There is always a low period for every industry and even the property market.
Rental is soft but not crashing. Sometime when a unit is not rent for month and months...agent and owner need to ask themselves, are their expectation align to the current market condition. For example: rental market demand is $3.5k/month but landlord asking $4k/month and there are a few option ranging from $3k to $4k for the comparable unit size. As a tenant, which one will you rent first?
From $$$ point of view, let see $3k *12 month = $36k/year.... if the $4k rental unit can be rent out on the 4month (waterview unit case) $4k*8month= $32k/year. Thus for the same time period, holding up your rental at the high spectrum of the market may not be a good idea.
Remember...property investment in Singapore is long term, it depending on the following:
1) Holding power (if you have pass 100% in cash or have 80% slash up in ur cpf or other investment)
2) Occupancy rate ( Even if you get $0 rental after minus your mortgage/property tax/maintenance charges, it is still not a bad deal as people are paying your mortgage for you)
3) Brave heart to weather through the soft period now.
