Approaching this from another angle, a person that rents properties for customers I would like to provide another view on this
We regularly get enquires from people that want to rent long term as seen by the renters, 2-3 months June-September and expect to get the much lower rate. We make it clear that the MINIMUM contract term to qualfy is a 6 month contract which normally means that they don't book, or a 3 month rental at much higher rates to include the utiliity rates
Being honest if someboday has a decent property in The Playa Flamenca area they should easily be able to get enough holiday rentals to more than cover the grief that could come from a 3 month period
I would also adviise that commiting an initial 3 month stay in the Summer months, when the weather is hit and the schools are closed really isn't commiting to really trying a frresh start in a new country, try a wet cold November day to really get a feel when employment is scarce and the bills start coming in
If you are querying the Summer rental rates now you really shouldn't consider a life in Spain
