House prices in Siero

At the average appraised value, a 90 m² home costs €140,778. With 10% down and a 30-year mortgage, the payment is €537 a month. Spain sets no cap on the payment; lenders must assess each borrower's solvency.

Owning a 90 m² home costs less each month than renting it. Owning counts interest, running costs and the return the deposit could earn, at the appraised value; rent is the mean of new leases. Repaying the loan is saving, so it is left out.
