Price Euro 330'000. Adtl. investments Euro 2.000.000.-. Annual runnig costs and maintenance: high. Local taxes: high.
Revenue: unclear and uncertain. Provided local politicians can convince local banks to finance a project: why not:
Apart from the Euros 330,000 I am not sure that any of the above is correct; but it depends on how you want to live your life and what you would want to do with the place
Local taxes will be very reasonable and will vary on usage - development costs will vary depending on what is done and who does it - but 2 million Euros is way, way too much to spend unless you are insane.
The income potential even with a reasonable investment, say, less than Euros 500,000 would be good and far, far better than what Euros 1 million gets you in bank interest or similar, (maybe Euros 30,000 gross), these days - – and you will have the joy of the “life style”
For me it is too far North, I would not want to live "up there" and from the images, I find the site and buildings unattractive
We prefer the South or South West, (or the Pyrenees - which we have yet to explore) – more interesting countryside, variation, weather, etc., etc.
We live in a similar, maybe smaller, sized "hamlet" but more South, inland from Bordeaux - weather much better etc., etc.
Here is an image - sorry it's not good - It was taken about 20 years ago ........ we have almost half of the buildings - that's our pool on the hill - we were in the process of building it, when the shot was taken - I can see the rubble by the pool and in front of the house.
About 35/40 years ago it, (the working "farm"), was left when the owner died, (he dropped dead in a ditch when he was out jogging!), as all his children had moved to “The City”. French succession laws then caused the buildings to be sold off and now there are 5 houses. We bought our “bit” in 1988 and since then have spent quite a lot of time working on the house(s) and dépendances, (barns etc.,). Since I retired two years ago the effort has increased. It is a lovely place to live and we really enjoy it, but it is not for all - we have only ever used ours as a "place to live"
