I hope my views can help you out....
Assuming that you are already fix on the location.
I can give you one real life eg. When a friend of mine was looking for a place to stay in Jurong, he viewed hdb & condo. That time, getting a condo is within his budget but of cost,there is alway question of risk and so on. Therefore, He decided to fully paid his hdb instead. If you ask me now, I can tell you He regretted....He regretted not wanting to take loan and he regretted not taking risk.
4rm = 230k then, today 430k.
Parc Oasis = 450k then today 900k (smilar size to hdb about 1100sqft)
And if u throw in more, westville (99lh landed) = 850k then today 1.4mil
Do your own calculation and if you can afford, go for it. Assuming the market is still good in 5yrs time
