I guess I have part of the dream, but you are right, it is not easy.
I spent a lot of years working to pay a mortgage, but now that is done
It's a small house, but that's fine by me.
I have a garden, but rent an allotment.
I have 2 jobs that are about full-time between them, but are local, so my days of commuting a long way are thankfully done. 1 of these is our own business (me and OH).
OK maybe you could start a business with Sammy, even if it was low key and in your spare time for now. You can have a business vehicle, phones etc. You still have to pay for them, but they come off your profit, so you don't pay tax on that money. A good accountant costs a few hundred pounds a year, but saves you thousands and has advice on all this sort of stuff
Selling veg is really tough to make money from, but selling food made from your produce could be way more profitable. What about a farmers market stall selling stuff, even if you had to buy produce at first to make your wares.
What about making and selling stuff on line. Are you crafty or have skills others might pay to learn? Services you could provide?
Renting might suit you for now. It does mean you could up sticks and move elsewhere in the country if you got an opportunity.
Get your brain going and think of an angle. Even if you don't make your fortune, you will have taken a step towards not being just a wage slave
