Hi Sonya, I suppose I have the complete opposite opinion of windtalker. I purchased on CDA and found it difficult to get any decent advise online beforehand, so hopefully this clears things up for you:
Are they easy to rent out short term?
Yes in Summer, as I suppose most places in Spain. We have been booked all summer. Winter doesn't see much tourism to the area so the odd booking here and there. (Camposol is 10 minutes down the road, so would likely see the same).
Are there bars/restaurants nearby?
Yep - several bars and eateries on site. Best restaurants are down on the Port (puerto de mazarron) - about 20 minutes drive. There are also great indian restaurants at Camposol.
Are there grocery shops nearby?
SPAR shop on resort - mercadona, lidl etc. all within driving distance.
Are there any plans to change/close down the golf course?
The golf course has recently reopened following closure over covid. Looks like a lot of time and money is going into it, which will hopefully be a great thing for the resort.
Have there been any problems/ safety concerns in the area?
Nothign major. Summertime see's a lot of Spanish tourists who stay for weeks / months on end. Kids get bored and the minority will cause some issues (breaking garden lamps etc.). Defintiely annoying and I think all owners would prefer it to not happen at all, but it doesnt make it a bad resort, and the issues we have have been dealt with by 24/7 security and the police. Outside of July / August doesnt really see any issues that I can note. At the end of the day its how you take it - I see it as I pay community fees to ensure my property is safe and secure and protected by patrolling security and CCTV year round, with well maintained gardens (we are on Jardins side) - the little issues havent affected me directly and I think it would be a rare case if you were.
Anything you wish you'd known before purchasing?
Be aware of the Non residents tax for renting out your property. Its high, but if you work your money right you can still make more than enough to pay your yearly community fees.
In response to windtalker 'CDA is not a place you would pick to go on holiday', I think that is entirely wrong. Yes it depends what you want from a holiday, but CDA is perfectly situated between the mountains of the Sierra Espuna where you can do a lot of adventure activities, and the coast with gorgeous beaches - Yes you will likely need a car if you want to go off resort, but the area has enough going on to keep anyone happy. If you prefer chilled days on the roof terrace reading a book, or chilling in the pool, then you dont need to leave resort at all.
Hope this helps give you a bit more of an insight!
