I mean the property price itself is already at a minimum of RM782,000. The repayment or rental should be at least 2k-3k?

Yea, but it really depends on situation. With Houzkey, you can exit after 5 years with zero reasoning, and with a low monthly rental, it's still ok if you want to manage your cash flow, especially during this pandemic. You also have the choice to own it after a year with a more lenient review if you're getting a mortgage from MBB.

But if you have a stable job that allows for you to keep up with the monthly installment of a mortgage, and you want to own this property eventually or in the future, I recommend you to skip Houzkey.

All in all, it's a very situational thing if you want to take Houzkey or not.

before commenting on density i think you may need to see yourself the land size that the project is at.

For serene its almost 8 acres, 894 units in 8 acre lands is not that dense. What dense is like M Vertica which is around 11.25 acres but 3,600 units. (https://www.theedgemarkets.com/article/cheras-m-vertica-%E2%80%94-built-sophisticated-urbanite)

Another example is Lot 15 Subang, it has 361 units but a land size of 2.23 acres. (https://www.propertyguru.com.my/new-property-launch/lot-15-sjcc-4044341)

Even nearby Acruz is having 681 units on a 2.02 Acres of land. (https://propertyland.my/the-arcuz-kelana-jaya)

So when we talk about density we also need to learn about the total land size that the project will be at.
