I can start out by saying that the general build quality and legality of the villas on HDA is very good, considering the original pricing they seem to represent good value but it really is about why you are looking to buy, investment or own use
With the airport, which we understand has again been delayed, will have an impact on the local resorts, both good and bad. There will be some background noise but really until the first planes fly it is difficult to see the real impact. The planes cannot fly over Corvera because of the mountain range and they have to turn on departure and approach to avoid Alcantarilla, , on whet appears to show on the recently submitted flight plans, over HDA, but again until there are jet flights it is impossible to tell
The resort, like most of the other local resorts has money problems, for the properties around the village that recently didn't sell well and I believe that the bank have now taken them back, again you need to perhaps make contact with the resort Administrators before you buy anything
I go onsite fairly regularly and have not really noticed any major impact on the community areas, security is still there, the streets were clean and gardens maintained at present
Finally the flies, I live on Corvera and in this area yes we do suffer and the spraying tends to be more for the mozis but the solution here that works well are the pot type fly traps
