Yes they even had up to 125%(!) LTV iirc. But NR was just an example, the principle is the same, with 95% LTV you can be in negative equity pretty quickly especially if the mortgage is over a long term and doesn't have a low rate. When I was growing up you were told to expect minimum 10% deposit, although of course interest rates were higher then to.
The thought of being on a 95 or worse ltv is unnerving.
To be honest, I think it just kicks the can yet further down the road.
