I  appreciate the services of a good mortgage broker and am very happy to pay  if he has got me an exceptional deal, especially after dealing with some duds. Good service should be rewarded.   My broker got me  a  commercial loan for  4.93%,  where other brokers couldnt get a loan, or the  rate was higher than they said it would be.  I would be wary of the competency of somebody who cuts rates in order to get  enough work,  and how hard they would work to get the best  deal,     The best deal may not be the best rate either. 

I  have found ANZ the worst  bank on a few ocassions they wouldnt give a loan, when others  even tho they had less security, said no worries you are in a strong position being West pac, ST G and bank west..  ANZ tend to sneak up rates and are unco-operative with short term loan limit extensions, make promises you can have X amount then change their mind and not deliver. Of  the loans ive put out for tender ANZ were the lest competetive or they didnt even submit an offer.
