Rental income and running costs?
It is important to have a rough idea of what the running costs for your chalet or apartment will be. If you are purchasing in an apartment building of a development of chalets then the costs of maintaining the communal areas (garden etc) wold usually be divided proportionately between the owners, according to the size of their property.
As a rough guide the basic running costs for a property are usually calculated on a price per m2 basis, and this usually works out at around 3-5 euros per m2/month. This would cover the cost of snow clearance, rubbish removal, water rates, building insurance, local property taxes, cleaning and lighting for any communal areas, and maintenance of the gardens etc.
These figures would not include your own personal usage of heating and electricity as this varies depending on how much you use the property.
If you buy a property with extensive leisure facilities such as swimming pools and spas then these costs could increase to around 7-11 euros per m2/month.
