Is it waterside? Is there good fishing? Does it have services (Electricity, water, sewerage, possibly phone)?
If so, it could make some money as a holiday unit to fishermen. That would at least bring some income- and contribute substantially to holding costs.
Without that, it's speculation- just a big gamble.
It could pay off (as it did for my grandfather, who retired quite comfortably). But it could bomb.
I'm not so much of a gambler (now). It's not something I would do.
But, if it does work out OK, and you don't go in for it, you may miss out on a great big fat bonus.
