1. Check your keys. Make sure each key, even the one for your letter box, opens the corresponding doors properly.
2. Switch on all lights, and ensure that none are blown or sport faulty starters.
3. Turn on all taps, faucets and showers, and let the water run. This way, you can also find out of something's choking up your sink. Do take note that BTOs do not come with showers installed, so bring along a rubber hose to attach on the tap. Flood your floor and check whether it drains out quickly. If it doesn't, then perhaps your floor wasn't slopped properly.
4. Have a sip of the tap water after you've deemed it clean enough. It should taste fresh and free from corrosion. Plus, there should also be no unnatural particles floating around when you fill up a clear glass.
5. Open every window in the house to their maximum capacity. Check that they are functioning properly, even the handles. These should be tightly secured, and easily turned and locked. Forcing the handles into lock position will only loosen them and since these are dead-bolted into the window frames, the only solution around it is to re-bolt them onto another area. Not only will this leave unsightly holes, your handles will also not be level with the rest.
6. Flush your toilets, and observe how long it takes for the water tank to fill up before you flush again.
7. If your unit comes with a fancy accordion pole hanger for drying clothes, play around with it to ensure everything is bolted properly and its mechanisms function smoothly.
8. For tiled walls, take a 50 cents coin or a marble, and tap on each tile to check if it's hollow or loose.
9. Be on a vigilant look out for any water leakage or damage on your ceilings, especially after the neighbours on the floor above you has moved in and begun their renovations.
10. Remember that just because the flat is newly built, its fittings such as pipes, gates and windows are brand new too. Other things that you should take note of are signs of rust, cracks on the toilet bowls and sinks, and window rubber linings that are not dried.
