There are few expressions in real estate more powerful or more overused than off-market. Tell a buyer that a property is available online and they will calmly scroll through the photographs. Tell them it is an “exclusive off-market opportunity” and suddenly the same property feels rare, urgent and possibly too good to miss. But let’s clear something up: Off-market does not mean undervalued. It does not mean undiscovered. And it certainly does not mean it is a better property.
