don´t know what to put in them. The ´where you plan to live section` isn´t a problem but if we put our old address´s in the ´contact details`section that wouldn´t be strictly true because we no longer live there. Do we put our old address´s because those are our last address´s, or do we put ´no fixed abode`? Or do we put where we are staying (temporarily) Brazil?

I feel a bit idiotic asking and I´m sure that the answer is glearingly obvious to some, but we are really hung up on getting it totally right.
