I did my reno a year ago and we did take a look at reno loans in end 2008 when we were considering to splurge and take loan or do simple reno.
Some banks and very strict criteria and even if their rates are good, you may not be able to get a loan. So need to be realistic also.
So far from what we researched, RHB gives good rates and chances of approval is higher also. You may also wanna check with your contractor/ID cos some of them have linkups with banks/agents and may give better rates.
