Unfortunately, the real estate market in Southern Spain is currently a buyers market. This can be very frustrating if you are a buyer desperate to sell. You will always get people that are willing to make an offer to buy your property.
However, I think that all the phases in Don Juan are a good buy based on the developers original selling prices, the location is great and the infrastructure and facilities will only get better over the coming years. I think Carvajal will become a very desirable location to live and holiday along this stretch of coastline.
Don't get offended by people offering stupid prices, they are just trying to make quick money or trying to get a good long-term investment. The fact that they are interested means that the development is worth investing in.
Danazcurt, I'm in phase 1, block 2, on the planta baja level (sticking out terrace) it will cost you 300,000 euro minimum to buy my apartment. Could also offer you my storeroom but would want at least 10,000 euros as is a big one at 3.14m2. :-)
