better buy a landed wit individual title...

individual title always has the value than the strata title... just like freehold always has the value than leasehold

If my understanding is correct, the advantage for strate title over individual title is if anyone (somehow there are such ppl) refuse/ignore in making monthly payment, he can be barred from entering the area.

strata title for landed is actually same as condo, with proper G&G.
all properties within the boundary (except those things within your unit's land area) are share and belong to the residents, even the extra vacant land, swimming pool, playground, garden, drainage, lamp post, road, and plants are all have to maintained by the residents.
just that strata landed in malaysia still very rare, majority of us still cant accept the restrictions in DMC, like no extension (even if you bought with a bigger "footprint" unit), no outdoor painting, no pets, no illegal parking, no car wash in front your house, no clothes hanging and blablabla... and also, the maintenance fee & sunking fund, base on built up too, a unit with 3000sf built up have to pay more than a thousand/mth is not a surprise.
all residents are bound by the DMC law, whoever did not make the payment will not able to sell their unit until the overdue amount + agreed interest settled. being barred from entering the area or not? i hav no idea.
from what i know in DPC, foreigners appreciate strata title than individual title as more neat and more uniform, and also more friendly kind of environment (no fencing maybe?).
just my 2 cents, any mislead please correct me, we are learning..

strata titles (also for landed) is governed by the terms and conditions in the DMC.

now why the hassle? it is so that every one in the community plays their part in the maintenance of the neighborhood. usually this is necessary in creating/maintenance of a lifestyle. you can't do that with individual titles as no laws bounds one owner in participating in maintaining the common areas (unless they enter into another agreement altogether). Strata titles also mean the areas can be marked as private for residence (like gardens, roads etc). In an individual titled area, all other common areas are accessible by the public by law

it is not true for a strata title property no extension is possible. usually the DMC will govern this and you will need to obtain permission from the property managing body.

as for the effect it has on the property, really, strata/individual title is pretty much the same.
