Should always go for completed or nearly completed properties if possible. With this global economic crisis, I don't really trust those developers, big or small.

I think 5k not enough. (Know that you can withdraw money from your EPF account 2 for this?)
There will be all kinds of legal and stamping fees to pay.
Sometimes they free you legal fees, but you'll have to pay stamping fees.
So ask carefully.

Then somewhere down the road, legal fees for the strata title.
Every month, maintenance fee and sinking fund.
Every 1-2 years, maintenance office will try to get an increase.
Yearly/Bi-yearly quit rent for the DBKL/MPSJ or whatever.
Indah Water payment.

But anyway, don't give up easily.
Everyone has got to start somewhere.
Unless you have other 'abnormal' expenses.
If the bank approve your loan, then believe that you can do it.
