I don't like to encourage a credit card, but if used wisely, should I encourage my son to apply for one with the sole purpose of helping to build a credit record for his first time mortgage? Or is this the wrong thing to do? He is 19, living with us at home, working full time, saving hard into a lifetime isa with the hope to buy a small flat in the next 1-2 years or so. He currently has nothing that would reflect on a credit record (ie he has paid his car insurance in full, no phone contract as this is still in my name from when his contract began). Is this the right thing or wrong thing to do to help get a mortgage eventually?
