Magliano is one of this wonderful areas Italy and in particular Tuscany is full of...in the middle of nowheres... amazing views all around, beautiful properties...and wine and olive trees. And all of this is practically the only base for an income, means tourism and some "agriculture". (And there are many areas as beautiful as this one but closer to some of the famous spots)
The wine and olive oil prodction is highly expensive in labor cost, you need to invest a lot of work in your prodcts.. so difficult to make them profitable . The quality might be excellent, but a bottle of olive oil for 20+ Eur struggles in competetion if you dont have a well-known brand.
Same for tourism...Lots of offers, lots of choices for travellers in all categories..Many families have this big properties and try to save them in opening for rentals...
If you drive around there you see all around signs for wine and oil out of own production and accomodation
You remember the vlog on another property of Gs family, which is abandoned for a couple of years? Which was a restaurant also? It was said this close to another wonderful area, Val d'Orcia. No wonder why and they now try to offer it for "fair price" even in Youtube ..... I have seen so many left places ...you live in postcard beauty, but it is a fight to survive...
Some old families there are rich in property, but cash is a challenge. It seems Gs family is a typical example. The mother manages the touristic rentals they do already, the sons have jobs in the city and are supporting on the weekend the family business'...
For K this is an endless source for vlogs...rennovation, decoration, views...And coincidently this is "publicity"...hoping to catch some of the viewers who want to live at least for a vacation the tuscan dream....
