Hi A&A
Yes very do"able"
You may be a little insane but let people that arnt insane throw the rocks from their cosy little homes on land that dream about doing what you will do, (not directed at you uncleBob

)
Im assuming you going to put tenants into your house so that will be repaying the mortgage on top of the payment you will make as you will still be working.
So it makes seems to me to live a life you want, money/wealth is measured by happiness not bank balance.
( I have plans in place to do similar in a few months, even have my redraw from bank approved)
