House prices in Sedan

At the median sale price, a 90 m² home costs €86,580. With 10% down and a 30-year mortgage, the payment is €337 a month. The HCSF caps it at 35% of a household's income.

Owning a 90 m² apartment costs less each month than renting it. Owning counts interest, running costs and the return the deposit could earn, at apartments' median sale price; rent is the asking rent. Repaying the loan is saving, so it is left out.
