Big surprise that the advice on a Tractor Forum is...
To buy the tractor!
Lol.
I'll be the odd man out too, I guess. Since you don't live there, but will "someday" move back, I would hire the work done at the homestead ranch and get the kitchen remodeled. Then immediately sell the house with the remodeled kitchen. Then move into your RV that you relocate to the homestead ranch and build a house there to live permanently. Once you've moved there, (in the RV), buy a tractor. You can use it to aide in the new home construction, as well as further maintaining and pushing back the wild brush on site.
You will now be living on your homestead, in a new house, with a new kitchen, AND you will have a tractor.
Done and done.
