it is not as high as 15%.
we take Terraza Eco World as example, monthly fee RM 550, yearly RM 6.6K, 10 year is RM 66K. The initial price around 1M, so it is around 6.6% of your acquisition cost. If for own stay, IJM landed also paying around RM 100 for security fee, so Terraza is actually need to pay extra RM 450 per month, 10 year 54K, around 5.4% of the acquisition cost. My friend owning a Terraza, so i have clear idea the costing.
for TA Arahsia, not really sure its monthly security fee, assuming it is RM 400, 10 year around RM 48K, Launching price i am not sure, maybe RM 700K after discount, around 6.8% for 10 yr to the acquisition cost. If take the difference to Rimbayu, only 5.1%.
If compared to low density Rimbayu like Scarlet, the security fee is RM 180 per month for an individual title house.
Anyway, in short term, the high monthly security fee for Strate Title, it will suppress the subsales price, as most of the people not willing to pay more for nothing, in long term, if the strate title housing area can maintain everything nicely compared to individual title, then its value will show in the subsales price, but again, the appreciation is come from the owner monthly contribution, so the additional gain might not really a lot compared to individual title. So the strata title only benefit to owner to enjoy the good landscaping and etc, but not really benefit to return of investment.
Of course the cost is compound with 5% interest, 2% inflation and 5% YoY increment.
If your RA is full of kiasu want to look like botanic garden and stubborn defaulter then for sure it will be 200% by end of 5th year. Therefore, nice place you paid and burn (aka enjoyed), not nice place then no one wanna take over a fire pit. Never seen any example earn back maintenance fee.
