$500k kallaroo = no chance or a dump that you will then have to spend big on.
More chance of something in beldon or padbury although could be small and/or dated also. Maybe look at craigie as well ?
Buyers market at the moment but imo that will change in next 12 months.
More deposit the better, banks have also tightened up here.
We moved with an 11 and 7 year old and decided that we wanted the children to start the whole school year - so arrived in January for a Feb start. This was 11 years ago and at that stage year 7 was the last year of Primary school so that was important for our 11 year old to get a whole year in before another change.
Have a look on myschool - which gives you some indication of schools but to be honest like any school in the UK the feel of the school is probably one of your best indicators - not all children are academic and you want to achieve an all round balance.
