The general answer to that is definitely worth. But (there is always a but) is the location good? is the developer OK? Is the price around that area similar to your condo price?

As for affordability, it solely depends on your lifestyle, assuming you have no other loans, your mortgage will be around RM2500 to RM3000 which is about 50% of your household income, should be no issue.
I do advise to plan your housing loan based on your current salary and lifestyle and not based on future increment

As for the usage, as this is your first house, then usually the purpose may not be as important, every family should have its own house. But if this is your 2nd or third then the purpose becomes important.
