I believe this resort will surprise a lot of people: it will be trend-setting, pioneering a new kind of eco-friendly development, but also one that is much more integrated with the existing local community / landscape. I also see Madrilenos looking to live / rent here, thanks to the excellent links with Madrid. I could go on (and on!), but suffice it to say I think this will actually be a cut above even the likes of Polaris World, and we all know the inflated prices there. In summary, then, your price estimate may be accurate in the shorter term but overly cautious in the medium term, and perhaps wildly low in the longer term ...
