From a quality of life point of view, Switzerland is really great. I live in the border of Zürich and this is the view I have on the city from my balcony :
Even if I live in a 400k Inhabitants city, I can hear the cowbells and chickens every morning
Public transportation is really fantastic and surprisingly not that expensive for Switzerland. (My subscription for unlimited access in the area 50 km wide constituted by cantons of Zürich, Zug and Schwyz costs me around 55 CHF per month (i.e 50EUR). On the other hand, buying single tickets instead of subscription is really expensive. (A single ticket is 4.40 CHF in Zürich, instead of 1.10 EUR in Paris for instance.
I also go biking a lot, even if the landscape is quite hilly : I ended up having much better legs
The cost of life in general is very high here compared to other european cities, but it is compensated by high salaries.
For instance :
-Housing : It is very difficult in the Zürich area to find housing at less then 750CHF/month per person, even in a shared flat. I considered sharing a flat at some time but realized that I would end up paying the same, so it was not worth it. To cut down housing costs further, the next step would be to live in a RV or similar arrangement.
-Food : If you go to discount stores (ex:Lidl), you can expect to pay around 250 CHF per month per person for food. You could go down to 150 CHF if you don't eat meat (In the household our diet consist of vegetables and meat). However, if you go to regular stores (Migros, Coop), it will be much higher. Swiss retail economy is organized in cartel and neither Migros nor Coop has any incentive of lowering their price (they make a 30% margin). So if you don't have access to discount stores, It would be closer to 400 CHF/month/person.
-Healthcare insurance : Currently it is 250CHF/Month/person for private mandatory minimum coverage, with a deductible of 2500CHF /year before the insurance starts reinsuring you. Of course you can pay higher premiums and add mutual insurances to have better coverage and lower deductible.
-Utilities : we pay around 35CHF/month for a 60sqm apartment so it is not very expensive.
-Internet : the absolute minimum I could find is 40CHF/month for a DSL connection.
There will be other minor annual expenses, but roughly I think the minimum budget to leave in the area would be 1300CHF/month/person. Which would make 15600CHF per year. Which, from what I can see, would be roughly the double of your budget
On the other hand, Salaries are much higher here and tax lowers than anywhere else in Europe. I am a software developer, and when I was living in Paris my annual salary was 60kEUR brut per year, of which almost 25k would go in diverse taxes. Here I make now 112kCHF per year (not counting bonuses) and only around 15kCHF go to taxes.
Regarding real estate, I looked it up in detail and i concluded it is not worth it here for the moment. To give you an order of idea, for a 60 sqm apartment we pay monthly 1500 CHF. If I want to buy a similar apartment in the surroundings, it would cost us almost 900k CHF! So the brut yield is at 2%, meaning that with all the diverse costs, I am not even sure the landlord make actual money.
Another thing is that when you are a landlord, you pay taxes on the "Eigenmietwert", which is the fictional revenue you would get if you rented your house (you pay the tax even if you don't lease your apartment to a tenant).
So I think real estate is not worth it here. On the other hand, a good thing we have in Switzerland is that capital gains are not taxed => It is a strong incentive to invest in stock market.
