We did it by waiting until our children were independent, selling the family home ( well, tbh we are currently on a hefty 2nd mortgage to buy this smallholding until our family home sells god knows when
) and both of us continuing with our f-t employment even though my husband is now 67. Theres currently no plan for him to retire from the day job because, to be frank, we cant afford it.
We also do everything on our 9 acres ourselves, which has resulted in quite a bit of unexpected expense in plant and equipment, and we were not complete novices in land management. But its different when the condition of the land is 100% your responsibility. Its only you who will do all the jobs and remember to schedule all those jobs. And , WOW, are there one hell of a lot of jobs!
