landed property is no different from condo or penthouses, except that for condo, the estate will take care of whatever that is outside the house which including roof leaking, painting, water seepage, while for landed owner will have to take care of everything from A-Z.
For landed property, there are many hidden expenses. One which people rarely talk about is their bill for pest control, be it snakes, rodent, and termite. And such expenses are recurrence because subterranean termites can happen anywhere and anytime. I think for a routine check plus baits, it should come up to about 2 to 3K per year.
Another major expenses which you cant avoid is air condition, because every 10 to 15 years (at max) you will need to install new aircon system which include re doing all the gas pipping. For landed, the bill will easily come up to >$40k upwards. (in this area, there is to replacement for displacement)
Other bills to consider will of course be automatic main gate, alarm system, electrical system etc. And if you have a pool, the cost of maintaining it alone will cost more than the maintenance fee of most condo. The worst part of it is that, most landed owners wont even bother to use their own pools because they are too small.
And like in condo, those decking around the pools will usually need to be refitted again after every 10 years, and that will easily cost $50k depending on size.
In this business there is no replacement for displacement. The bigger the house the more repair you need. And for landed you will never be able to get the same economy of scale when sourcing for contractor as you dont have a professional estate manager to take care of the place.
$2-3k PER YEAR alone for pest control? IN SINGAPORE?
YOU MUST BE JOKING?
