We’re surviving on SS alone. However, our “investments” included going debt free. It means our cost of living, even with 32 acres, is roughly 1/4 of our SS benefits. But we keep it low by splitting a cow with a neighbor and having a local butcher cut it up for us, growing a garden, fruit trees, raising chickens, etc. There is also a lot of edible wild “produce” in our area. We have so much wild garlic in our 7 acre lawn that in the spring and fall it smells like I’m mowing a salad. Fortunately it’s dormant during the summer.
I always wanted something like that but with a big stream I could partially damn to do my own hydroelectric.
