Las deudas con la comunidad de vecinos pueden disminuir notablemente el valor de venta de una propiedad. According to the Horizontal Property Law, owners must be up to date with payments for the proper maintenance of the property. In practice, these debts often lead to negotiations where the buyer asks for a reduction in the price to assume the outstanding debts. To avoid this negative impact on the sale value, it is advisable to be up to date with all payments and to obtain a zero debt certificate before putting the house on the market.
