Hi there,
We moved here three months or so ago so I'm no expert but these are the things I noticed.
I would definitely live near a wet market. You save loads of money on groceries and its funner than a supermarket which can get tedious. I don't actually live near one but I will for our next move.
I also wish I lived really near (like next to) a MRT station.
To save on electric, look for a place with ceiling fans in every room. I hardly use the aircon and my electric bill is much cheaper compared to my friends who live in the same layout without ceiling fans.
Look for a place that has a nice breeze/sun light so you can hang your clothes out to dry instead of putting in dryer. Again, you will save money.
Good luck!
