Is a Tenerife rental contract there to be broken?

A Tenerife rental contract or an agreement in any other country is neither here nor there.

That means that a contract should be honored and not broken all over the world.
Some people even respect and honor verbal agreements.

Imagine, you go to a lawyer to ask for advice to make the best rental document for all parties concerned.

Your renter then signs that he will rent for a whole year. Of course, the rental price should be higher, if it was
 for less than 12 month. That's why holiday home rental costs so much more.

So just figure that the Spanish legal help who calls himself an 'abogado' by trade even may sum up the total amount for 12 months in writing.  Why? To avoid misunderstanding...

Unfortunately, the renter tried to be clever and never even paid the 11th month. His reasoning was that the landlord could keep the deposit which amounted to 4 weeks, instead. He reasoned that nothing was broken or damaged by him. It's highly illegal to take advantage of such a repayable deposit called Fianza and use it for rent.

Should he have been taken to court for that? Not worth the hassle... Right?

What difference does the situation make to the rent payments all in all?

The renter scored  a better rental tariff.  He had a cheaper monthly rent than agreed by cheating on rental terms.  Why?  You sum up all months paid by him which you then divide by 12 as by contract. The result is a cheaper rent. So he broke his word and the written Tenerife rental contract.  He is not a man in my eyes but, a cheap fraud.

I have an idea how to avoid such a situation for the future.  However, I would be most interested to hear,  how you the reader would solve this rental problem.
