A word of caution.
Whilst taking the allowance and buying something is a good use of the opportunities presented and has worked for many of us purely because we were lucky enough to get in at the beginning before prices took off, it was a risk but has paid off so far. The big uncertainty is the EK utilities allowance. There is nothing to say that the company can not or will not reduce it to match market conditions. This will leave you significantly out of pocket if you have taken on a mortgage based on the premise that EK will pay off your bond if you stay long enough.
My advice to any new joiner would be to take the company housing for at least a year, Sit tight and do your research once you have settled in. Even a year might not be enough to suss out exactly how things work here.
Good Luck
