I have to agree with Rustyme, its about what you are prepared to put into it. To dive straight in at the deep end, without any employment to cushion outgoings is risky, but your choice. If you have skills to offer or trade, they could be helpful as you might get help in return, without having to stump up cash. Also don't forget animals, veg etc take time to grow and mature, so what do you live off while they do?
But, if it's what you really want and you don't mind being cold (and i mean Cold) early mornings getting wet and muddy (no turning over and ringing in sick), long hours when your exhausted, putting your hand in your pocket and getting no return for months. Stress free it ain't! And watching your chickens run free and lay eggs, seeing your pigs grow heavy and farrow, picking your own fruit straight from the tree, seeing your visitors enjoy your life style, fresh produce and eggs,feeding your chickens and pig. Then go for it, enjoy it and make the most of it.
