U should study the market value b4 taking the dive.

Then, u can 'do something' b4 the evaluation is out. U know, like 'be friends' with the valuer. (of cos, this is wrong ethically if not legally)

Now that the evaluation is out. No way.

U may try applying from another bank.

BUT beware, the current price hike on property is thanks to the low interest rates. Economy is still heading south.
