One of my key concern is always maintenance fee, if not mistaken Twin Arkz increased from 0.38 to 0.51 after 2 years. And it can only go higher and higher later, how to afford leh....

Yes management decide but if that's what is required then you still have to maintain it. My concern is why started at 0.38 and within 2 years increase 30%. Shouldn't Exsim foresee 0.38 is not enough?

Thats how they entice people to buy it... 0.38 is probably a subsidized rate. (of coz already factored into the selling price...)
