Please dont take this as gospel truth, it is just my understanding and you need to get it confirmed by an expert but roughly speaking it will be:

Taxes: 

o your mortgage interest charges are an expense that you can offset against your income, reducing your taxable income;

o you pay an additional imputed income tax based upon the rent that you might have paid if you were renting it.  In other words, your income is artifically increased by the amount of rent you arent paying by owning.  Ask whoever you are buying the house from, they can tell you what the imputed vale will be as its stable frm one year to the next

Insurance:

o batiments

o contents

Charges:  whatever comes with the place you buy.  Perhaps building or grounds maintenance, perhaps the divided cost of a property maintenance company, perhaps communial heating, varies depending on the property.  Some of these charges may also be able to be placed on your tax return to offset against your income. 

Oh one other thing, if you are on some kind of tax at source arrangement for the first few years of living in the country where your taxes are automatically withdrawn from your salary and you arent accustomed to completing a tax return each year, then the moment that you buy a property that will stop and you will then need to complete a tax return each year. 

Hi there, 

Like hucklewoo, this is just based on my own understanding.

You also have a property tax that is around 1,600 CHF pa that is waived for 20 years if you have an THPE or Minergie building (green energy efficiency)

You will need to pay back the second tranche of the mortgage so that you reduce the debt to a max of 65% before retirement.

You have to pay the notary fees, which are 4-5 % for an old build (you can use the calculator at https://notaires-geneve.ch/fr/frais-immobiliers). In addition, you need to pay notary fees to get your mortgage registered with the notaire, again check out the calculator for the cedule hypothecaire. You might be able to take over the seller's. 

Are you buying a house, or an appartment? If the latter, it will most likely be a PPE (property par étage). It may also be a PPE if it is a terrace house, so check. If that is the case, then there will be a syndic charge/regie, plus a contribution to the renovation fund. When you are looking at a PPE, do a health check on the renovation fund. You do not want to find out that there will be very pricey renovations due in the next couple of years after your purchase, and not a lot in reserve to pay for it. 

Check whether the road your property is on is public or private - there might be charges. Even if public, you will be responsible for clearing the snow outside your home (I think).
