About a year to 18 months of looking, then bought a building plot, then two years in rented house (I had a 3 year old and an 18 month old at the time) before anything happened. Then the plot was bare, so we had to take it slowly. Now 5 1/2 years on, we have dairy goats, sheep, rear weaners for meat, chickens for eggs (and spare boys for coq au vin), polytunnel and veg garden.
But OH still works full time in Edinburgh, 45 mile drive up the A68... I gave up my career as I was only working to pay the taxman and for childcare... and am now a much happier person!
I would recommend joining Woof and working on farms, during the holidays. Conservation groups (like BTCV) are also really good to get to learn skills like fencing, tree felling and planting and just to be active outside in all weathers - we did a lot of conservation work before we had children.
