Is it that much difference for the rates of utility n quit rent for serviced residence and condominiums?

Is it worth it to buy serviced residence for own stay?

To be fair, even those units put up for rental will also attract low quality tenants if the owner doesn't mind renting it out at below market price. A friend of my sister residing in Scenaria recounted bumping into Thai/Viet girls, China dolls and uncivilised Kepong kakis staying there. And this is a condo which banned airbnb.

And in Shamelin Star, when I was there a few months after it VP'ed, I noticed a number of people who swam fully clothed in its Olympic-sized swimming pool and I saw low-class folks among the decent ones on the facilities floor itself, which gives the impression that a lot of the owners throw the rental price there.
