1. Leaking from the roof due to water proofing worn out after x number of years.

2. Low water pressure depending on how the building water pump system is fitted.

3. Noise pollution if the building is beside major road or highway, as noise intensifies the higher the floor

You can only know or experience it if you live there on a daily basis. By that time, it might be too late. Try can find out what kind of water pump they are using (pressure capability) and which floor is the pump located, which is usually some where in the middle floor of the building. Count the number of floors before it reaches your unit and that would be a rough gauge.

I second this suggestion. Less problems that the highest floor 👍✌

Wow! Must have been one hell of an experience for you. Great workout thought ✌

That mitigates the risk of lift break downs or being unserviceable. Should't worry about walking all the way up to the top floor/home

I believe what he is saying is that the unit on the highest floor gets more direct sun light than the units below. Hence the heat built up inside the unit would cause the rubber and plastic to decay at a faster rate

Yes, that is also another factor to be taken into consideration. Units facing the morning sun would be much better than those in the direction of the setting sun.

Than I would say that is pretty adequate as long as the management maintains them on a regular basis to ensure all 6 are functioning most of the time 👍👌
