Naah, you said yourself that property moves in cycles - they can just wait for prices to rise again after they've plummeted. They'll get their money back and probably make a little profit. They won't get rich quick, but neither will they end up begging in the streets.
Forgive me for saying so, but quite a shallow argument.
If you load yourself up with debt to pay for an overpriced house, your quality of life suffers and you pay back more money in interest and principle. Money which could have been better used for travel, health, education and fun. Surely it's better to educate yourself a little and buy at the bottom of the cycle when prices are cheap ?
Cyprus has so much more going for it, it's prettier, less touristy (Los Americos is lager lout heaven), nicer beaches, nicer people, more space (it is 4 times smaller than Cyprus with the same population) and overall a nicer place to live.
While I love Cyprus this is a highly optimistic portrait of our little island ! Sure it has great points, but do not forget the rip-off merchants, very high cost of living, poor wages, mad driving, stifling beaurocracy, overdevelopment, rubbish strewn countryside, etc etc.
Also I think you are too generous with your portrayal of our beaches. The best beaches are in turkish occupied territory. Limassol and Larnaca have poor beaches, Paphos has one good beach and a few fair ones and Ayia Napa has several good beaches (but very overcrowded)
