Is this business for sale?

I'm an Expat looking for personal loan and have a credit score above 780. The amount (AED500,000) is for real estate investment back home, Salary is 15k and with 10k monthly saving. I am open to transfer my salary to new bank (provided our company is listed with them) Is there a website to compare interest rates of different banks ? Apart from insurance, arrangement fee and closure fee what factors need to be considered. Are these fees negotiable?
