Difficult really to give a definate answer on rental yields for Corvera due to the changes taking place at present with the club house and airport soon to come on stream.
The yield is also going to be dependant on the purchase price obtained in the first place, and wether you pay cash or take out a mortgage( if you are looking for a bargain resale property I have a 2 bedroom 2 bathroom penthouse for sale at €130,000) We currently rent out several 2 and 3 bedroom appartments on Corvera on long term rental contracts at €400/€450 per month, with holiday rentals varying dependant on the season and property from €180 to €300 per week.
I know these rates aren't as much as we'd all like to be getting but there is a lot of property available in the region at present and this is keeping prices subdued.
You will probably find that long term rental is the better option on Corvera as although short term/holiday rates seem attractive at first the income is more sporadic and by the time you have taken cleaning fees,gas, electricity and water bills into account the yeild achieved can be far less than the long term rental yields.
Having worked in banking and estate agency/property management for 25 years I am also able to inform you that it is possible using a little known allowance to get tax relief on the income generated if you are a UK tax payer and not have to pay any tax at all on this for a number of years into the future. Indeed acting before next April means you can actually offset against income from other sources not related to the property. (this obviously increases the yeild to you).
We are looking to add to our portfolio on Corvera at present and would be more than happy to discuss our services if you feel we can be of assistance.
Hope this helps you to make your decision and please feel free to personal message or phone me for further details.
Best regards
Tom
