Purpose of having good credit when you are well-off?
A $250K earner might have $4M in retirement savings and $500K in available funds, but doesn't wish to spend all his liquidity on the house. In general, a house might cost 2-3 times one's annual income. It would take many years to get that saved up. They might want to have the house sooner.  It all goes back to choice, priorities, personal preference.
