i've been to the PV before, and I dont think it would be a good investment. Right now those renting are students (mind you there are a lot more foreigner these day there)
What happens if the college near that area relocates or more foreigners staying there compered to locals? Also the wear and tear at the PV is fast deteriorating, no thanks to the high student population. Carparks is a problem.

For 500k, you can get a really nice condo somewhere else, no need to even buy subsale one buy from developer staright.
