If I have a budget of 3000 for rent every month, should I get a 3000 furnished or 2500 unfurnished and get 500 a month in rental furniture? It seems the term "furnished condos" are very different from ad to ad.
The other problem in buying "furnished" is you end up with all the old crap the landlord doesn't want. Buy some stuff at Ikea... or do a search for furniture rental in Singapore... at least you'll get the furniture you want and not the tossed off dregs that the LL wants to charge you $500 a month for.
Note that in many ads, "furnished" doesn't mean beds and couches, it means white goods like a stove, refrigerator, washer, and dryer. Unless these have been lying around since the Japanese invasion, paying for these items as part of the rent is a good idea, but be sure to be clear in the lease about who pays for failed equipment and/or repairs.
