Soy danese y quiero alquilar una casa (larga temporada - 5-10 años) en España para vivir todo el año.
Pienso es más facíil si es por una agencia, pero si es una persona/propia privada? 

Necesito un abogado local antés firmo el contracto y pago?

(In Denmark we use standard contract and I have never had any problems with any of the owners I have rented houses or flats from.)

I can document I'm pensionista and get my pension from Danish Government every month no matter where in Europe I live. 

All my banking/payments are Internet Banking, and ?should I take prints and show my future house-ower/agencia these documents from my bank, who shows I have paid my rent, electricity, insurance, and all my monthly bills always on time, and always the 1. day of the months?

?Can you give me some advice before I sign a contract? 

I'm 55 years old, not rich, I live alone, and I have no relatives or close friends in Spain. I need to feel secure of in my future Spanish rented house regarding the house owner, when I always pay my rent on time and takes very good care of house and property like I always do.

Muchas gracias, Pia
