Many buyers of small or shoebox units do so due to affordability and the prospect of renting out the unit as an investment and passive income source (Paya Lebar condo aims to score home run; March 10).

However, several issues related to short-term leases and illegal subletting are, as yet, unresolved.

Until these are settled, the authorities should consider limiting the number of shoebox units offered at future developments to, perhaps, 15 per cent of the project.

While Singaporeans embrace new business models, opportunities and technological advancements, we must also be socially responsible in keeping peace with all our neighbours in a high-density city living environment.

It is also a matter of vigilance, public safety and security.

Many condominium units are not permanently occupied. These absentee landlords cannot be relied on to enforce strict adherence to terms of tenancy, compliance with local laws, peaceful occupation and good neighbourliness.

It is also unfair for all subsidiary proprietors of condominiums to help shoulder the cost of repairs and maintenance of the estate due to the wear and tear caused by the influx and traffic of short-term tenants, and the use of the condo's facilities by them.

Short-term leases or tenancies will corrode neighbourliness if they are not regulated.
