Hi I am sorry but haven’t been in the site fir a while due to personal reasons.
I am sure by now you have sorted yourself out but just in case....
La Manga Club has a few estate agents on site snd can help you.
Also it is open all year round and has a thriving community. I am assuming some of the answers you were given was for La Manga - the strip which can be a bit quiet in the winter as quite a few properties there are owned by Spaniards as their holiday homes.
Pm me if you need any more details.
