It depends on the purpose of the purchaser .... buying for investment and buying for own stay might have very different criteria
I think depends on the purpose as well. If for own stay, I will definitely prefer gated and guarded landed property. Although new type of high rise property can have more space, but for me, I still prefer landed property as I can utilise the extra space to make my own design or plant some flowers or stuff.
Some people prefer condo unit for its facilities... however the current trend by some well known developer...they build club houses with facilities for its landed property owners... ofcourse owners need to pay extra to enjoy the facilities.
Landed property with club house facilities will be my choice. If the landed property is situated on a hill and comes with a view, it is a bonus
Landed. Being raised in a small town where landed houses are affordable, it's not easy to accept high rise condominium.
Condos have the advantage of a better views, equip with facilities and a slightly better securities. But it don't offer you with a space for your own gardening nor a kitchen outside of the house.
For investment purpose, as seen so far, condos seems like a better option with a better rental yield.
The only dilemma would be that, nowadays, we don't live in such a big family. A landed property where you stay alone could be a depressing one. It's important to see what are the headcounts of the occupants to decide.
