5 grand USD right?
Rent cost there as much and even more than in US. $1k for 2 bedroom. But ghetto is ghetto, no matter if it's ghetto in USA, Singapore, or Russia. I can tell you a thing or two about ghetto living. In center and closer to center prices are always higher. Prices also higher in summer, so called season. You want to look for rent away from the city center, pick a bus and go to its end stop, that sort of away. There you could rent a room in a nicely build mansion and pay less.
Chances of you coming from India to Singapore and renting a place for a good price right off the bat are very slim. You'd need a friend there. Have you tried social networking sites?
Find out how they rent there, and where. You want bare minimum, a nice sized room at the end of the city. Because 5k is not real money in places like Singapore and Moscow.
If you go mainstream real estate agents, expect to pay $1500 for a place, and then $800 for food.
One more thing, don't ride a scooter or bike, either ride bus, or buy a car.
