Should I sell gold to buy a second home, or is it better to pledge it?

ET Wealth Reader's Query: I am 45, and want to buy a holiday home, or what may be called a second home. I do not have any major financial commitments apart from my two daughters’ education. I have also been investing through Systematic Investment plans (SIPs) for the past two years. Should I liquidate my gold investments to buy the second home, or would it be better to pledge the gold instead?
