So I have 1 condo that is just entering almost 3 years now.

now its currently tenanted, but in the future I wish to dispose this property. Is 3-5 year holding time ideal? I will just continue tenancy for the third year, and plan to dispose it next year. (due to personal reasons, I don't wish to own stay in this condo anymore)

Or any sifus have any other advice? recently MRT3 was announced just near my condo, should I dispose before or after the construction finished?

Appreciate your thoughts on this.
