I know this was posted a few months ago. Just a bit of advice that your friend can take or leave. Las Palomas has drastically decreased in quality and there is plenty of talk that it will soon crumble. The property is beautiful, but it is poorly mismanaged (vast understatement, I realize) and many owners have lost their shirts as a result. The new management is significantly smaller in number, but I find them to be equally corrupt.
If it does miraculously survive, and although your friend is not an investor, her future potential purchasers might be. She will limit the pool of potential buyers by sticking with a place that restricts owners from renting on their own (unless they pay all kinds of fees, and give Operadora a cut of the rent).
Good luck, either way.
