No agents in particular as they do not have a centralized system and tend to hold their own batch of
property from landlords. If they are representing the landlord, they do not take commission from you but if they need to reach out to other agents then that agent will collect from the landlord and they will collect from you.
Becareful when searching for places and dont let them hype you too much. If you want something simple, you can try the
condos located in Geylang area (red light district is in the lorong 1x - 2x) but that is a good place to start and should be ok for a single person/couple. There are quite a few foreigners living there since they are newly built 'shoebox'
condos for between $1800 - $2200.
Hope it helps
