Which home renovation loan should I take on?

Usually, foreign banks give a higher loan limit than local banks (only in general, not for all cases) so people may face stricter or lower loan from local banks such as DBS.

Also, banks give out promotions periodically, so it could be that CIMB and Maybank had much lower rates a few weeks/months ago and now the promotion rate has ended and DBS just launched theirs. =)

Go for the best rate of the period you are loaning, it's the better info compared to reviews of the past.
